Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202211217062.9, entitled "ULTRA-WIDEBAND-BASED SENSING METHOD AND APPARATUS," filed with the State Intellectual Property Office of the People's Republic of China on September 30, 2022, the entire contents of which are incorporated herein by reference.

[0002] TECHNICAL FIELD Embodiments of the present application relate to the field of wireless communications, and in particular to ultra-wideband based sensing methods and devices. [Background technology]

[0003] Ultra-wideband (UWB) technology is a wireless carrier communication technology that uses nanosecond-level narrow pulses to transmit data. The narrow pulses occupy a wide spectral range and have extremely low radiation spectral density. UWB systems have advantages such as high multipath resolution, low power consumption, and high confidentiality. As UWB technology is applied to the civilian field, ultra-wideband wireless communication has become one of the common physical layer technologies for short-range and high-speed wireless networks.

[0004] To avoid carrier frequency offset and interference between multiple devices, UWB systems typically use single-base station mode or multi-base station mode for sensing. In a single-base station sensing scenario, the operating modes of the transmitter and receiver can be classified as full-duplex mode and half-duplex mode. In full-duplex mode, the transmitter and receiver operate simultaneously. In this case, the transmitter causes severe interference to the receiver. For example, the echo of a weak target is eclipsed by the transmitted signal. In half-duplex mode, the interference caused by the transmitter to the receiver is significantly reduced, and only during close-range target detection can the target echo return before the transmitter switches to the receiver. In a multi-base station sensing scenario, the target reflection path can be eclipsed by the direct path.

[0005] In a sensing scenario, a high pulse repetition frequency (PRF) results in high transmit power, but significantly reduces the unambiguous range R, as shown in the first row of Figure 1. The unambiguous range R, which can also be referred to as the maximum unambiguous range, is R = 0.5c / PRF, where c is the speed of light. A low PRF results in reduced transmit power and increased unambiguous range, as shown in the second row of Figure 1.

[0006] As shown in the third row of Figure 1, a transmission scheme using multiple pulse bursts results in increased transmit power and maximum unambiguous range. Each pulse burst contains multiple pulses. A high PRF of the pulses can ensure the transmit power. Furthermore, periodic transmission of the pulse bursts can increase the unambiguous range.

[0007] The number of pulses included in each pulse burst is the same as the number of sequences included in the transmit waveform sequence set. Currently, the transmit waveform sequence set includes Ipatov sequences and cyclically shifted sequences of Ipatov sequences. Ipatov sequences have perfect cyclic autocorrelation properties, and sequence sets with a cyclic zero correlation zone (ZCZ) can be generated by cyclic shifting. Using a sequence from a sequence set with a ZCZ as the transmit waveform sequence can reduce interference between different sequences within the sequence set. However, to achieve the cyclic correlation properties, a cyclic prefix and cyclic suffix must be added to the transmitted waveform sequence. This increases the actual length of the transmitted waveform sequence, increasing the time required for sensing measurements and causing interference to other devices or applications (such as ranging and communications). Summary of the Invention [Means for solving the problem]

[0008] The present application provides an ultra-wideband based sensing method and apparatus to solve the problem of increased time required for sensing measurements due to the long length of the transmitted waveform sequence. According to a first aspect, the present application provides an ultra-wideband based sensing method, the method comprising: The transmitting end determines a transmit waveform sequence set, the transmit waveform sequence set including N sequences, where N is a positive integer, and the transmit waveform sequence set includes sequences having aperiodic zero correlation zones ZCZ, and the sequences have a sequence length of Q, where Q is a positive integer; the transmitting end transmits Q pulse bursts to the receiving end based on the N sequences, where each pulse burst includes N pulses, and the j-th pulse in the i-th pulse burst of the Q pulse bursts corresponds to the i-th element in the j-th sequence of the N sequences, where i and j are positive integers, and 1≦i≦Q and 1≦j≦N.

[0009] Since the aforementioned transmit waveform sequence set is used, no cyclic prefix or cyclic suffix is ​​used, the sensing performance of the transmit waveform sequence can be guaranteed, and the air interface time can be reduced.

[0010] In a possible design, the transmit waveform sequence set includes P sequences, where P≧N and P is a positive integer.

[0011] The transmit waveform sequence set may include multiple sequences, and the transmit waveform sequence set currently being used by the transmitting end may include some or all of the multiple sequences.

[0012] In a possible design, the transmit waveform sequence set is constructed based on a first matrix, a second matrix, and a third matrix, where the first matrix, the second matrix, and the third matrix are all Hadamard matrices.

[0013] In a possible design, the order of the first matrix is ​​the same as the order of the second matrix. The transmit waveform sequence set may be constructed by the following steps: constructing a sequence set having a sequence length of M(Z+C) based on the first matrix and a third matrix, where M, Z, and C are positive integers, M is the order of the first matrix and the second matrix, Z is the order of the third matrix, and C is a preset value; and constructing a sequence set having a sequence length of M(Z+C) based on the second matrix and the sequence set having a sequence length of M(Z+C) by n iterations. n+1 (Z+C) and constructing a sequence set with sequence length M n+1 The sequence set having (Z+C) includes M×Z sequences, and when a transmitting end transmits Q pulse bursts to a receiving end based on N sequences, N≦M×Z, P=M×Z, and Q=M n+1 (Z+C).

[0014] In a possible design, when a sequence set having a sequence length M(Z+C) is constructed based on the first matrix and the third matrix, each element in the column of sequence number s of the third matrix is ​​multiplied by the element in the column of sequence number t of the first matrix, and C columns of elements that are all 0 are added together to obtain a first processing matrix having sequence number M×s+t, where the first processing matrix having sequence number M×s+t has M(Z+C) columns, where 0≦s≦Z-1 and 0≦t≦M-1; to obtain a first sequence having sequence number M×s+t in the sequence set having a sequence length of M(Z+C), the first processing matrix having sequence number M×s+t is output row by row.

[0015] In a possible design, the sequence length M n+1 When a sequence set having a sequence length M(Z+C) is constructed through n iterations based on the second matrix and a sequence set having a sequence length M(Z+C), 2 A sequence set with (Z+C) is constructed through one iteration based on the second matrix and a sequence set with sequence length M(Z+C).

[0016] In a possible design, M is used to obtain the second matrix to be processed having sequence number M×s+t. 2 When a sequence set having a sequence length of (Z+C) is constructed based on the second matrix and the sequence set having a sequence length of M(Z+C) by one iteration, the element having sequence number w in the column having sequence number t in the second matrix is ​​multiplied by the first sequence having sequence number M×s+w, where w is from 0 to M−1, and w is a positive integer; M 2 To obtain a second sequence having sequence number M×s+t in a sequence set having a sequence length of (Z+C), a second matrix to be processed having sequence number M×s+t is output row by row.

[0017] In a possible design, the transmit waveform sequence set is constructed based on a sequence family, the sequence family including multiple sequence sets, all of which include the same number of sequences and have the same sequence length. For all sequences in any sequence set in the sequence family, the sum of the values ​​of the aperiodic autocorrelation function corresponding to all sequences at a lag τ equal to 0 is the product of the number of sequences and the sequence length, and the sum of the values ​​of the aperiodic autocorrelation function corresponding to all sequences at a lag τ not equal to 0 is 0. For all sequence groups determined based on any two sequence sets in the sequence family, each sequence group includes two sequences having the same sequence number, the sum of the values ​​of the aperiodic cross-correlation function corresponding to all sequence groups at a lag τ equal to 0 is 0, and the sum of the values ​​of the aperiodic cross-correlation function corresponding to all sequence groups at a lag τ not equal to 0 is 0.

[0018] In a possible design, the transmit waveform sequence set is constructed by performing the following steps: add K zero elements between two sequences in each sequence set in the sequence family to obtain sequences in the transmit waveform sequence set, where K is a positive integer.

[0019] The above method for constructing a transmit waveform sequence set is simple, and the transmitted waveform sequences have better sensing performance than Ipatov sequences. In a possible design, the transmit waveform sequence set may be: s1=(1,1,1,1,1,1,1,1,0,0,0,0,-1,-1,1,1,-1,-1,1,1,0,0,0,0,-1,1,-1,1,-1,1,-1,1,0,0,0,0,-1,1,1,-1,-1,1,1,-1,0,0,0,0); s2=(-1,-1,1,1,-1,-1,1,1,0,0,0,0,1,1,1,1,1,1,1,1,0,0,0,0,1,-1,-1,1,1,-1,-1,1,0,0,0,0,1,-1,1,-1,1,-1,1,-1,0,0,0,0); s3=(-1,1,-1,1,-1,1,-1,1,0,0,0,0,1,-1,-1,1,1,-1,-1,1,0,0,0,0,1,1,1,1,1,1,1,1,0,0,0,0,1,1,-1,-1,1,1,-1,-1,0,0,0,0); s4=(-1,1,1,-1,-1,1,1,-1,0,0,0,0,1,-1,1,-1,1,-1,1,-1,0,0,0,0,1,1,-1,-1,1,1,-1,-1,0,0,0,0,1,1,1,1,1,1,1,1,0,0,0,0); s5=(1,1,1,1,-1,-1,-1,-1,0,0,0,0,-1,-1,1,1,1,1,-1,-1,0,0,0,0,-1,1,-1,1,1,-1,1,-1,0,0,0,0,-1,1,1,-1,1,-1,-1,1,0,0,0,0); s6=(-1,-1,1,1,1,1,-1,-1,0,0,0,0,1,1,1,1,-1,-1,-1,-1,0,0,0,0,1,-1,-1,1,-1,1,1,-1,0,0,0,0,1,-1,1,-1,-1,1,-1,1,0,0,0,0); s7=(-1,1,-1,1,1,-1,1,-1,1,-1,0,0,0,0,1,-1,-1,1,-1,1,1,-1,0,0,0,0,1,1,1,1,-1,-1,-1,-1,0,0,0,0,1,1,-1,-1,-1,-1,1,0,0,0,0,1,1,-1,-1,-1,1,0,0,0,0); and Includes s8=(-1,1,1,-1,1,-1,-1,1,0,0,0,0,1,-1,1,-1,-1,1,-1,1,0,0,0,0,1,-1,-1,-1,1,-1,1,0,0,0,0,1,1,-1,-1,-1,1,0,0,0,0,1,1,1,1,-1,-1,-1,0,0,0,0).

[0020] For example, if a transmitting end transmits Q pulse bursts based on N sequences to a receiving end, N≦8, P=8, and Q=48. In a possible design, the transmit waveform sequence set may be: s1=(1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0,0,0,0,0,0,0,0,1,-1,1,-1,1,-1,1,-1,1,-1,1,-1,1,-1,1,-1,0,0,0,0,0,0,0,0,1,1 ,-1,-1,1,1,-1,-1,1,1,-1,-1,1,1,-1,-1,0,0,0,0,0,0,0,0,1,-1,-1,1,1,-1,-1,1,1,-1,-1,1,1,-1,-1,1,0,0,0,0,0,0,0,0,1, 1,1,1,-1,-1,-1,-1,1,1,1,1,-1,-1,-1,-1,0,0,0,0,0,0,0,0,0,1,-1,1,-1,-1,1,-1,1,-1,1,-1,1,-1,1,-1,1,-1,1,0,0,0,0,0,0,0,0,1,-1,-1,-1,-1,1,1,1,1,-1,-1,1,1,0,0,0,0,0,0,0,0,0,1,-1,-1,1,1,1,-1,1,1,-1,1,0,0,0,0,0,0,0,0,0,1,-1,1,-1,1,1,-1,1,1,-1,1,-1,1,1,-1,1,-1,1,0,0,0,0,0,0,0,0,0);

[0021] For example, if a transmitting end transmits Q pulse bursts based on N sequences to a receiving end, N≦16, P=16, and Q=192.

[0022] For example, if a transmitting end transmits Q pulse bursts based on N sequences to a receiving end, N≦4, P=4, and Q=56.

[0023] In a possible design, the transmit waveform sequence set may be:

number

[0024] For example, if a transmitting end transmits Q pulse bursts based on N sequences to a receiving end, N≦4, P=4, and Q=70.

[0025] In a possible design, the transmit waveform sequence set may be:

number

[0026] For example, if a transmitting end transmits Q pulse bursts based on N sequences to a receiving end, N≦4, P=4, and Q=112.

[0027] In a possible design, the transmit waveform sequence set may be:

number

[0028] For example, if a transmitting end transmits Q pulse bursts based on N sequences to a receiving end, N≦4, P=4, and Q=140.

[0029] According to a second aspect, the present application provides an ultra-wideband based sensing method, the method comprising: The receiving end receives Q pulse bursts from the transmitting end, each pulse burst including N pulses, and the jth pulse in the ith pulse burst among the Q pulse bursts corresponds to the ith element in the jth sequence in the transmit waveform sequence set, where i and j are positive integers. The transmit waveform sequence set includes N sequences, where N is a positive integer, and the transmit waveform sequence set includes sequences having aperiodic ZCZ, the sequences having a sequence length of Q, where Q is a positive integer, 1≦i≦Q and 1≦j≦N; the receiving end correlates the Q pulse bursts with a local sequence set to determine information about targets within a detection range, where the local sequence set is the same as the transmit waveform sequence set, and the detection range is related to the size of the ZCZ and the repetition period of the pulse bursts.

[0030] Since the aforementioned transmit waveform sequence set is used, a cyclic prefix is ​​not used instead of a cyclic suffix, the sensing performance of the transmit waveform sequence can be guaranteed, and the air interface time can be reduced.

[0031] In a possible design, the detection range is half the product of the size of the ZCZ, the repetition rate of the pulse burst, and the speed of light.

[0032] In a possible design, the information about the target includes target range information or target velocity information.

[0033] In a possible design, the transmit waveform sequence set includes P sequences, where P≧N and P is a positive integer.

[0034] In a possible design, the transmit waveform sequence set is constructed based on a first matrix, a second matrix, and a third matrix, where the first matrix, the second matrix, and the third matrix are all Hadamard matrices.

[0035] In a possible design, the order of the first matrix is ​​the same as the order of the second matrix.

[0036] The transmit waveform sequence set includes the following steps: constructing a sequence set having a sequence length of M(Z+C) based on the first matrix and the third matrix, where M, Z, and C are positive integers, M is the order of the first matrix and the second matrix, Z is the order of the third matrix, and C is a preset value; Based on the second matrix and the sequence set having a sequence length M(Z+C) by n iterations, a sequence set of sequence length M is obtained as a transmit waveform sequence set. n+1 (Z+C) and constructing a sequence set with sequence length M n+1The sequence set with (Z+C) contains M×Z sequences, N≦M×Z and P=M×Z, and Q=M n+1 (Z+C).

[0037] In a possible design, the transmit waveform sequence set is constructed based on a sequence family, where the sequence family includes multiple sequence sets, all of the sequence sets including the same number of sequences, and all of the sequences having the same sequence length.

[0038] For all sequences in any sequence set in a sequence family, the sum of the values ​​of the aperiodic autocorrelation function corresponding to all sequences with a lag τ equal to 0 is the product of the number of sequences and the sequence length, and the sum of the values ​​of the aperiodic autocorrelation function corresponding to all sequences with a lag τ not equal to 0 is 0.

[0039] For all sequence groups determined based on any two sequence sets in the sequence family, each sequence group includes two sequences having the same sequence number, and the sum of the values ​​of the aperiodic cross-correlation function corresponding to all sequence groups respectively with a lag τ equal to 0 is 0, and the sum of the values ​​of the aperiodic cross-correlation function corresponding to all sequence groups respectively with a lag τ not equal to 0 is 0.

[0040] In a possible design, the transmit waveform sequence set may include the following steps: To obtain a sequence in the transmit waveform sequence set, the sequence is constructed by performing the steps of adding K zero elements between two sequences in each sequence set in the sequence family, where K is a positive integer. In a possible design, the transmit waveform sequence set may be: s1=(1,1,1,1,1,1,1,1,0,0,0,0,-1,-1,1,1,-1,-1,1,1,0,0,0,0,-1,1,-1,1,-1,1,-1,1,0,0,0,0,-1,1,1,-1,-1,1,1,-1,0,0,0,0); s2=(-1,-1,1,1,-1,-1,1,1,0,0,0,0,1,1,1,1,1,1,1,1,0,0,0,0,1,-1,-1,1,1,-1,-1,1,0,0,0,0,1,-1,1,-1,1,-1,1,-1,0,0,0,0); s3=(-1,1,-1,1,-1,1,-1,1,0,0,0,0,1,-1,-1,1,1,-1,-1,1,0,0,0,0,1,1,1,1,1,1,1,1,0,0,0,0,1,1,-1,-1,1,1,-1,-1,0,0,0,0); s4=(-1,1,1,-1,-1,1,1,-1,0,0,0,0,1,-1,1,-1,1,-1,1,-1,0,0,0,0,1,1,-1,-1,1,1,-1,-1,0,0,0,0,1,1,1,1,1,1,1,1,0,0,0,0); s5=(1,1,1,1,-1,-1,-1,-1,0,0,0,0,-1,-1,1,1,1,1,-1,-1,0,0,0,0,-1,1,-1,1,1,-1,1,-1,0,0,0,0,-1,1,1,-1,1,-1,-1,1,0,0,0,0); s6=(-1,-1,1,1,1,1,-1,-1,0,0,0,0,1,1,1,1,-1,-1,-1,-1,0,0,0,0,1,-1,-1,1,-1,1,1,-1,0,0,0,0,1,-1,1,-1,-1,1,-1,1,0,0,0,0); s7=(-1,1,-1,1,1,-1,1,-1,1,-1,0,0,0,0,1,-1,-1,1,-1,1,1,-1,0,0,0,0,1,1,1,1,-1,-1,-1,-1,0,0,0,0,1,1,-1,-1,-1,-1,1,0,0,0,0,1,1,-1,-1,-1,1,0,0,0,0); and Includes s8=(-1,1,1,-1,1,-1,-1,1,0,0,0,0,1,-1,1,-1,-1,1,-1,1,0,0,0,0,1,-1,-1,-1,1,-1,1,0,0,0,0,1,1,-1,-1,-1,1,0,0,0,0,1,1,1,1,-1,-1,-1,0,0,0,0).

For example, the technical solutions may be applied to a 4G system or a 5G system, or to another future-oriented new system. This is not limited to the embodiments of the present application. Also, the terms "system" and "network" may be interchangeable.

[0058] Currently, Ipatov sequences have perfect periodic autocorrelation properties, and sequence sets with periodic ZCZ can be generated by cyclic shift. As shown in Figure 2, an Ipatov sequence with a sequence length of 57 is used as the transmit waveform sequence. Because Ipatov sequences have perfect periodic autocorrelation properties, the Ipatov sequence is zero not only in the autocorrelation main lobe but also in the autocorrelation side lobes.

[0059] For example, see Figure 3 for a transmit waveform sequence set. In Figure 3, for any column, the sequences surrounded by two solid lines are Ipatov sequences. The first column is an Ipatov sequence with a sequence length of 57, the second column is a shifted sequence generated by performing a 9-bit cyclic shift on the first column, the third column is a shifted sequence generated by performing a 9-bit cyclic shift on the second column, and so on.

[0060] Furthermore, the transmitting end needs to add a cyclic prefix and a cyclic suffix to each of the two solid line sequences, i.e., add a cyclic prefix before the Ipatov sequence and a cyclic suffix after the Ipatov sequence, and transmit the Ipatov sequence row by row.

[0061] As shown in Figure 3, the transmitting end adds a 12-bit cyclic prefix before the Ipatov sequence and a 12-bit cyclic suffix after the Ipatov sequence. After receiving the corresponding signal, the receiving end correlates the received signal with the local sequence column by column to obtain information about targets within the detection range, i.e., performs a matched filtering operation.

[0062] As shown in Figure 4, the sequence between the two horizontal lines is an Ipatov sequence, with the black box representing element -1, the white box representing element 1, and the striped box representing element 0. The number of Ipatov sequences is six, and the cyclic prefix and cyclic suffix are marked using dashed boxes. Each pulse burst contains six pulses, as shown in the dashed box between the two horizontal lines. The dashed box represents a pulse burst, which contains six pulses: a positive pulse, a negative pulse, a positive pulse, a non-transmitting pulse, a positive pulse, and a positive pulse. The positive pulse corresponds to element 1, the negative pulse corresponds to element -1, and the non-transmitting pulse corresponds to element 0.

[0063] Specifically, the receiving end uses the same sequence as the transmitted waveform sequence set as a local sequence (excluding the cyclic prefix and cyclic suffix) that is set to correlate with the received signal based on the perfect autocorrelation properties of the Ipatov sequence, and can sense information about targets within the detection range based on related information such as peak position. The detection range is half the product of the magnitude of the ZCZ, the repetition period of the pulse burst, and the speed of light.

[0064] Figure 4 shows the matched filtering results for an Ipatov sequence with a sequence length of 57. Using the Ipatov sequence with a sequence length of 57, its shifted sequence, and the corresponding cyclic prefix and cyclic suffix as the transmit waveform sequence set and local sequence set, we can see that three targets within a distance of 297 ns can be effectively distinguished. If the zero correlation zone is 9 and the burst repetition interval (BRI) is 66 ns, then the distance is 0.5 × 9 × 66 = 297 ns. The distance corresponding to 297 ns is determined by the value of 297 ns × c, where c is the speed of light.

[0065] The transmitting end transmits pulse bursts determined by the transmitting waveform sequence set multiple times, and the receiving end can obtain the matched filtering result shown in Figure 4 each time. However, the amplitudes of the three targets mentioned above will change, and then the receiving end can determine information such as the distance and speed of the three targets mentioned above based on the change in amplitude.

[0066] However, to implement the perfect cyclic autocorrelation property characteristic of the Ipatov sequence, the transmitting end needs to add a cyclic prefix before the Ipatov sequence and a cyclic suffix after the Ipatov sequence, which further increases the air interface transmission time.

[0067] In addition, as the sensing distance increases, the zero correlation zone of the required transmitted waveform sequence is correspondingly extended to ensure sensing performance and avoid interference between waveforms. However, extending the zero correlation zone requires an increased number of cyclic shift bits. As shown in FIG. 3, if the number of pulses in each pulse burst is fixed, extending the zero correlation zone requires an increased number of cyclic shift bits. As a result, the length of the transmitted waveform sequence increases, increasing the time required for sensing measurement and causing interference to other devices or applications.

[0068] The present application may be applied to a star topology structure or a peer-to-peer topology structure, as shown in (1) and (2) of Figure 5. In a star topology structure, data communication is performed between a central control node and one or more other devices. In a peer-to-peer topology structure, communication is performed between different devices. Apparatuses and products in embodiments of the present application include, but are not limited to, central control nodes such as communication servers, routers, switches, bridges, computers, or mobile phones, personal area networks (PANs), PAN coordinators, etc. In addition, the present application may also be applied to other application scenarios, which are not limited in the present application.

[0069] Based on this, the present application provides an ultra-wideband-based sensing method to solve the problem that the time required for sensing measurement increases due to the long length of the transmitted waveform sequence. As shown in Figure 6, the method includes the following steps:

[0070] Step 600: The transmitting end determines a transmission waveform sequence set, where the transmission waveform sequence set includes N sequences, where N is a positive integer, and the transmission waveform sequence set includes sequences having aperiodic ZCZ, each sequence having a sequence length of Q, where Q is a positive integer.

[0071] For example, the transmit waveform sequence set may include P sequences, where P≧N and P is a positive integer. In a possible implementation, the transmitting end may select N sequences from the P sequences as the current transmit waveform sequence set based on the capabilities of the transmitting end. For example, the transmit waveform sequence set may include a total of eight sequences, and the transmitting end may select four or six sequences from the eight sequences as the currently used transmit waveform sequence set.

[0072] It will be understood that multiple transmit waveform sequence sets may be pre-configured for the transmitting end and the receiving end, and the transmitting end and the receiving end determine the same transmit waveform sequence set, where the transmit waveform sequence set is one of the multiple transmit waveform sequence sets.

[0073] For example, the transmitting end may negotiate with the receiving end to determine one of a plurality of transmit waveform sequence sets.

[0074] Alternatively, the transmitting end may determine one transmit waveform sequence set from the plurality of transmit waveform sequence sets and send a notification message to the receiving end, where the notification message indicates the transmit waveform sequence set, for example, the notification message includes identification information of the transmit waveform sequence set.

[0075] Alternatively, the transmitting end may determine one transmit waveform sequence set from the multiple transmit waveform sequence sets according to a pre-configured rule, and correspondingly, the receiving end may determine one transmit waveform sequence set from the multiple transmit waveform sequence sets according to the same pre-configured rule, where the transmit waveform sequence set determined by the transmitting end is the same as the transmit waveform sequence set determined by the receiving end.

[0076] Alternatively, the transmitting end and the receiving end may receive instruction information from another device, where the instruction information indicates one of a plurality of transmit waveform sequence sets.

[0077] For example, the sequences included in any transmit waveform sequence set may be determined in a number of ways, including but not limited to the following.

[0078] It should be noted that the transmit waveform sequence set does not have to be constructed by the transmitting end, i.e., the transmitting end determines the transmit waveform sequence set that needs to be currently used, but does not necessarily need to construct the transmit waveform sequence set using the following process. Similarly, the receiving end determines the local sequence set that needs to be currently used, but does not necessarily need to construct the local sequence set using the following process. For example, the transmitting end and the receiving end can obtain multiple transmit waveform sequence sets in advance through pre-configuration or protocol agreement.

[0079] In a possible design of Scheme 1, a transmit waveform sequence set is constructed based on a first matrix, a second matrix, and a third matrix, and the first matrix, the second matrix, and the third matrix are all Hadamard matrices.

[0080] A Hadamard matrix is ​​an nth-order square matrix that contains elements +1 and -1 and satisfies Hn × Hn' = nI, where Hn' is the transpose of Hn and I is a square unit matrix. Hn is a Hadamard matrix of order n, where n is a positive integer greater than or equal to 2.

[0081] For example, the order of the first matrix may be the same as the order of the second matrix, and the order of the third matrix may be the same as or different from the order of the first matrix. The transmit waveform sequence set may be constructed by performing the following steps:

[0082] (1) Based on the first matrix and the third matrix, a sequence set having a sequence length of M(Z+C) is constructed, where M, Z, and C are positive integers, M is the order of the first matrix and the second matrix, Z is the order of the third matrix, and C is a preset value. The sequence set having a sequence length of M(Z+C) includes M×Z sequences.

[0083] For example, to obtain a first processing matrix with sequence number M×s+t, each element in the column with sequence number s of the third matrix is ​​multiplied by the element in the column with sequence number t of the first matrix, and C columns of elements that are all 0 are added, so that the first processing matrix with sequence number M×s+t has M(Z+C) columns, where 0≦s≦Z−1 and 0≦t≦M−1; and to obtain a first sequence with sequence number M×s+t in a sequence set with a sequence length of M(Z+C), the first processing matrix with sequence number M×s+t is output row by row.

[0084] (2) Based on the second matrix and a sequence set with a sequence length of M(Z+C) through n iterations, M n+1 Construct a sequence set with a sequence length of (Z+C). n+1 The sequence set with (Z+C) contains M×Z sequences. n+1 The sequence set having (Z+C) is the transmit waveform sequence set, where n is a positive integer. n+1 The sequence set with (Z+C) contains M×Z sequences, N≦M×Z and P=M×Z, and Q=M n+1 (Z+C).

[0085] An example where n=1 is used. Based on the second matrix and a sequence set with a sequence length of M(Z+C) through one iteration, M 2 A sequence set with a sequence length of (Z+C) is constructed.

[0086] For example, an element having sequence number w in a column having sequence number t in the second matrix is ​​multiplied by the first sequence having sequence number M×s+w to obtain a second matrix to be processed having sequence number M×s+t, where w is from 0 to M−1 and w is a positive integer; 2 To obtain a second sequence having sequence number M×s+t in a sequence set having a sequence length of (Z+C), a second processing target matrix having sequence number M×s+t is output row by row. 2 The sequence set having (Z+C) is the transmit waveform sequence set.

[0087] In the above-mentioned method 1, the number of iterations can be adjusted based on the actual transmission requirements or the capabilities of the transmitting end to determine transmission waveform sequence sets with different sequence lengths.

[0088] For details, please refer to the related description in embodiment 1 below.

[0089] Method 2: A transmit waveform sequence set is constructed based on a sequence family, and the sequence family includes multiple sequence sets, all of which include the same number of sequences, and all of which have the same sequence length.

[0090] A sequence family has two characteristics: Feature 1: For all sequences in any sequence set in a sequence family, the sum of the values ​​of the aperiodic autocorrelation function corresponding to all sequences with a lag τ equal to 0 is the product of the number of sequences and the sequence length, and the sum of the values ​​of the aperiodic autocorrelation function corresponding to all sequences with a lag τ not equal to 0 is 0.

[0091] Feature 2: For all sequence groups determined based on any two sequence sets in the sequence family, each sequence group includes two sequences having the same sequence number, and the sum of the values ​​of the aperiodic cross-correlation function corresponding to all sequence groups respectively with a delay τ equal to 0 is 0, and the sum of the values ​​of the aperiodic cross-correlation function corresponding to all sequence groups respectively with a delay τ not equal to 0 is 0.

[0092] A delay τ equal to 0 indicates a main lobe, and a delay τ not equal to 0 indicates a side lobe.

[0093] Therefore, a sequence family that has the above two characteristics is also called a perfect complement code.

[0098] For example, the transmit waveform sequence set may include the following steps: To obtain a first sequence set of sequences, the first sequence set may be constructed by adding K zero elements between two sequences in each sequence set in the sequence family, where K is a positive integer. Further, to obtain a transmit waveform sequence set, the above operation is performed for all sequence sets.

[0099] The two sequences herein may be two adjacent sequences or two non-adjacent sequences, which is not a limitation in this application.

[0100] Furthermore, in an optional implementation, different numbers of zero elements can be added between adjacent sequences in each sequence set within a sequence family.

[0101] For details, please refer to the related description in embodiment 2 below.

[0102] Step 610: The transmitting end transmits Q pulse bursts to the receiving end based on N sequences, each pulse burst including N pulses, and the jth pulse in the ith pulse burst among the Q pulse bursts corresponds to the ith element in the jth sequence in the transmitting waveform sequence set, where i and j are positive integers, and 1≦i≦Q and 1≦j≦N.

[0103] As shown in FIG. 7, compared to the transmit waveform sequence shown in FIG. 3, the transmit waveform sequence does not include a cyclic prefix or cyclic suffix, and the black box represents element -1, the white box represents element 1, and the striped box represents element 0. Each row of the transmit waveform sequence corresponds to one pulse burst, and the number of pulses contained in each pulse burst is the same as the number of transmitted waveform sequences. The number of transmitted waveform sequences is six. The dashed box in FIG. 7 represents the eighth pulse burst, which includes six pulses: a positive pulse, a negative pulse, a positive pulse, a positive pulse, a positive pulse, and a positive pulse. The positive pulse corresponds to element 1, the negative pulse corresponds to element -1, and the non-transmitted pulse corresponds to element 0. That is, the first pulse in the eighth pulse burst corresponds to the eighth element in the first sequence, the second pulse in the eighth pulse burst corresponds to the eighth element in the second sequence, the third pulse in the eighth pulse burst corresponds to the eighth element in the third sequence, the fourth pulse in the eighth pulse burst corresponds to the eighth element in the fourth sequence, the fifth pulse in the eighth pulse burst corresponds to the eighth element in the fifth sequence, and the sixth pulse in the eighth pulse burst corresponds to the eighth element in the sixth sequence.

[0104] Step 620: The receiving end receives the Q pulse bursts from the transmitting end, and correlates the Q pulse bursts with the local sequence set to determine information about targets within the detection range.

[0105] The local sequence set may also be referred to as the received waveform sequence set. The local sequence set is the same as the transmitted waveform sequence set (when the transmitted waveform sequence set is used as the local sequence set, the local sequence set does not include the cyclic prefix and cyclic suffix).

[0106] For example, the receiving end may correlate the Q pulse bursts with the local sequence set to obtain a matched filtering result, and further determine information about the target within the detection range based on the matched filtering result. The specific implementation in which the Q pulse bursts are correlated with the local sequence set is not limited in this application. For example, the information about the target may include target distance information or target velocity information.

[0107] The detection range is related to the size of the ZCZ and the repetition period of the pulse burst, for example, half the product of the size of the ZCZ, the repetition period of the pulse burst, and the speed of light.

[0108] According to the above method, a transmit waveform sequence set and a receive waveform sequence set corresponding to the transmit end and the receive end, respectively, are designed. The transmit waveform sequence set and the receive waveform sequence set are the same, and all sequences included in the transmit waveform sequence set are sequences in a sequence set including sequences with aperiodic zero correlation zones (ZCZ). Therefore, sequences with aperiodic zero correlation zones (ZCZ) are used, and as a result, cyclic prefixes and cyclic suffixes do not need to be added, thereby shortening the air interface time and improving system performance.

[0109] Embodiment 1 Hadamard matrices are used as basis sequences and an interleaving technique is used to construct a set of transmit waveform sequences.

[0110] The specific process of constructing a transmit waveform sequence set is as follows.

[0111] Step 1: Select two Hadamard matrices of order M and a Hadamard matrix of order Z. The two Hadamard matrices of order M are represented as the first matrix and the second matrix, and the Hadamard matrix of order Z is represented as the third matrix.

[0112] For example, the first matrix is ​​a=[a0,a1,...,a M-1 ], and the second matrix b = [b0, b1, , b M-1 ], and the third matrix h = [h0, h1, , h z-1 ] may also be expressed as

[0113] For example, M=4,

number

number

[0114] The two Hadamard matrices of order M may be the same or different, and the values ​​of M and Z may be the same or different, which is not a limitation in this application. M and Z are positive integers greater than or equal to 2.

[0115] Step 2: Construct a sequence set with a sequence length of M(Z+C). The sequence set with a sequence length of M(Z+C) includes M×Z sequences.

[0116] C is a positive integer. In the following, we will only use C=1 as an example for illustration.

[0117] For example, a specific process for constructing a sequence set having a sequence length M(Z+C) using the interleaving technique is as follows:

[0118] (1) Multiply each element in the column with sequence number s in the third matrix by the element in the column with sequence number t in the first matrix, and add one column of all-zero elements to obtain a first target matrix with sequence number M×s+t. 0≦s≦Z-1, 0≦t≦M-1. The number of columns of 0 can be determined by the value of C. If C=1, the number of columns of 0 is 1.

[0119] (2)

[0120] The number of rows of the third matrix is ​​Z, and the number of columns of the first matrix is ​​M, so Z×M first matrices to be processed can be obtained through the above process, and then Z×M first sequences are obtained;

[0121] For example, M=4,

number

number

[0122] Each element in the first column of h (i.e., the column with sequence number 0) is multiplied by the element in the first column of the first matrix (i.e., the column with sequence number 0), and one column of elements that is all 0 is added to obtain the first matrix to be processed with sequence number 0 (i.e., 4×0+0=0). ++0 --0 --0 --0

[0123] Specifically, the element with sequence number 0 (i.e., +) in the first column of h (i.e., the column with sequence number 0) is multiplied by a0. The element with sequence number 1 (i.e., +) in the first column of h (i.e., the column with sequence number 0) is multiplied by a0.

number

[0124] Each element in the first column of h (i.e., the column with sequence number 0) is multiplied by the element in the second column of the first matrix (i.e., the column with sequence number 1), and one column of elements that is all 0 is added to obtain the first matrix to be processed with sequence number 1 (i.e., 4 × 0 + 1 = 1). --0 ++0 --0 --0

[0125] Each element in the first column of h (i.e., the column with sequence number 0) is multiplied by the element in the third column of the first matrix (i.e., the column with sequence number 2), and one column of elements that is all 0 is added to obtain the first matrix to be processed with sequence number 0 (i.e., 4 × 0 + 2 = 2). --0 --0 ++0 --0

[0126] Each element in the first column of h (i.e., the column with sequence number 0) is multiplied by the element in the fourth column of the first matrix (i.e., the column with sequence number 3), and one column of elements that is all 0 is added to obtain the first matrix to be processed with sequence number 3 (i.e., 4 × 0 + 3 = 3). --0 --0 --0 ++0

[0127] Similarly, each element of the second column of h (i.e., the column with sequence number 1) is multiplied by the element of the first column of the first matrix (i.e., the column with sequence number 1), and one column of elements that are all 0 is added to obtain a first processed matrix with sequence number 4 (i.e., 4×1+0=4), and so on. A first processed matrix with sequence number 5, a first processed matrix with sequence number 6, and a first processed matrix with sequence number 7 may further be obtained. Details will not be described again in this specification.

[0128] Furthermore, the first matrix to be processed having sequence number 0 is the first matrix to be processed having sequence number 0 (i.e., 4(2+1)=12) in the sequence set having sequence length 12 (i.e., 4(2+1)=12).

[0129] For example, the first matrix to be processed having sequence number 1 corresponds to sequence number 1 in the sequence set having sequence length 12 (i.e.

[0132] Similarly, the first processing matrix having sequence number 4, the first processing matrix having sequence number 5, the first processing matrix having sequence number 6, and the first processing matrix having sequence number 7 are the first sequence having sequence number 4, the first sequence having sequence number 5, the first sequence having sequence number 6, and the first sequence having sequence number 7 in the sequence set having sequence length 12, i.e.

[0133] Step 3:M 2 A sequence set with a sequence length of (Z+C) is constructed.

[0134] For example, interleaving techniques can be used to reduce the sequence length M 2 The specific process of constructing a sequence set having (Z+C) is as follows:

[0135] (1) To obtain a second matrix to be processed having a sequence number M×s+t, an element having a sequence number w in a column having a sequence number t in the second matrix is ​​multiplied by a first sequence having a sequence number M×s+w, where w is from 0 to M−1.

[0141] Specifically, the transmit waveform sequence set generated by the above process is as follows:

[0142] The transmit waveform sequence set contains a total of 8 sequences (M × Z = 4 × 2 = 8), and the length of each sequence is 48 (M 2 (Z+1)=4 2(2+1)=48), where each sequence is a sequence with an aperiodic zero correlation zone, and the zero correlation zone is 4. For example, if the transmitting end sends Q pulse bursts to the receiving end based on N sequences, N≦8, P=8, and Q=48.

[0143] Figure 8 shows the transmit waveform sequence set.

[0144] Furthermore, more first sequence sets that meet the requirements can be generated in an iterative manner. For example, if the number of sequences is MZ and the zero correlation zone is M, then M 3 Has a sequence length of (Z+1)

number

[0145] Specifically, the transmit waveform sequence set includes a total of eight sequences, each with a length of 192(M 3 (Z+1)=4 3 (2+1)=192), where each sequence is a sequence with an aperiodic zero correlation zone, and the zero correlation zone is 4. For example, if the transmitting end sends Q pulse bursts to the receiving end based on N sequences, N≦8, P=8, and Q=192.

[0146] Specifically, the transmit waveform sequence set includes:

[0147] Since a plurality of sequences generated using the above-described method and having aperiodic zero correlation zones form a transmit waveform sequence set, no cyclic prefix or cyclic suffix is ​​used, the sensing performance of the transmit waveform sequence set can be guaranteed, and the air interface time can be reduced.

[0148] As another optional transmit waveform sequence set, the method provided in embodiment 1 is used to form a transmit waveform sequence set, where M=8, Z=1, a and b are 8th-order Hadamard matrices, h is a 2nd-order Hadamard matrix, each having a sequence length of 192, and 16 sequences with aperiodic zero correlation zones are obtained, and the zero correlation zone is 8, and M 2 (Z+1)=8 2 (2+1)=192 and M×Z=8×2=16. For example, if a transmitting end transmits Q pulse bursts based on N sequences to a receiving end, N≦16, P=16, and Q=192.

[0153] In this case, the sequence set S={s0,s1,...,s M-1} is a sequence set including sequences with aperiodic ZCZ, where k≦N, and k represents the number of 0s. The number of sequences included in the sequence set S is M, and the sequence length of each sequence is M+(M-1)k. For example, if the transmitting end transmits Q pulse bursts based on N sequences to the receiving end, N≦M, P=M, and Q=M+(M-1)k.

[0154] If k is greater than or equal to the sequence length of the sequences in the sequence set, the zero correlation zone is the sequence length of the sequences plus 1. If k is less than the sequence length of the sequences, the zero correlation zone is k + 1. All sequence sets contain the same number of sequences, and all sequences have the same sequence length. As an example, a CCC with parameters (4,8) is used.

[0157] Since the aforementioned transmit waveform sequence set is used, there is no need to additionally add cyclic prefixes and cyclic suffixes, thereby reducing the air interface time.

For example, when the transmitting end transmits Q pulse bursts to the receiving end based on N sequences, N≦4, P=4, and Q=140. The transmit waveform sequence set specifically includes:

[0161] As another optional transmission waveform sequence set, the method provided in embodiment 2 is used. The transmission waveform sequence set obtained by using a CCC with parameters (4, 26) and k=26 as an example includes a total of four sequences, each having a sequence length of 182, and each sequence includes 78 zero elements, where M+(M-1)k=4×26+(4-1)×26=182, and the zero correlation zone is 27.

[0163] FIG. 8 shows the matched filtering results for a transmit waveform sequence set with a sequence length of 56. Comparing FIG. 3 with FIG. 8, it can be seen that an Ipatov sequence with a sequence length of 57 and a transmit waveform sequence with a sequence length of 56 have the same sensing capability in the distance corresponding to 0 ns to 297 ns. Because the Ipatov sequence uses a cyclic shift structure, very high spurious peaks are generated when the delay is equal to the cyclic shift. However, the transmit waveform sequence set does not have this characteristic. Therefore, the transmit waveform sequence set provided in this application has better sensing performance.

[0164] [Table 1]

[0165] In addition, Table 1 shows that using the transmit waveform sequence set reduces the air interface time by 10% to 20%, and the number of pulses actually transmitted is 4 / 7 of that of the Ipatov sequence. Because the transmit waveform sequence set contains a small number of non-zero elements, the limited power can be concentrated on the actually transmitted pulses to further increase the signal-to-noise ratio, thereby improving the sensing performance.

[0166] 9 is a possible exemplary block diagram of a communication device according to an embodiment of the present application. The device 900 includes a transceiver module 920 and a processing module 910. The transceiver module 920 may include a receiving unit and a transmitting unit. The processing module 910 is configured to control and manage operation of the device 900. The transceiver module 920 is configured to support communication between the device 900 and another network entity. Optionally, the device 900 may further include a storage unit, configured to store program codes and data for the device 900.

[0167] Optionally, each module in the apparatus 900 may be implemented using software.

[0168] Optionally, the processing module 910 may be a processor or controller, such as a general-purpose central processing unit (CPU), a general-purpose processor, a digital signal processing (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA) or another programmable logic device, a transistor logic device, a hardware component, or any combination thereof. The controller / processor may implement or execute various exemplary logic blocks, modules, and circuits described with reference to the contents disclosed in the embodiments of this application. The processor may also be a combination of processors that perform computing functions, such as a combination of one or more microprocessors, or a combination of a DSP and a microprocessor. The transceiver module 920 may be a communication interface, a transceiver, a transceiver circuit, etc. The communication interface is a generic term. In certain implementations, the communication interface may include multiple interfaces. The storage unit may be a memory.

[0169] If the device 900 is a transmitting end or a chip at a transmitting end, the processing module 910 in the device 900 may support the device 900 in performing the transmitting end operations in the above-described example method, for example, may support the device 900 in performing step 600 of FIG. 6 .

[0170] The transceiver module 920 may support the device 900 in communicating with a receiving end. For example, the transceiver module 920 may support the device 900 in performing step 610 of FIG.

[0171] For example, the processing module 910 is configured to determine a transmit waveform sequence set, where the transmit waveform sequence set includes N sequences, where N is a positive integer, and the transmit waveform sequence set includes sequences having aperiodic zero correlation zones ZCZ, and the sequences have a sequence length of Q, where Q is a positive integer. For example, the transceiver module 920 is configured to transmit Q pulse bursts to a receiving end based on the N sequences, where each pulse burst includes N pulses, and the j pulse in the i pulse burst of the Q pulse bursts corresponds to the i element in the j sequence of the N sequences, where i and j are positive integers, and 1≦i≦Q and 1≦j≦N.

[0172] In a possible design, the transmit waveform sequence set includes P sequences, where P≧N and P is a positive integer.

[0173] In a possible design, the transmit waveform sequence set is constructed based on a first matrix, a second matrix, and a third matrix, where the first matrix, the second matrix, and the third matrix are all Hadamard matrices.

[0174] In a possible design, the order of the first matrix is ​​the same as the order of the second matrix. The transmit waveform sequence set may be constructed by the following steps: constructing a sequence set having a sequence length of M(Z+C) based on the first matrix and a third matrix, where M, Z, and C are positive integers, M is the order of the first matrix and the second matrix, Z is the order of the third matrix, and C is a preset value; and constructing a sequence set having a sequence length of M(Z+C) based on the second matrix and the sequence set having a sequence length of M(Z+C) by n iterations. n+1 (Z+C) and constructing a sequence set with sequence length M n+1 The sequence set with (Z+C) contains M×Z sequences, N≦M×Z, and Q=M n+1 (Z+C).

[0175] In a possible design, when a sequence set having a sequence length M(Z+C) is constructed based on the first matrix and the third matrix, each element in the column of sequence number s of the third matrix is ​​multiplied by the element in the column of sequence number t of the first matrix, and C columns of elements that are all 0 are added together to obtain a first processing matrix having sequence number M×s+t, where the first processing matrix having sequence number M×s+t has M(Z+C) columns, where 0≦s≦Z-1 and 0≦t≦M-1; to obtain a first sequence having sequence number M×s+t in the sequence set having a sequence length of M(Z+C), the first processing matrix having sequence number M×s+t is output row by row.

[0176] In a possible design, the sequence length M n+1 When a sequence set having a sequence length M(Z+C) is constructed through n iterations based on the second matrix and a sequence set having a sequence length M(Z+C), 2 A sequence set with (Z+C) is constructed through one iteration based on the second matrix and a sequence set with sequence length M(Z+C).

[0177] In a possible design, M is used to obtain the second matrix to be processed having sequence number M×s+t. 2 When a sequence set having a sequence length of (Z+C) is constructed based on the second matrix and the sequence set having a sequence length of M(Z+C) by one iteration, the element having sequence number w in the column having sequence number t in the second matrix is ​​multiplied by the first sequence having sequence number M×s+w, where w is from 0 to M−1, and w is a positive integer; M 2 To obtain a second sequence having sequence number M×s+t in a sequence set having a sequence length of (Z+C), a second matrix to be processed having sequence number M×s+t is output row by row.

[0178] In a possible design, the transmit waveform sequence set is constructed based on a sequence family, the sequence family including multiple sequence sets, all of which include the same number of sequences and have the same sequence length. For all sequences in any sequence set in the sequence family, the sum of the values ​​of the aperiodic autocorrelation function corresponding to all sequences at a lag τ equal to 0 is the product of the number of sequences and the sequence length, and the sum of the values ​​of the aperiodic autocorrelation function corresponding to all sequences at a lag τ not equal to 0 is 0. For all sequence groups determined based on any two sequence sets in the sequence family, each sequence group includes two sequences having the same sequence number, the sum of the values ​​of the aperiodic cross-correlation function corresponding to all sequence groups at a lag τ equal to 0 is 0, and the sum of the values ​​of the aperiodic cross-correlation function corresponding to all sequence groups at a lag τ not equal to 0 is 0.

[0179] In a possible design, the transmit waveform sequence set is constructed by performing the following steps: add K zero elements between two sequences in each sequence set in the sequence family to obtain sequences in the transmit waveform sequence set, where K is a positive integer.

[0183] For example, N≦4, and Q=56. In a possible design, the transmit waveform sequence set includes:

number

[0184] For example, N≦4, and Q=70. In a possible design, the transmit waveform sequence set includes:

number

[0185] For example, N≦4, and Q=112. In a possible design, the transmit waveform sequence set includes:

number

[0186] For example, N≦4, and Q=140.

[0187] It should be understood that the device 900 according to this embodiment of the present application can correspond to the transmitting end in the aforementioned method embodiments, and the operations and / or functions of the modules in the device 900 are separately configured to implement corresponding steps of the method of the transmitting end in the aforementioned method embodiments. Therefore, the beneficial effects in the aforementioned method embodiments can also be implemented. For the sake of brevity, the details will not be described again in this specification.

[0188] If the device 900 is a receiving end or a chip at a receiving end, the processing module 910 in the device 900 may support the device 900 in performing the receiving end operations in the above-described example method, for example, may support the device 900 in performing step 620 of FIG. 6 .

[0189] The transceiver module 920 may support the device 900 in communicating with the transmitting end. For example, the transceiver module 920 may support the device 900 in performing step 610 of FIG.

[0190] For example, the transceiver module 920 is configured to receive Q pulse bursts from a transmitting end, each pulse burst including N pulses, the jth pulse in the ith pulse burst of the Q pulse bursts corresponds to the ith element in the jth sequence in a transmit waveform sequence set, where i and j are positive integers, the transmit waveform sequence set includes N sequences, where N is a positive integer, the transmit waveform sequence set includes sequences having a non-periodic ZCZ, the sequences have a sequence length of Q, where Q is a positive integer, and 1≦i≦Q and 1≦j≦N. The processing module 910 is configured to correlate the Q pulse bursts with a local sequence set to determine information about targets within a detection range, where the local sequence set is the same as the transmit waveform sequence set, and the detection range is related to the size of the ZCZ and the repetition period of the pulse bursts.

[0191] In a possible design, the detection range is half the product of the size of the ZCZ, the repetition rate of the pulse burst, and the speed of light.

[0192] In a possible design, the information about the target includes target range information or target velocity information.

[0193] In a possible design, the transmit waveform sequence set includes P sequences, where P≧N and P is a positive integer.

[0194] In a possible design, the transmit waveform sequence set is constructed based on a first matrix, a second matrix, and a third matrix, where the first matrix, the second matrix, and the third matrix are all Hadamard matrices.

[0195] In a possible design, the order of the first matrix is ​​the same as the order of the second matrix.

[0196] The transmit waveform sequence set includes the following steps: constructing a sequence set having a sequence length of M(Z+C) based on the first matrix and the third matrix, where M, Z, and C are positive integers, M is the order of the first matrix and the second matrix, Z is the order of the third matrix, and C is a preset value; Based on the second matrix and the sequence set having a sequence length M(Z+C) by n iterations, a sequence set of sequence length M is obtained as a transmit waveform sequence set. n+1 (Z+C) and constructing a sequence set with sequence length M n+1 The sequence set with (Z+C) contains M×Z sequences, N≦M×Z, and Q=M n+1 (Z+C).

[0197] In a possible design, the transmit waveform sequence set is constructed based on a sequence family, where the sequence family includes multiple sequence sets, all of the sequence sets including the same number of sequences, and all of the sequences having the same sequence length.

[0198] For all sequences in any sequence set in a sequence family, the sum of the values ​​of the aperiodic autocorrelation function corresponding to all sequences with a lag τ equal to 0 is the product of the number of sequences and the sequence length, and the sum of the values ​​of the aperiodic autocorrelation function corresponding to all sequences with a lag τ not equal to 0 is 0.

[0199] For all sequence groups determined based on any two sequence sets in the sequence family, each sequence group includes two sequences having the same sequence number, and the sum of the values ​​of the aperiodic cross-correlation function corresponding to all sequence groups respectively with a lag τ equal to 0 is 0, and the sum of the values ​​of the aperiodic cross-correlation function corresponding to all sequence groups respectively with a lag τ not equal to 0 is 0.

[0200] In a possible design, the transmit waveform sequence set may include the following steps: To obtain a sequence in the transmit waveform sequence set, the sequence is constructed by performing the steps of adding K zero elements between two sequences in each sequence set in the sequence family, where K is a positive integer.
