Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to an information bit modulation method, demodulation method, device, and storage medium. Background Technology

[0002] Currently, the modulation methods supported by communication systems mainly include Pulse Amplitude Modulation (PAM) and Pulse Position Modulation (PPM). PAM is a modulation method where the amplitude of the pulse carrier varies with the baseband signal, essentially modulating the information bits to the pulse amplitude. PPM, on the other hand, is a modulation method where the position of the pulse carrier varies with the baseband signal, essentially modulating the information bits to the pulse position. Because PAM only modulates the information bits to the pulse amplitude, while PPM only modulates them to the pulse position, the bandwidth utilization of information bit modulation is relatively low.

[0038] The following description, in conjunction with the accompanying drawings, details an information bit modulation method, demodulation method, device, and storage medium provided in this application through some embodiments and application scenarios.

[0039] In this embodiment, the sending end is a terminal and the receiving end is a network-side device, or the sending end is a network-side device and the receiving end is a terminal, or the sending end is a terminal and the receiving end is a terminal, or the sending end is a network-side device and the receiving end is a network-side device.

[0040] In this application embodiment, the communication methods between the transmitting end and the receiving end include, but are not limited to, backscatter communication, laser communication, wireless optical communication, visible light communication, etc. Specifically, they can be applied to many communication systems such as intensity modulation-direct detection (IM-DD) communication systems, cellular systems, Wi-Fi systems, sidelink systems, wireless optical communication systems, and backscatter communication systems.

[0041] Please see Figure 2 , Figure 2 This is a flowchart of an information bit modulation method provided in an embodiment of this application, such as... Figure 2 As shown, it includes the following steps:

[0042] Step 201: The transmitting end modulates the information bits to the number of pulses, the arrangement of pulse positions, and the pulse amplitude to generate the corresponding modulation symbols.

[0043] In this embodiment, modulating the information bits onto the number of pulses, the arrangement of pulse positions, and the pulse amplitude can also be understood as mapping the information bits onto the number of pulses, the arrangement of pulse positions, and the pulse amplitude, respectively. This achieves modulation of the information bits in three dimensions: the number of pulses, the arrangement of pulse positions, and the pulse amplitude. For example, the three parts of the information bits are modulated onto the number of pulses, the arrangement of pulse positions, and the pulse amplitude, respectively.

[0044] In one implementation, information bits are mapped step-by-step to the number of pulses, the arrangement of pulse positions, and the pulse amplitude. Specifically, the transmitting end generates or determines the information bits and divides them into three parts: the first part is mapped to the number of pulses, the second part is mapped to the arrangement of pulse positions, and the third part is mapped to the pulse amplitude.

[0045] In another implementation, the aforementioned information bits can be directly mapped to the number of pulses, the arrangement of pulse positions, and the pulse amplitude.

[0046] It should be noted that, in the embodiments of this application, the mapping method between information bits and pulse number, pulse position arrangement and combination and pulse amplitude is not limited. In addition to step mapping and direct mapping, other mapping methods are also possible.

[0047] The above-mentioned number of pulses can represent the number of pulses within a time-domain resource unit, the above-mentioned pulse position arrangement can represent the position arrangement of pulses within a time-domain resource unit, and the above-mentioned pulse amplitude can represent the amplitude of pulses within a time-domain resource unit.

[0048] In this embodiment of the application, the modulation method of modulating information bits to the number of pulses, the arrangement of pulse positions, and the pulse amplitude can be called flexible multiple pulse amplitude position modulation (F-MPAPM).

[0049] It should be noted that, in the embodiments of this application, modulating the information bits to the number of pulses, the arrangement of pulse positions and the pulse amplitude to generate the corresponding modulation symbol can also be understood as using a first modulation to modulate the information bits and generate the modulation symbol, wherein the first modulation is a modulation method based on the number of pulses, the pulse position and the pulse amplitude.

[0050] Step 202: The transmitting end transmits the modulation symbol.

[0051] The aforementioned transmitting end may transmit the modulation symbols directly, or it may add other information after the symbols are modulated before transmission, or it may transmit after performing other signal processing; there is no limitation on this.

[0052] In this embodiment of the application, the above steps can be used to modulate information bits to the number of pulses, the arrangement and combination of pulse positions, and the pulse amplitude, thereby improving the bandwidth utilization of information bit modulation. Furthermore, since more information bits are modulated at once, high power efficiency modulation can also be achieved.

[0053] As an optional implementation, within a first time-domain resource unit, the number of pulses carries log2n bits of the information bits, and the arrangement of pulse positions carries the information bits of... The pulse amplitude carries n·log2L bits of the information bits;

[0054] Where n is the number of pulses of the modulation symbol within a first time-domain resource unit, L is the amplitude modulation order supported by each pulse, M is the number of second time-domain resource units included in a first time-domain resource unit, and n, L and M are positive integers.

[0055] The aforementioned first time-domain resource unit can be a frame, subframe, or time slot, etc., and the aforementioned second time-domain resource unit can be a subframe, time slot, sub-time slot, or symbol, etc. The phrase "the pulse amplitude carries n·log2L bits of the information bits" means that the pulse amplitude of n pulses within a first time-domain resource unit can carry n·log2L bits, i.e., one pulse can carry log2L bits.

[0056] The following example illustrates the concept of using the first time-domain resource unit as a frame and the second time-domain resource unit as a time slot:

[0057] The number of pulses in each frame can be flexibly designed, making the number of pulses in each frame variable. Therefore, the pulse count information can be used for bit information mapping. If we limit a frame to M time slots and at most n (1 ≤ n ≤ M) pulses, then the number of pulses i ∈ {1, 2, ..., n} in a frame can represent log₂n bits. If n = M, then the number of pulses i (1 ≤ i ≤ M) in each frame can itself represent log₂M bits.

[0058] Based on the above, it is determined that there are n pulses in M ​​time slots within a frame. By designing the relative positional arrangement of these n pulses, each pulse positional arrangement can be used to carry information bits.

[0059] Based on the above, it is determined that there are n pulses in M ​​time slots within a frame. By designing the relative positional arrangement of these n pulses, each pulse positional arrangement can be used to carry information bits.

[0060] For example: If n pulses are transmitted in M ​​time slots, the number of possible permutations and combinations is .

[0061] In this way, the pulse position arrangement and combination of n pulses in each frame can carry... 1 bit.

[0062] Building upon the above, further information bits can be carried by controlling the amplitude of the n pulses within a frame. Assuming each pulse supports L-order amplitude modulation, the amplitude of each pulse can carry log₂L bits, and the amplitude information of the n pulses within each frame can carry n·log₂L bits.

[0063] In this embodiment, the number, positional arrangement, and amplitude of the aforementioned n pulses can be used to carry within a first time-domain resource unit. This improves bandwidth utilization and modulation efficiency.

[0064] As an optional implementation, the transmitting end modulates the information bits to the number of pulses, the arrangement of pulse positions, and the pulse amplitude, including:

[0065] The transmitting end modulates the first portion of the information bits onto the number of pulses;

[0066] The transmitting end modulates the second part of the information bits to the pulse position and arranges them accordingly;

[0067] The transmitting end modulates the third part of the information bits onto the pulse amplitude.

[0068] Wherein, the first, second, and third parts of bits mentioned above can be modulated sequentially to the number of pulses, the arrangement of pulse positions, and the pulse amplitude; or, the first, second, and third parts of bits mentioned above can be symbolically mapped to the direct mapping relationship between control information bits and {number of pulses, arrangement of pulse positions, and pulse amplitude}. For example: Figure 3 For example, a frame consists of 8 time slots, i.e., M=8. The first frame contains 3 pulses with amplitude orders of 1, 4, and 3 respectively. Thus, the number of pulses in the first frame is 3. The 11th phase position of these 3 pulses within the 8 time slots represents the 56 possible relative position combinations of the 3 pulses. Therefore, for the first frame, the information bits can be directly mapped according to the direct mapping relationship with {3, 11, {1, 4, 3}}.

[0069] In this embodiment, the first part of the information bits, the second part of the bits, and the third part of the bits can be modulated sequentially to the number of pulses, the arrangement of pulse positions, and the pulse amplitude.

[0070] As an optional implementation, the number of pulses of the modulation symbol is the number of pulses within a first time-domain resource unit;

[0071] The pulse position arrangement of the modulation symbol is a combination of the pulse positions within a first time-domain resource unit.

[0072] The pulse amplitude of the modulation symbol is the amplitude of each pulse within a first time-domain resource unit.

[0073] Or with Figure 3For example, the first frame has 3 pulses, which is the 11th phase position of the 56 relative position combinations of a single pulse within 8 time slots, i.e., position combination is represented as 11, and pulse amplitude is represented as 1, 4, 3; the second frame has 1 pulse, which is the 5th phase position of the 8 relative position combinations of a single pulse within 8 time slots, i.e., position combination is represented as 5, and pulse amplitude is represented as 2; the third frame has 2 pulses, which is the 12th relative position of the 28 relative position combinations of two pulses within 8 time slots, i.e., position combination is represented as 12, and pulse amplitude is represented as 4, 1.

[0074] As an optional implementation, the method further includes:

[0075] The sending end sends indication information, which is used to indicate at least one of the following:

[0076] The number of second time-domain resource units within a first time-domain resource unit;

[0077] The maximum number of pulses within a first-time-domain resource unit;

[0078] The amplitude modulation order supported by the pulse.

[0079] Of these, at least one of the above three items can be defined by the protocol or configured on the network side, or the receiving end can be notified through the above indication information.

[0080] The above instructions can be contained in one of the following:

[0081] Downlink Control Information (DCI), Sidelink Control Information (SCI), and PHY preamble in Wi-Fi physical frames.

[0082] This implementation allows the transmitting end to send a signal modulated by F-MPAPM to the receiving end, and to inform the receiving end of the modulation method information it uses through an indication message, so that the receiving end can demodulate according to the indication. For example, the receiving end receives the signal modulated by F-MPAPM and the indication message, and demodulates according to the indication message.

[0083] Of course, in some embodiments, the content indicated by the above-mentioned indication information may be negotiated in advance by the receiving end and the sending end, or defined by a protocol, etc.

[0084] As an optional implementation, the transmitting end transmits the modulation symbol, including:

[0085] The transmitting end performs signal processing on the modulation symbol to obtain the transmitted signal;

[0086] The transmitting end transmits the transmission signal.

[0087] The above signal processing includes, but is not limited to, inserting at least one of the following:

[0088] Synchronization sequence, pilot sequence.

[0089] This implementation allows the transmitter to add a synchronization header, pilot signal, and other signal processing elements after F-MPAPM signal modulation before sending the signal out, thereby improving signal transmission performance.

[0090] In this embodiment, the transmitting end modulates the information bits to the number of pulses, the arrangement of pulse positions, and the pulse amplitude to generate corresponding modulation symbols; the transmitting end then transmits the modulation symbols. This supports modulating information bits to the number of pulses, the arrangement of pulse positions, and the pulse amplitude, thereby improving the bandwidth utilization of information bit modulation.

[0091] Please see Figure 4 , Figure 4 This is a flowchart of an information bit demodulation method provided in an embodiment of this application, such as... Figure 4 As shown, it includes the following steps:

[0092] Step 401: The receiving end acquires the transmitted signal and obtains the modulation symbol based on the transmitted signal.

[0093] The above-mentioned modulation symbols can be obtained by the receiver completing at least one of the following signal processing steps: system synchronization, channel estimation, channel equalization, etc.

[0094] Step 402: The receiving end performs demodulation according to the number of pulses, the arrangement and combination of pulse positions, and the mapping relationship between pulse amplitude and information bits of the modulation symbol to obtain information bits.

[0095] The demodulation described above can be coherent demodulation or non-coherent demodulation. For example, in non-coherent demodulation, the number, position, and amplitude of the modulation symbol pulses can be obtained by detecting the corresponding resources. For example, by statistically analyzing the average power of the received signal in each time slot of the corresponding frame, the average power information of the corresponding pulse in each time slot can be obtained, and thus the number, position, and amplitude of the modulation symbol pulses can be obtained.

[0096] The demodulation described above, based on the mapping relationship between the number of pulses, the arrangement of pulse positions, and the pulse amplitude of the modulation symbol and the information bits, can be performed according to the mapping relationship between the number of pulses and the information bits, the mapping relationship between the arrangement of pulse positions and the information bits, and the mapping relationship between the pulse amplitude and the information bits. Alternatively, information bit demodulation can be performed according to the mapping relationship between {number of pulses, relative arrangement of pulse positions, pulse amplitude} and the information bit stream. Specifically, the demodulation method is not limited in the embodiments of this application. For example, demodulation can also be performed according to other mapping relationships between information bits and symbols. Furthermore, the receiving end can specifically perform signal demodulation based on coherent demodulation or non-coherent demodulation.

[0097] Optionally, within a first time-domain resource unit, the number of pulses carries log2n bits of the information bits, and the arrangement of pulse positions carries the information bits of... The pulse amplitude carries n·log2L bits of the information bits;

[0098] Where n is the number of pulses of the modulation symbol within a first time-domain resource unit, L is the amplitude modulation order supported by each pulse, M is the number of second time-domain resource units included in a first time-domain resource unit, and n, L and M are positive integers.

[0099] Optionally, the receiving end performs demodulation according to the number of pulses, the arrangement and combination of pulse positions, and the mapping relationship between pulse amplitude and information bits of the modulation symbol to obtain information bits, including:

[0100] The receiving end demodulates the first part of the information bits according to the mapping relationship between the number of pulses of the modulation symbol and the information bits;

[0101] The receiving end demodulates the second part of the information bits according to the mapping relationship between the pulse position arrangement and combination of the modulation symbols and the information bits;

[0102] The receiving end demodulates the third part of the information bits according to the mapping relationship between the pulse amplitude of the modulation symbol and the information bits.

[0103] For example, given a frame with M time slots and a maximum of M pulses allowed, if the number of pulses in a frame is n, then the corresponding log2M information bits are demodulated according to a preset modulation rule. For instance, for an F-MPAPM signal with 8 time slots in a frame, if there are 2 pulses in that frame, the corresponding information bit is "001". Similarly, if there are 3 or 6 pulses, the mapped information bits are "010" or "101" respectively, thus obtaining the first part of the bits mentioned above.

[0104] Furthermore, based on the arrangement and combination of the positions of these n pulses within the frame, i.e., their relative positions within the frame, the corresponding pulses are demodulated according to a preset modulation rule. This yields one information bit, which is the second part of the bits mentioned above.

[0105] Furthermore, based on the amplitude of each of these n pulses, demodulation is performed by comparing it with preset (L-1) amplitude thresholds, thereby demodulating the corresponding n·log2L information bits to obtain the aforementioned third part of the bits.

[0106] Optionally, the number of pulses of the modulation symbol is the number of pulses within a first time-domain resource unit;

[0107] The pulse position arrangement of the modulation symbol is a combination of the pulse positions within a first time-domain resource unit.

[0108] The pulse amplitude of the modulation symbol is the amplitude of each pulse within a first time-domain resource unit.

[0109] Optionally, the method further includes:

[0110] The receiving end receives indication information, which indicates at least one of the following:

[0111] The number of second time-domain resource units within a first time-domain resource unit;

[0112] The maximum number of pulses within a first-time-domain resource unit;

[0113] The amplitude modulation order supported by the pulse;

[0114] The receiving end performs demodulation according to the number of pulses, the arrangement of pulse positions, and the mapping relationship between pulse amplitude and information bits of the modulation symbol, including:

[0115] The receiving end performs demodulation according to the indication information, based on the number of pulses of the modulation symbol, the arrangement and combination of pulse positions, and the mapping relationship between pulse amplitude and information bits.

[0116] Optionally, the indication information is carried in one of the following:

[0117] Preambles in DCI, SCI, and Wi-Fi physical frames.

[0118] It should be noted that this embodiment is used as a reference for... Figure 2 The implementation methods of the corresponding receiving end in the illustrated embodiments can be found in the following examples. Figure 2 To avoid repetition, the relevant descriptions of the embodiments shown will not be repeated in this embodiment.

[0119] The methods provided in this application are illustrated below through two examples:

[0120] Example 1

[0121] In this embodiment, we take the example of M time slots per frame, a maximum of n pulses per frame, and each pulse supporting L-order PAM modulation.

[0122] like Figure 3 As shown, Figure 3 The modulation scenario shown is an F(8,4) pulse 8-PPM-4PAM, where F(8,4) means that there are 8 time slots within the frame and a maximum of 4 pulses, i.e., the number of pulses can be n = {1,2,3,4}. The transmitting end modulates the signal as follows:

[0123] (1) First, the bit stream to be modulated is divided into three parts according to the modulated dimension of F(8,4)pulse 8-PPM-4PAM, which are respectively used to carry the number of pulses, the pulse arrangement and combination and the pulse amplitude in each frame.

[0124] (2) Next, the bit-to-symbol mapping process is performed. According to the modulatorable dimension of F(8,4)pulse 8-PPM-4PAM, the bit-to-symbol mapping can also be divided into the following three steps (the order of the steps is not important; this is only for illustrative purposes). Figure 3 Take the first frame in the video as an example:

[0125] (I) Since a maximum of 4 pulses can be sent in each frame, the number of pulses to be sent in a frame can be randomly selected as n = {1, 2, 3, 4}. In the first frame, n = 3 pulses are selected, which can carry log24 = 2 bits. Therefore, the 2 information bits in the bit stream can be mapped to the number of pulses 3 as the first part of the information bits;

[0126] (II) After determining that three pulses can be transmitted within this frame, since the relative positions of these three pulses in the eight time slots of this frame can also be randomly selected, this can constitute... There are 32 possible arrangements of relative positions, so each arrangement can carry log256 = 5.8 information bits. Since it is impossible to map a fraction of these bits, 0.8 information bits can be discarded, and only 5 information bits are transmitted, corresponding to 32 possible arrangements of relative positions. This embodiment does not limit how to select the optimal arrangement, i.e., choosing 32 arrangements from 56 arrangements, and will not elaborate further here. Therefore, the 5 information bits in the bitstream can be used as the second part of the information bits and mapped to the 32 possible arrangements of phase positions of these 3 pulses;

[0127] (III) After determining the relative positions of these three pulses, since each pulse supports 4th-order PAM modulation, information bits are carried by controlling the amplitude of each pulse. Taking 4PAM as an example, there are four pulse amplitudes. The mapping relationship between information bits and pulse amplitudes can be: "00" - first-order amplitude; "01" - second-order amplitude; "11" - third-order amplitude; "10" - fourth-order amplitude. It should be noted that this is only for illustrative purposes and does not restrict the mapping relationship between information bits and pulse amplitudes. Therefore, the six information bits in the bitstream can be mapped as the third part of the information bits to the 4th-order amplitudes of these three pulses respectively.

[0128] (3) After completing the F(8,4)pulse 8-PPM-4PAM symbol modulation, the transmitting end can also transmit the signal after signal processing such as inserting synchronization sequence and pilot sequence.

[0129] (4) Furthermore, the transmitting end needs to inform the receiving end of the modulation-related indication information of F(8,4)pulse 8-PPM-4PAM, and the indication information shall include at least one of the following:

[0130] The number of time slots M in a frame is the PPM modulation order, which is 8 in the example;

[0131] The maximum number of pulses n allowed within a sequence is 4 in this example;

[0132] The amplitude modulation order L supported by the pulse is 4 in this example.

[0133] It should be noted that the above-mentioned indication information is carried in different signaling in different communication systems. For example, if the modulation method is applied to a cellular system, the indication information is carried through DCI; if the modulation method is applied to a sidelink system, the indication information is carried through SCI; and if the modulation method is applied to a WiFi system, the indication information is carried through the preamble in the PPDU.

[0134] After completing signal processing such as symbol synchronization, channel estimation, and channel equalization, the receiver performs F(8,4)pulse 8-PPM-4PAM demodulation according to the received instruction information to obtain the information bits. For details of the demodulation process, please refer to [link to documentation]. Figure 4 The embodiments shown are not described in detail here.

[0135] Example 2

[0136] In this embodiment, we will also use the example of M time slots per frame, a maximum of n pulses per frame, and each pulse supporting L-order PAM modulation.

[0137] This embodiment differs from Embodiment 1 in the following ways:

[0138] The bit stream to be modulated is divided into three parts. The first part of the bit stream is mapped to the number dimension of multiple pulses; the second part of the bit stream is mapped to the arrangement and combination of the relative positions of multiple pulses; and the third part of the bit stream is mapped to the amplitude dimension of the pulses. Through a certain bit-symbol mapping relationship, F-MPAPM modulation is realized.

[0139] In this embodiment, the bitstream to be modulated can be symbol-mapped according to the direct mapping relationship between information bits and {number of pulses, relative position arrangement of pulses, and amplitude of pulses} to achieve F-MPAPM modulation. Similarly, using... Figure 3 The following example illustrates the F(8,4)pulse 8-PPM-4PAM:

[0140] The transceiver first determines that F(8,4)pulse 8-PPM-4PAM modulation will be used. Next, bit-to-symbol mapping is performed. According to the modulatorable dimensions of F(8,4)pulse 8-PPM-4PAM, the bit stream to be modulated can also be symbol-mapped according to the direct mapping relationship between information bits and {number of pulses, relative position arrangement of pulses, and pulse amplitude}. Figure 3 Taking the first frame as an example, the bits to be modulated are symbolically mapped according to the direct mapping relationship with {3,11,{1,4,3}}. Here, 3 represents the 3 pulses transmitted within this frame, carrying 2 bits. 11 is the sequence number of the pulse relative position arrangement pattern preset by the transceiver, indicating the 11th phase position among the 56 possible relative position arrangements of the 3 pulses within 8 time slots. {1,4,3} represents the pulse amplitude of these three pulses.

[0141] After completing the F(8,4)pulse 8-PPM-4PAM symbol modulation, the other signal processing and indication information are similar to those in Embodiment 1 of the present invention, and will not be repeated here.

[0142] In this embodiment of the application, the following can be achieved:

[0143] Information bits are carried through three dimensions: the number of multiple pulses, the arrangement and combination of multiple pulse phase positions, and the pulse amplitude. F-MPAPM modulation is achieved through a certain bit-symbol mapping relationship.

[0144] The bits to be modulated and symbols can be mapped in stages, directly mapped, or other mapping relationships to achieve F-MPAPM modulation;

[0145] The transmitting end can inform the receiving end of F-MPAPM modulation-related indication information, which is used to instruct the receiving end to use F-MPAPM symbol demodulation.

[0146] In this embodiment, information modulation is achieved by making full use of the three dimensions of pulse number, relative position arrangement and combination of pulses and pulse amplitude of multi-pulse amplitude modulation (F-MPAPM), thereby achieving signal modulation with higher bandwidth utilization while ensuring average power efficiency.
