Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a data processing method and related devices. Background Art

[0003] With the development of wireless technology, wireless communication connections can be established between electronic devices through wireless technology, and one electronic device can communicate with another electronic device through the wireless communication connection.

[0004] When electronic devices communicate over wireless connections, they package data into communication frames, modulate these frames using a modem, and then transmit the resulting signal to achieve communication. Currently, electronic devices can use Gaussian frequency shift keying (GFSK) modulation technology to process communication frames with simple hardware design and low power consumption.

[0005] However, the currently used GFSK frame format suffers from shortcomings such as limited transmission rate options, insufficient sensitivity, and poor anti-interference performance. Therefore, it is worth exploring how to design a high-performance GFSK frame format with more transmission rate options when using GFSK modulation technology in electronic devices. Summary of the Invention

[0006] The present application provides a data processing method and related devices, by using this method, electronic devices can obtain a higher performance GFSK frame format and more transmission rate options.

[0007] In a first aspect, the present application provides a data processing method, which includes: a first electronic device generates a first communication frame, which includes a payload and a check field; the first electronic device performs polarization encoding on the payload and the check field in the first communication frame to obtain a second communication frame; the first electronic device performs Gaussian frequency shift keying (GSFK) modulation on the second communication frame to obtain a first modulated signal; the first electronic device sends the first modulated signal to a second electronic device, and the first electronic device establishes a wireless communication connection with the second electronic device.

[0008] Implementing the method provided in the first aspect above enables polar coding of communication frames, generating a high-performance frame structure and improving the reception performance of the communication system. Furthermore, because polar coding offers multiple coding rates, polar coding of communication frames also provides the communication system with a wider range of transmission rate options. Furthermore, using GFSK modulation technology enables electronic devices to modulate and transmit communication frames with simple hardware design and low power consumption.

[0009] In combination with the first aspect, in a possible implementation, the first communication frame also includes a frame header, and the method also includes: the first electronic device performs polarization encoding on the frame header, the payload and the check field in the first communication frame to obtain a third communication frame; the first electronic device performs Gaussian frequency shift keying (GSFK) modulation on the third communication frame to obtain a second modulated signal; the first electronic device sends the second modulated signal to a second electronic device, and the first electronic device establishes a wireless communication connection with the second electronic device.

[0010] In this way, the electronic device can also perform polarization encoding on the frame header, payload, and check field in the communication frame, further improving the receiving performance of the communication system.

[0011] In combination with the first aspect, in a possible implementation method, the first electronic device performs polarization encoding on the payload and the check field in the first communication frame to obtain a second communication frame, specifically including: the first electronic device performs polarization encoding on the payload and the check field in the first communication frame to obtain a fourth communication frame; the first electronic device uses direct sequence spread spectrum technology to perform spread spectrum processing on the payload and check field in the fourth communication frame to obtain the second communication frame.

[0012] In this way, the electronic device first performs polarization encoding on the payload and check field of the communication frame and then performs spread spectrum processing, which can expand the signal bandwidth, improve the receiving performance of the communication system, and enrich the transmission rate options.

[0013] In combination with the first aspect, in a possible implementation method, the first electronic device uses direct sequence spread spectrum technology to spread spectrum the payload and check field in the fourth communication frame to obtain the second communication frame, specifically including: the first electronic device uses direct sequence spread spectrum technology to spread spectrum the payload and check field in the fourth communication frame to obtain a fifth communication frame; the first electronic device inserts a pilot into the payload and check field of the fifth communication frame to obtain the second communication frame.

[0014] After performing polarization coding and spread spectrum processing on the payload and check fields of a communication frame, the electronic device also inserts a pilot signal. This allows the receiving end in the communication system to accurately track the phase and carrier frequency offset of the communication frame using the pilot signal, allowing for more accurate data reception and improving the system's reception performance.

[0015] In combination with the first aspect, in a possible implementation method, the first electronic device uses direct sequence spread spectrum technology to spread spectrum the payload and check field in the fourth communication frame to obtain a fifth communication frame, specifically including: the first electronic device uses direct sequence spread spectrum technology to expand each information bit in the payload and check field in the fourth communication frame into N symbols, where N is a positive integer greater than or equal to 1; or, the first electronic device uses direct sequence spread spectrum technology to expand each A information bits in the payload and check field in the fourth communication frame into B symbols, where A and B are non-negative integers, and A is less than B.

[0016] In this way, the first electronic device can choose from a variety of spread spectrum schemes when performing spread spectrum processing on the payload and check field in the communication frame, thereby improving the adaptability of the first electronic device to different communication environments.

[0017] In combination with the first aspect, in one possible implementation, the first electronic device inserts a pilot into the payload and check field of the fifth communication frame to obtain the second communication frame, specifically including: the first electronic device inserts Y pilots every X symbols in the payload and check field of the fifth communication frame to obtain the second communication frame, where X and Y are non-negative integers.

[0018] In this way, after receiving the signal, the receiving end of the communication system can accurately track the phase and carrier frequency offset of the payload and check field in the communication frame based on the Y pilot signals, receive data more accurately, and improve the receiving performance of the communication system.

[0020] In this way, the electronic device can perform polarization coding and spread spectrum processing on the frame header, payload, and check field in the communication frame, which not only increases the transmission rate options of the communication system, but also improves the receiving performance of the communication system.

[0021] In combination with the first aspect, in a possible implementation method, the first electronic device uses direct sequence spread spectrum technology to spread spectrum the frame header, payload and check field in the sixth communication frame to obtain the third communication frame, specifically including: the first electronic device uses direct sequence spread spectrum technology to spread spectrum the frame header, payload and check field in the sixth communication frame to obtain the seventh communication frame; the first electronic device inserts a pilot into the frame header, payload and check field of the seventh communication frame to obtain the third communication frame.

[0022] In this way, in addition to processing the payload and checksum fields of the communication frame, the first electronic device also performs the same processing on the frame header, providing another GFSK frame structure and enriching the communication system's frame structure options. This makes the electronic device more flexible in selecting communication frame structures and adapts to more complex communication scenarios.

[0023] In combination with the first aspect, in a possible implementation, the first electronic device uses direct sequence spread spectrum technology to perform spread spectrum processing on the frame header, payload and check field in the sixth communication frame, specifically including: the first electronic device uses direct sequence spread spectrum technology to expand each information bit in the frame header, payload and check field in the sixth communication frame into N symbols, where N is a positive integer greater than or equal to 1; or, the first electronic device uses direct sequence spread spectrum technology to expand each A information bits in the frame header, payload and check field in the sixth communication frame into B symbols, where A and B are non-negative integers, and A is less than B.

[0024] In this way, the first electronic device can choose from a variety of spread spectrum schemes when performing spread spectrum processing on the frame header, payload and check field in the communication frame, thereby improving the adaptability of the first electronic device to different communication environments.

[0027] In combination with the first aspect, in a possible implementation manner, the second communication frame or the third communication frame further includes a preamble field and an access address field.

[0028] In this way, the transmitting end and the receiving end in the communication system can be synchronized during communication, thereby improving the receiving performance of the communication system.

[0109] Please refer to FIG. 2 , which exemplarily shows a process in which an electronic device 100 generates a modulation signal.

[0110] As shown in Figure 2, the electronic device 100 can first obtain the specific communication information to be transmitted, convert the communication information into a communication frame, and then modulate the communication frame based on the modem to obtain the above-mentioned modulated signal. Among them, the communication information is the specific information to be sent by the electronic device 100, and the information may include text, pictures, videos, or instructions, etc. The electronic device 100 converts this communication information into a communication frame that the electronic device can recognize. The communication frame is the basic unit for transmitting data in the communication system and is a data packet composed of a series of bits with a specific format and structure.

[0111] The format of the communication frame is determined by the communication protocol or network standard. When the electronic device 100 and the electronic device 200 establish a wireless communication connection based on different communication protocols, the communication frame format generated by the electronic device 100 may be different.

[0112] During the communication between the electronic device 100 and the electronic device 200, if the electronic device 100 generates a communication frame in a certain format, the electronic device 100 can also select Gaussian frequency shift keying (GFSK) modulation technology to modulate the communication frame generated by the electronic device 100 to obtain a modulated signal that can be transmitted.

[0113] It should be understood that GFSK (Gauss Frequency Shift Keying) is a modulation technique commonly used in wireless communications. In GFSK modulation, digital data is converted into a frequency-shifted signal. Electronic devices represent different digital values ​​by varying the carrier frequency offset. For example, a digital signal consists of four levels, corresponding to 00, 01, 10, and 11. During GFSK modulation, the carrier frequency is increased or decreased to produce four different frequencies, each corresponding to the digital signal. Furthermore, before modulation, the electronic device processes the digital signal using a Gaussian low-pass filter.

[0114] Communication frame formats and modulation techniques are not necessarily coupled. In other words, the frame format does not necessarily depend on the modulation technique. The frame format generally refers to the structure and organization of the data frame, including the header, trailer, data field, and checksum. The modulation technique, on the other hand, refers to the method used to convert digital data into an analog signal.

[0115] However, some communication standards or protocols often require that a specific modulation technique be used in conjunction with a frame format to emphasize the combination of modulation technique and frame format used in a specific scenario. Therefore, to more clearly describe a specific communication system or protocol, frame formats and modulation techniques are sometimes associated in naming. For example, GFSK modulation is commonly used in Bluetooth communications. Therefore, the BLE or BLR frame format used in Bluetooth communications might be referred to as the GFSK frame format to emphasize that the frame format is used under GFSK modulation.

[0116] Several common GFSK frame formats are introduced below with reference to FIG. 3A to FIG. 3C .

[0117] FIG3A exemplarily shows a communication frame format, which may be a frame format used when an electronic device communicates via Bluetooth low energy (BLE) technology, hereinafter referred to as a BLE frame format.

[0118] As shown in FIG3A , the BLE frame format may include: a preamble sequence, an access address, a payload, a check field, and an extension field.

[0119] The preamble sequence is generated based on an alternating bit pattern. For example, the preamble sequence can be an 8-bit alternating sequence. The alternating bit pattern of the preamble sequence can depend on the first bit of the access address. If the first bit of the access address is 0, the preamble sequence can be 01010101. If the first bit of the access address is 1, the preamble sequence can be 10101010. During communication, the sender can generate the preamble sequence based on the access address, place it in a communication frame, and send it to the receiver. The receiver can synchronize its clock based on the alternating bit pattern of the preamble sequence in the communication frame, allowing it to correctly interpret the data timing when it first receives data. The alternating bit pattern of the preamble sequence can also be used for frequency synchronization at the receiver. The receiver can adjust its receiving frequency by detecting the frequency characteristics of the preamble sequence to ensure accurate reception of subsequent data. The alternating bit pattern of the preamble sequence can also be used by the receiver for symbol timing estimation. The receiver can estimate the duration of each bit by observing the bit intervals in the preamble sequence, thereby accurately interpreting the timing of subsequent data. The receiver can also configure automatic gain control based on the wireless signal strength of the preamble sequence to adapt to data transmission with different signal strengths.

[0120] The access address can be used to distinguish different BLE communication connections. Each BLE communication connection is assigned a unique access address so that the sender and receiver can correctly identify and distinguish different connections. The access address is also used to synchronize the clock and frequency between communicating devices. Before communication begins, the sender and receiver will synchronize the clock and frequency by exchanging access addresses to ensure correct transmission and reception of data. The access address also includes a specific bit that is used to indicate the type of BLE frame. Based on the bits in the access address, the receiver can determine whether the received communication frame is a broadcast frame, data frame, or control frame, and perform appropriate processing and analysis.

[0121] It should be understood that the access address can be a 32-bit field, in accordance with the BLE protocol specification. Each BLE communication connection will use a different access address to ensure uniqueness and distinction of the connection.

[0122] Payload refers to the actual data carried in the frame.

[0123] The check field can be a check value obtained by the electronic device 100 by calculating the payload, which is used to detect whether the communication frame has errors or damage during the transmission process. Generally, in the BLE frame structure, a cyclic redundancy check (CRC) is usually used as the check field. CRC can usually be a 24-bit check code. The sender generates a CRC check code by calculating the data and attaches the CRC check code to the frame. After receiving the frame, the receiver recalculates the CRC value of the received data and compares it with the CRC value in the frame. If the two do not match, it means that the frame may have an error or damage during transmission.

[0124] The extension field is usually a constant tone extension (CTE) field, which is part of the support for the BLE direction finding function. Specifically, the constant tone extension field is a part of the BLE frame structure and is located at the end of the frame. The CTE field is a fixed-length sequence used to provide additional information required for the direction finding function in BLE communication. The main function of the CTE field is to provide a constant modulated sequence for the processing of the direction finding function. The CTE field length is usually between 16μs and 160μs.

[0125] FIG3B exemplarily shows another communication frame format, which may be a frame format used when an electronic device communicates via Bluetooth long range (BLR) technology, and is hereinafter referred to as a BLR frame format.

[0126] The BLR frame format may include: a preamble, an access address, a rate indication field, a terminator 1, a protocol data unit, and a terminator 2. The functions of the preamble and the access address are basically the same as those in the BLE frame structure, and can be referred to the description in the aforementioned content, which will not be repeated here.

[0127] In addition, the BLR frame format has additional fields such as the rate indicator field, terminator 1, and terminator 2 protocol data unit fields compared to the BLE frame format. The rate indicator (RI) field is used to indicate the coding scheme used for forward error correction coding block 2 (FEC Block 2) described below.

[0128] Terminator 1 (term1) and terminator 2 (term2) are terminators for the Coded PHY layer (Coded PHY), marking the end of Forward Error Correction Block 1 (FEC Block 1) and Forward Error Correction Block 2. Coded PHY uses Forward Error Correction (FEC) technology to improve transmission reliability. FEC Block 1 and FEC Block 2 encode data by dividing it into two blocks. Term 1 can be the terminator of FEC Block 1, and term 2 can be the terminator of FEC Block 2. Term 1 and term 2 can each consist of three bits. The receiver can use term 1 and term 2 to identify the boundaries of FEC Block 1 and FEC Block 2, respectively, for decoding and error correction.

[0129] A protocol data unit (PDU) consists of a header, a payload, and a checksum field. The payload and checksum fields are described above and are not repeated here. The header may include some control information for the frame, such as the start identifier, length, and address information. The receiver can use this header to correctly parse and process the received communication frame.

[0130] Figure 3C exemplarily shows another communication frame format. As shown in Figure 3C, the communication frame can be the wireless frame format 1 of the sparklink low energy (SLE) technology mode. The SLE wireless frame format 1 may include a preamble, an access address, a frame header, a frame header error control, a payload, and a check field. Regarding the preamble, access address, frame header, payload, and check field, reference may be made to the description in the above content, which will not be repeated here. Compared with the above two frame formats, the SLE wireless frame format 1 may also include a header error control (HEC). HEC is a technology for detecting and correcting errors in the communication frame header, and is typically used to ensure reliable transmission and correct parsing of the frame header.

[0131] When electronic device 100 generates communication frames using the three aforementioned communication frame formats, it typically also uses GFSK modulation technology to modulate the communication frames. Therefore, the three aforementioned communication frame formats may also be referred to as GFSK frame formats. In short, the GFSK frame format refers to the format of a specific data frame used under the GFSK modulation technology. This naming convention is primarily intended to accurately describe a specific communication system or protocol.

[0132] Electronic devices can use GFSK modulation technology to process communication frames with low power consumption based on simple hardware design. However, all three GFSK frame formats mentioned above have certain limitations. For example, the preamble length in the BLE frame format can be 8 microseconds, the preamble length in SLE wireless frame format 1 can be 10 microseconds, and the preamble length in the BLR frame format can be 80 microseconds. Because the preambles in the BLE frame format and SLE wireless frame format 1 are shorter, the synchronization time between the sender and receiver before communication is shorter. Therefore, the sensitivity of the BLE frame format and SLE wireless frame format 1 is lower than that of the BLR frame format. In addition, the transmission rate of the BLE frame format and SLE wireless frame format 1 is determined by the bandwidth, resulting in a limited number of transmission rate options.

[0133] Sensitivity refers to the receiver's ability to receive and interpret a specific frame format during communication. A frame structure with superior sensitivity indicates that the receiver can accurately receive and interpret communication frames with that frame structure even under low signal strength or poor channel conditions. Generally, the sensitivity of a communication system is defined as the minimum signal strength at which a receiver in the system can correctly receive and interpret communication frames.

[0134] One of the trade-offs for the BLR frame structure's higher sensitivity is the larger preamble overhead compared to the BLE and SLE wireless frame structures. Furthermore, the BLR frame structure uses convolutional coding for the payload and checksum fields, which only allows for one-half or one-eighth the coding rate. The transmission rate of a communication frame equals bandwidth * coding rate. Therefore, given a fixed bandwidth, the BLR frame structure offers limited transmission rate options. Typically, the BLR frame structure has a bandwidth of 1 MHz, and only two transmission rates are available: 500 kbps and 125 kbps.

[0135] In order to solve the problems existing in the GFSK frame format mentioned above, an embodiment of the present application provides a data processing method. Using this method, an electronic device can generate a higher-performance GFSK frame format. In this method, after the electronic device generates a communication frame of original information, it also performs frame processing on the communication frame. The frame processing may include one or more of polarization coding of the communication frame, spectrum spreading of the communication frame, and inserting a pilot into the communication frame. Only after this, the processed communication frame is modulated using GFSK technology. In this way, the frame structure of the modulated communication frame can be improved, the receiving sensitivity and anti-interference performance of the communication system in which the electronic device is located can be improved, and more transmission rate options can be provided. Reference is made to Figure 4, which exemplarily shows the process of generating a modulated signal by another electronic device 100 provided in an embodiment of the present application.

[0136] As shown in Figure 4, the electronic device 100 can obtain the communication information to be transmitted and generate a communication frame a based on the communication information. After performing the frame processing described above on communication frame a, communication frame b is obtained, and communication frame b is modulated to generate a modulated signal. In this way, the process of processing communication frame a to obtain communication frame b can improve the defects existing in communication frame a. Modulating communication frame b for communication can improve the performance of the communication system. The communication frame a can have the SLE wireless frame format 1 described above, or it can have other frame formats.

[0137] The following is a detailed description of the process of the data processing method with reference to Figure 5 , which exemplarily shows a flow chart of the data processing method.

[0138] As shown in FIG5 , the data processing method may include the following steps S501 to S504 .

[0139] S501. The electronic device 100 generates a communication frame 1.

[0140] The electronic device 100 converts the communication information to be sent to the electronic device 200 into a bit stream to generate a communication frame 1. In one possible implementation, the communication frame 1 may include a payload and a check field. In another possible implementation, the communication frame 1 may include a frame header, a payload, and a check field.

[0141] For example, the format of communication frame 1 may be as shown in FIG6 , where communication frame 1 may include a preamble, an access address, a frame header, a payload, and a checksum field. The functions of the preamble, access address, frame header, payload, and checksum fields may be described in the above description. The present embodiment does not limit the specific content of each field.

[0142] Optionally, the frame format of the communication frame 1 may also be the SLE wireless frame format 1 in the above content.

[0143] S502 . The electronic device 100 performs polarization coding on the payload and check field in the communication frame 1 to obtain a communication frame 2 .

[0144] Polar code is a forward error correction code that has been theoretically proven to reach the Shannon limit. Polarization coding of communication frames can improve the sensitivity and anti-interference performance of communication frames. Polar code also offers flexible coding rates, providing a variety of transmission rate options.

[0145] The core concept of polar coding lies in channel polarization, which involves using coding methods on the coding side to make each subchannel exhibit different reliability. As the code length continues to increase, some channels will tend to become noiseless channels with a capacity close to 1, while other channels will tend to become fully noisy channels with a capacity close to 0. Information is then transmitted directly on channels with a capacity close to 1 to approach the ideal channel capacity. Polar coding is the first coding method theoretically proven to achieve Shannon capacity. It features high performance and low encoding and decoding complexity. At different code lengths, especially for finite codes, Polar codes outperform parallel concatenated convolutional Turbo codes and low-density parity-check (LDPC) codes.

[0146] Polar coding can be implemented by using a generator matrix. For example, FIG. 7A shows a schematic diagram of a polar coding generator matrix.

[0147] The codeword output by the electronic device 100 during polar coding is generally obtained by multiplying the input vector and the generator matrix. The polar coding process performed by the electronic device 100 is x = uG, where x is a binary row vector of length L (i.e., the code length). G is an L-order matrix, which is the polar coding generator matrix mentioned above. u is the polar code codeword generated by the polar coding, also of length L. It should be noted that during the polar coding process, the code length of the generated polar code is generally an integer power of 2. As shown in Figure 7A, the polar code can be formed by a Kronecker product matrix based on the matrix G2.

[0148] If the electronic device 100 wants to generate a length of L=2 m For a polar code with 1 character, the generator matrix to be used is the m-th power Kronecker product of G2. In FIG7A, m is taken as an example. Can be used to generate a length of 2 3 =8 codeword.

[0149] The electronic device 100 can perform polar coding on the bit sequence using a polar coding encoder. Referring to FIG7B , FIG7B exemplarily shows a schematic diagram of a polar coding encoder based on a polar coding generation matrix.

[0150] As shown in Figure 7B, take m = 3 and L = 8 as an example. The input vector u can be an 8-bit vector, the codeword x is also an 8-bit vector, and the generating matrix is ​​an 8-order matrix. The specific form of the generating matrix can refer to the matrix shown in Figure 7A. Among them, the input vector can include information bits and frozen bits. During the polar coding process, the electronic device 100 can calculate the channel capacity corresponding to the input vector 1 to L bits based on the generating matrix G, and select the k positions with the largest channel capacity to transmit k information bits. The information bits can be bits in the communication frame to be polarized coded. The other Lk positions with smaller channel capacity are frozen bits, and the frozen bits are fixed values ​​pre-agreed by the transceiver (such as 0). For example, when L = 8, the input vector can be u = [0, 0, 0, u3, 0, u5, u6, u7]. Among them, the positions u3, u5, u6, and u7 have information bits. Correspondingly, the positions u0, u1, u2, and u4 have frozen bits, and the frozen bits are all set to 0.

[0151] For a specific implementation manner in which the electronic device 100 implements polar coding through a polar encoder, reference may be made to FIG7C , which exemplarily shows an implementation manner of a polar encoder.

[0152] As shown in Figure 7C , using the input vector u with L = 8 as an example, all frozen bits can be set to 0, and the circled "+" sign indicates modulo-2 addition. In the example shown in Figure 7C , an L (L = 8)-bit input vector is formed by k (k = 4) information bits and Lk (Lk = 4) frozen bits. Electronic device 100 performs the operation shown in Figure 7C on the input vector to obtain L coded bits. This form of coding is called polar coding. In Figure 7C , all frozen bits are set to 0. Frozen bits can also be set to other bit values ​​known to both the transmitter and receiver.

[0153] In one possible implementation, the electronic device 100 may perform polarization coding on the payload and check field in the communication frame 1. In this case, the communication frame 1 includes a payload and a check field. The electronic device 100 may perform polarization coding on the payload and the check field separately. For example, if the payload is 1010 and the check field is 11, the electronic device 100 may perform polarization coding on the bit sequences "1010" and "11" separately. The electronic device 100 may also perform polarization coding on the payload and the check field as a whole. For example, the electronic device 100 may directly perform polarization coding on the bit sequence "101011". The description of the payload and the check field here and in the following content is merely a symbolic example used to illustrate the concept of performing polarization coding separately. In actual applications, the payload and polarization coding may also be other bit sequences, the relationship between the payload and the check field may also be in other forms, and the check field may also be included in the payload. This application does not limit the form of the payload and the check field.

[0154] After polarization encoding the payload and check field in communication frame 1, electronic device 100 may further use direct sequence spread spectrum technology to perform spread spectrum processing on the payload and check field in communication frame 1. Spread spectrum processing can improve the signal-to-noise ratio of the communication system and reduce the impact of noise or interference on the signal during communication.

[0155] FIG8 shows a comparison diagram of direct sequence spread spectrum.

[0156] Direct sequence spread spectrum technology is a method of generating spread spectrum signals. By performing spread spectrum processing on the signal, the signal bandwidth can be expanded, making the signal more widely distributed in the frequency domain, thereby improving the anti-interference ability of the communication system.

[0157] In an embodiment of the present application, the electronic device 100 may use the direct sequence spread spectrum technology to perform spread spectrum processing on the communication frame. The electronic device 100 may spread each information bit in the object to be spread into N symbols, where N is a positive integer greater than or equal to 1. For example, when N = 2, the electronic device 100 may spread the bit 0 before spreading to 00 and the bit 1 before spreading to 11. If the spread bit sequence is 1011, the result after spreading is 11001111.

[0158] Alternatively, the electronic device 100 may also use direct sequence spread spectrum technology to spread every A information bits in the spread spectrum object into B symbols, where A and B are both non-negative integers, and A is smaller than B.

[0159] As shown in Figure 8, when A = 4 and B = 16, the results before and after spreading can be referred to in Figure 8. When the bit sequence is 0000, the spreading result can be 0011111000100101. When the bit sequence is 1000, the spreading result can be 0100111110001001. When the bit sequence is 0100, the spreading result can be 0101001111100010. When the bit sequence is 1100, the spreading result can be 1001010011111000. When the bit sequence is 0010, the spreading result can be 0010010100111110. When the bit sequence is 1010, the spreading result can be 1000100101001111. When the bit sequence is 1110, the spreading result can be 1111100010010010100. When the bit sequence is 0001, the spreading result can be 0110101101110000. When the bit sequence is 1001, the spreading result can be 0001101011011100. When the bit sequence is 0101, the spreading result can be 000001101010110111. When the bit sequence is 1101, the spreading result can be 1100000110101101. When the bit sequence is 0011, the spreading result can be 0111000001101011. When the bit sequence is 1011, the spreading result can be 1101110000011010, and when the bit sequence is 0111, the spreading result can be 1011011100000110. When the bit sequence is 1111, the spreading result can be 1010110111000001.

[0160] In one possible implementation, the electronic device 100 may perform spread spectrum processing on the payload and check field separately, or may perform spread spectrum processing on the payload and check field as a whole. For example, if the payload is 1010 and the check field is 11, the electronic device 100 may perform spread spectrum processing on the bit sequences "1010" and "11" separately. The electronic device 100 may also perform spread spectrum processing on the payload and check field as a whole, for example, the electronic device 100 may directly perform spread spectrum processing on the bit sequence "101011". This embodiment of the present application is not limited to this.

[0161] The electronic device 100 may also insert a pilot into the payload and check field of the communication frame 1 after the spread spectrum processing.

[0162] A pilot signal is auxiliary information used to help the receiver identify a signal. It helps the receiver locate the signal's position and direction, enabling more accurate signal identification. Pilot signals are typically embedded in the data, appearing with a certain periodicity or regularity to assist the receiver in signal recovery and demodulation. Generally, the receiver already knows information about the pilot signal inserted into the data before receiving the signal. The receiver can use the pilot signal to accurately track the phase and carrier frequency offset of the received signal.

[0163] FIG9 is a schematic diagram showing the insertion of pilots into a communication frame.

[0164] As shown in Figure 9, electronic device 100 can insert Y pilots every X symbols in the object where the pilots are to be inserted. The inserted pilots are sequences known to both the transmitter and receiver, can be set by the transmitter, and can include different sequences. For example, in the above-mentioned communication system 300, when X = 8 and Y = 3, electronic device 100 can set the pilots to alternate between 000 and 111. If the bit sequence before the pilots are inserted is 01010010100001110100, the sequence after the pilots are inserted can be 01010010000100001111110100.

[0165] In one possible implementation, the electronic device 100 may insert pilots into the payload and check fields separately, or insert the pilots into the payload and check fields as a whole. For example, if the payload is 11110000 and the check field is 1111, the electronic device 100 may insert pilots into the sequences "11110000" and "1111" separately, or into the sequence "111100001111." This is not limited in this embodiment of the present application.

[0166] In another possible implementation, the electronic device 100 may perform polar coding on the frame header, payload, and check field in the communication frame 1. In this case, the communication frame 1 includes the frame header, payload, and check field.

[0167] Similarly, the electronic device 100 may also perform spread spectrum processing and pilot insertion on the polarization-encoded communication frame 1 in sequence, and the operation objects may be the frame header, payload, and check field in the communication frame 1.

[0168] In one possible implementation, the electronic device 100 may perform the polarization coding, spreading processing, and pilot insertion on the frame header, payload, and check field separately, or may perform polarization coding, spreading processing, and pilot insertion on the frame header, payload, and check field as a whole. This embodiment of the present application is not limited to this.

[0169] That is, the electronic device 100 may perform polarization coding on some fields in the communication frame 1. After polarization coding, the electronic device 100 may further perform spread spectrum processing on these fields. After spread spectrum processing, the electronic device 100 may further perform pilot insertion processing on these fields. These fields may be the payload and check fields in the communication frame 1, or may be the frame header, payload, and check fields in the communication frame 1. The premise for these fields to be the payload and check fields is that the communication frame 1 includes the payload and check fields. The premise for these fields to be the frame header, payload, and check fields is that the communication frame 1 includes the frame header, payload, and check fields.

[0170] S503 . The electronic device 100 performs Gaussian frequency shift keying (GFSK) modulation on the communication frame 2 to obtain a modulated signal 1 .

[0171] S504 . The electronic device 100 sends the modulated signal 1 to the electronic device 200 .

[0172] After the electronic device 100 obtains the communication frame 2 through steps S501 and S502, the communication frame 2 has a higher performance GFSK frame format. The electronic device 100 modulates the communication frame 2 into a modulation signal 1 using the GFSK modulation technique, and can transmit the information to the electronic device 200.

[0173] FIG10 exemplarily shows another flow chart of the data processing method.

[0174] As shown in FIG10 , the data processing method may further include the following steps S1001 to S1004 .

[0175] S1001. The electronic device 100 generates a communication frame 3.

[0176] In one possible implementation, the communication frame 3 may include a payload and a check field. In another possible implementation, the communication frame 3 may include a frame header, a payload, and a check field.

[0177] Exemplarily, the frame format of the communication frame 3 can be the same as the frame format of the above-mentioned communication frame 1, or it can be the same as the SLE wireless frame format 1 in the above-mentioned content. The embodiment of the present application does not limit the specific content of each field in the communication frame 3.

[0178] S1002. The electronic device 100 inserts a pilot signal into the payload and check field in the communication frame 3 to obtain a communication frame 4.

[0179] In a possible implementation, the electronic device 100 may insert a pilot into the payload and check fields in the communication frame 3 .

[0180] Before inserting the pilot, the electronic device 100 may also perform polarization coding on the payload and check field in the communication frame 3. Alternatively, the electronic device 100 may also perform spread spectrum processing on the payload and check field in the communication frame 3.

[0181] That is, the electronic device 100 can insert pilot signals into the payload and check fields in the communication frame 3 separately, or can first perform polarization encoding on the payload and check fields and then insert pilot signals, or can first perform spread spectrum processing on the payload and check fields and then insert pilot signals.

[0182] In another possible implementation manner, the electronic device 100 may insert a pilot into the frame header, payload, and check field in the communication frame 3 .

[0183] Before inserting the pilot into the frame header, payload, and check field, the electronic device 100 may also perform polarization coding or spread spectrum processing. The specific combination of technical means can refer to the above-mentioned processing of the payload and check field, which is not repeated here.

[0184] S1003. The electronic device 100 performs Gaussian frequency shift keying (GFSK) modulation on the communication frame 4 to obtain a modulated signal 2.

[0185] S1004 . The electronic device 100 sends the modulated signal 2 to the electronic device 200 .

[0186] Step S1003 and step S1004 may refer to the description of the above-mentioned step S503 and step S504, which will not be repeated here.

[0187] Implementing the methods provided in the embodiments of this application enables electronic devices to generate higher-performance GFSK frame formats, improving the reception performance of communication systems. It also enables electronic devices to select a wider range of transmission rates, increasing the flexibility of the communication system and enhancing its ability to cope with diverse communication environments and meet different communication needs.

[0188] In the embodiments of the present application, communication frame 1 may be referred to as the first communication frame. Communication frame 2 may be referred to as the second communication frame, or the third communication frame. Communication frame 3 may be referred to as the eighth communication frame.
