Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a data processing method and related devices. Background Art

[0002] With the development of wireless technologies, wireless communication connections can be established between electronic devices through wireless technologies, and one electronic device can communicate with another electronic device through the wireless communication connection.

[0003] During the process of communication between electronic devices through a wireless communication connection, data needs to be packaged into communication frames and the communication frames are modulated using a modem, and then the modulated signals are sent out to achieve communication. Currently, based on a simple hardware design, electronic devices can use Gaussian Frequency Shift Keying (GFSK) modulation technology to process communication frames with low power consumption.

[0004] However, the currently used GFSK frame format has disadvantages such as few transmission rate options, insufficient sensitivity, and anti-interference performance. Therefore, how to design a GFSK frame format with high performance and more transmission rate options when electronic devices use GFSK modulation technology is a problem worthy of discussion.

[0007] Implementing the method provided in the first aspect above can perform polar coding on communication frames, can generate a frame structure with high performance, and improve the receiving performance of the communication system. Moreover, since there are many coding rates for polar coding, performing polar coding on communication frames can also enable the communication system to have more transmission rate options.

[0106] During the process of communication between the electronic device 100 and the electronic device 200 via a wireless communication connection, when the electronic device 100 wants to send a message to the electronic device 200, the electronic device 100 can first obtain the specific data to be sent, then convert the data into a bit stream form, which is the communication frame, and then modulate the communication frame to obtain a modulated signal, and finally send the modulated signal to the electronic device 200.

[0107] In the embodiments of the present application, the electronic device 100 and the electronic device 200 may include, but are not limited to, devices with wireless communication functions such as mobile phones, tablet computers, smart watches, etc. The embodiments of the present application do not limit the specific form and type of the electronic device 100 and the electronic device 200.

[0108] For reference Figure 2 , Figure 2 Exemplarily shows a process of the electronic device 100 generating a modulated signal.

[0109] As Figure 2 shown, 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 a modem to obtain the above-mentioned modulated signal. Among them, the communication information is the information that the electronic device 100 specifically wants to send, and this information may include text, pictures, videos, or instructions, etc. The electronic device 100 converts these communication information into a communication frame that the electronic device can recognize. The communication frame is the basic unit for transmitting data in a communication system and is a data packet composed of a series of bits with a specific format and structure.

[0110] 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 format of the communication frame generated by the electronic device 100 may be different.

[0111] During the process of 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 the gauss 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 sent.

[0112] It should be understood that GFSK (Gauss Frequency Shift Keying) is a modulation technique commonly used in wireless communication. In GFSK modulation, digital data is converted into a signal with frequency offset, and the electronic device represents different digital values by changing the offset of the carrier frequency. For example, the digital signal includes four level levels, corresponding to 00, 01, 10, and 11 respectively. Then, during the GFSK modulation process, the frequency of the carrier will be increased or decreased to obtain four different frequencies, corresponding one-to-one with the digital signal. In addition, before modulation, the electronic device will also process the digital signal using a Gaussian low-pass filter.

[0113] The communication frame format and the modulation technique are not necessarily coupled, that is to say, the frame format does not necessarily depend on the modulation technique. The frame format usually refers to the structure and organization method of the data frame, including the frame header, frame tail, data field, check code, etc. The modulation technique refers to the way of converting digital data into an analog signal.

[0114] However, in some communication standards or communication protocols, it is usually required that a specific modulation technique and frame format be used together to emphasize the combination of the modulation technique and frame format used in a specific scenario. Therefore, sometimes in order to more clearly describe a specific communication system or protocol, people will associate and name the frame format and the modulation technique. For example, the GFSK modulation technique is commonly used in Bluetooth communication. Therefore, the BLE or BLR frame format used in Bluetooth communication may be called the GFSK frame format to emphasize that this frame format is used under GFSK modulation.

[0115] The following combines Figure 3A - Figure 3C to introduce several common GFSK frame formats.

[0116] Figure 3A An exemplary communication frame format is shown. This communication frame can be the frame format used when an electronic device communicates through Bluetooth Low Energy (BLE) technology, hereinafter simply referred to as the BLE frame format.

[0117] As Figure 3A shown, the BLE frame format can include: a preamble sequence, an access address, a payload, a check field, and an extension field.

[0118] Among them, 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 the communication frame, and send it to the receiver together. The receiver can perform clock synchronization according to the alternating bit pattern of the preamble sequence in the communication frame, so that when the receiver starts to receive data, it can correctly parse the timing of the data. The alternating bit pattern of the preamble sequence can also be used for the receiver to perform frequency synchronization. The receiver can adjust its own receiving frequency by detecting the frequency characteristics of the preamble sequence to correctly receive subsequent data. The alternating bit pattern of the preamble sequence can also be used for the receiver to perform symbol time evaluation. The receiver can estimate the duration of each bit by observing the bit interval of the preamble sequence, so as to perform correct timing parsing in the subsequent data reception. The receiver can also configure the automatic gain control through the radio signal strength of the preamble sequence to adapt to data transmission with different signal strengths.

[0119] The access address can be used to distinguish different BLE communication connections. Each BLE communication connection will be 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 clocks and frequencies between communication devices. Before the start of communication, the sender and receiver will perform clock synchronization and frequency synchronization by exchanging the access address to ensure the correct transmission and reception of data. The access address also includes specific bit positions, and this specific bit position is used to indicate the type of the BLE frame. According to the bit positions in the access address, the receiver can determine whether the received communication frame is a broadcast frame, a data frame, or a control frame, and thus perform corresponding processing and parsing.

[0120] It should be understood that the access address can be a 32-bit field, conforming to the BLE protocol specification. Each BLE communication connection will use a different access address to ensure the uniqueness and distinguishability of the connection.

[0121] The payload refers to the actual data part carried in the frame.

[0122] The check field can be a check value calculated by the electronic device 100 for the payload, and is used to detect whether errors or damages occur during the transmission of the communication frame. Generally, in the BLE frame structure, cyclic redundancy check (CRC) is usually used as the check field. The CRC is usually a 24-bit check code. The sender calculates the data to generate a CRC check code 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 indicates that an error or damage may have occurred during the transmission of the frame.

[0123] The extended field is usually a constant tone extension (CTE) field, which is part of the function to support BLE direction finding. 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 sequence of constant modulation for the processing of the direction finding function. The length of the CTE field is usually between 16 μs and 160 μs.

[0124] Figure 3B Another communication frame format is exemplarily shown. This communication frame can be the frame format used when the electronic device communicates through the bluetooth long range (BLR) technology, hereinafter simply referred to as the BLR frame format.

[0125] The BLR frame format can include: a preamble sequence, an access address, a rate indicator field, an end symbol 1, a protocol data unit, and an end symbol 2. The functions of the preamble sequence and the access address are basically the same as those in the BLE frame structure, and the descriptions in the foregoing content can be referred to and will not be elaborated here.

[0126] In addition, compared with the BLE frame format, the BLR frame format also has additional fields such as a rate indicator field, an end symbol 1, an end symbol 2, and a protocol data unit. Among them, the rate indicator (RI) field is used to indicate the coding scheme adopted by the forward error correction coding block 2 (FEC Block2) in the following content.

[0127] The terminator 1 (term1) and the terminator 2 (term2) are terminators for the Coded PHY, used to identify the end of the Forward Error Correction Block 1 (FEC Block1) and the Forward Error Correction Block 2. In Coded PHY, to improve the reliability of transmission, Forward Error Correction (FEC) technology is used. FEC Block1 and FEC Block2 are the processes of dividing data into two blocks for encoding. Term1 can be the terminator of FEC Block1, term2 can be the terminator of FEC Block2, and each of term1 and term2 can consist of 3 bits. The receiver can identify the boundaries of FEC Block1 and FEC Block2 respectively based on the term1 and term2 for decoding and error correction.

[0128] The protocol data unit (PDU) can include a frame header, a payload, and a check field. The payload and the check field can refer to the descriptions in the foregoing content and will not be elaborated here. The frame header can include some control information of the frame, such as: the start identifier of the frame, the length of the frame, address information, etc. The receiver can correctly parse and process the received communication frame through the frame header.

[0129] Figure 3C Another communication frame format is exemplarily shown. As Figure 3C shown, this communication frame can be the wireless frame format 1 in the sparklink low energy (SLE) technology mode. The SLE wireless frame format 1 can include a preamble, an access address, a frame header, a header error control, a payload, and a check field. The descriptions of the preamble, the access address, the frame header, the payload, and the check field can refer to the above content and will not be elaborated here. Compared with the above two frame formats, the SLE wireless frame format 1 can also include a header error control (HEC). HEC is a technology used to detect and correct errors in the communication frame header, usually used to ensure the reliable transmission and correct parsing of the frame header.

[0130] Since the electronic device 100 usually also uses the GFSK modulation technology to modulate the communication frame when generating the communication frame in the above three communication frame formats. Therefore, the above three communication frame formats can also be called 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 method is mainly to accurately describe a specific communication system or protocol.

[0131] An electronic device can process communication frames using GFSK modulation technology with low power consumption based on a simple hardware design. However, all of the above three GFSK frame formats have certain limitations. For example, the length of the preamble sequence in the BLE frame format can be 8 microseconds, the length of the preamble sequence in the SLE wireless frame format 1 can be 10 microseconds, and the length of the preamble sequence in the BLR frame format can be 80 microseconds. Since the preamble sequences in the BLE frame format and the SLE wireless frame format 1 are shorter, the synchronization time before communication between the transceiver and the receiver is shorter. Therefore, the sensitivity of the BLE frame format and the SLE wireless frame format 1 is worse than that of the BLR frame format. Also, the transmission rate of the BLE frame format and the SLE wireless frame format 1 is determined by the bandwidth, and there are fewer transmission rate options.

[0132] Among them, sensitivity refers to the ability of the receiver to receive and parse a specific frame format during communication. A frame structure with better sensitivity means that the receiver can accurately receive and parse communication frames with this frame structure under lower signal strength or worse channel conditions. Generally, the sensitivity of a communication system is defined as the lowest signal strength at which the receiver in the system can correctly receive and parse communication frames.

[0133] One of the costs of the higher sensitivity of the BLR frame structure is that the overhead of the preamble sequence in the BLR frame structure is larger than that in the BLE frame structure and the SLE wireless frame structure 1. In addition, the coding method used for the payload and check field parts in the BLR frame structure is convolutional code, and only coding rates of one-half or one-eighth can be used. The transmission rate of a communication frame = bandwidth * coding rate. Therefore, when the bandwidth is determined, there are also fewer options for the transmission rate of the BLR frame structure. Generally, the bandwidth of the BLR frame structure is 1MHZ, and there are only two transmission rate options for the BLR frame structure, which are 500kbps and 125kbps.

[0134] To solve the problems existing in the GFSK frame format in the above content, the embodiments of the present application provide a data processing method. Using this method, an electronic device can generate a GFSK frame format with higher performance. In this method, after the electronic device generates a communication frame of the original information, frame processing is also performed on the communication frame. The frame processing can include one or more of polar coding the communication frame, spreading the communication frame, and inserting a pilot into the communication frame. After that, the processed communication frame is modulated using GFSK technology. In this way, the frame structure of the communication frame to be modulated can be improved, the receiving sensitivity and anti-interference performance of the communication system where the electronic device is located can be enhanced, and more transmission rate options can be provided. For reference Figure 4 , Figure 4 Exemplarily shows the process of another electronic device 100 provided by the embodiments of the present application for generating a modulation signal.

[0135] like Figure 4 As shown, 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.

[0136] The following is a detailed description of the data processing method process with reference to the accompanying drawings. Figure 5 , Figure 5 A flow chart of the data processing method is exemplarily shown.

[0137] like Figure 5 As shown, the data processing method may include the following steps S501 to S504.

[0138] S501. The electronic device 100 generates a communication frame 1.

[0139] 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.

[0140] For example, the format of the communication frame 1 may be as follows: Figure 6 As shown, the 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 can be referred to in the description above. The present embodiment does not limit the specific content of each field.

[0141] Optionally, the frame format of the communication frame 1 may also be the SLE wireless frame format 1 in the above content.

[0142] 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.

[0143] 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.

[0144] The core idea of polar coding lies in channel polarization, that is, using coding methods on the encoding side to make each sub-channel exhibit different reliabilities. When the code length continues to increase, some channels will tend to be noiseless channels with a capacity close to 1, and some channels will tend to be fully noisy channels with a capacity close to 0. Then, information is directly transmitted on the channels with a capacity close to 1 to approach the ideal channel capacity. Polar coding is the first coding method that has been theoretically proven to achieve the Shannon capacity. It has characteristics such as high performance and relatively low encoding and decoding complexity. At different code lengths, especially for finite codes, the performance of Polar codes is far better than that of parallel concatenated convolutional Turbo codes and low-density parity-check (LDPC) codes.

[0145] Polar coding can be implemented through a generator matrix, and reference can be made to Figure 7A , Figure 7A which exemplarily shows a schematic diagram of a polar coding generator matrix.

[0146] The codeword output by the electronic device 100 through polar coding is generally obtained by the product of the input vector and the generator matrix. The polar coding process of the electronic device 100 is x = uG, where x is a binary row vector with a length of L (i.e., the code length). G is an L-order matrix, that is, the polar coding generator matrix in the above content. u is the polar codeword generated by polar coding, and its length is also L. It should be noted that during the polar coding process, the generated polar code length is usually an integer power of 2. As Figure 7A shown, the polar code can be formed by the Kronecker product matrix based on G2.

[0147] If the electronic device 100 wants to generate a polar code with a length of L = 2 m words, the generator matrix to be used is the m-th power Kronecker product of G2. In Figure 7A , m is taken as 3 as an example. It can be used to generate a codeword with a length of 2 3 = 8.

[0148] The electronic device 100 can complete polar coding on the bit sequence through a polar encoder. Reference can be made to Figure 7B , Figure 7B which exemplarily shows a schematic diagram of a polar encoder based on a polar coding generator matrix.

[0149] As Figure 7B shown, taking 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 generator matrix is an 8-order matrix. The specific form of this generator matrix can be referred to Figure 7AThe matrix shown in []. Among them, the input vector may include information bits and frozen bits. During the process of polar coding, the electronic device 100 may calculate the channel capacity corresponding to 1 to L bits of the input vector according to the generating matrix G, and select the k positions with the largest channel capacity to transmit k information bits. The information bits may be the bits in the communication frame to be polar-coded. The other L-k positions with smaller channel capacity are frozen bits, and the frozen bits are fixed values (such as 0) pre-agreed by the transceiver. For example, when L = 8, the input vector may be u = [0, 0, 0, u3, 0, u5, u6, u7]. Among them, the positions of u3, u5, u6, and u7 have information bits. Correspondingly, the positions of u0, u1, u2, and u4 have frozen bits, and all the frozen bits are set to 0.

[0150] The specific implementation manner in which the electronic device 100 implements polar coding through a polar encoder may refer to Figure 7C , Figure 7C which exemplarily shows the implementation manner of the polar encoder.

[0151] As Figure 7C shown, still taking the input vector u when L = 8 in the above content as an example, all the frozen bits may be set to 0, and the circled "+" symbol represents 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 L-k (L-k = 4) frozen bits. The electronic device 100 obtains L coded bits through the operation shown in Figure 7C . This form of coding can be called polar coding. Figure 7C In [], all the frozen bits are set to 0. The frozen bits can also be set to other bit values known to both the sender and the receiver.

[0152] In a possible implementation manner, the electronic device 100 may perform polar 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 polar coding on the payload and the check field respectively. For example, if the payload is 1010 and the check field is 11, the electronic device 100 may perform polar coding on the bit sequences "1010" and "11" respectively. The electronic device 100 may also perform polar coding on the payload and the check field as a whole. For example, the electronic device 100 may directly perform polar coding on the bit sequence "101011". The descriptions of the payload and the check field here and in the following content are only symbolic examples for illustrating the concept of performing polar coding separately. In actual applications, the payload and the polar coding may also be other bit sequences, the relationship between the payload and the check field may also be other forms, and the check field may also be included in the payload. The present application does not limit the forms of the payload and the check field.

[0153] After polar encoding the payload and check field in communication frame 1, the electronic device 100 can also use direct sequence spread spectrum technology to perform spread spectrum processing on the payload and check field of communication frame 1. Through spread spectrum processing, the signal-to-noise ratio of the communication system can be improved, and the influence of noise or interference on the signal can be reduced during the communication process.

[0154] Figure 8 A comparison diagram of direct sequence spread spectrum is shown.

[0155] Direct sequence spread spectrum technology is a method for generating spread spectrum signals. By performing spread spectrum processing on signals, the signal bandwidth can be expanded, enabling the signal to be more widely distributed in the frequency domain, thereby improving the anti-interference ability of the communication system.

[0156] In the embodiments of this application, the electronic device 100 can use this direct sequence spread spectrum technology to perform spread spectrum processing on communication frames. The electronic device 100 can expand 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 can expand the bit 0 before spread spectrum into 00, and expand the bit 1 before spread spectrum into 11. If the bit sequence to be spread is 1011, the result after spread spectrum is 11001111.

[0157] Alternatively, the electronic device 100 can also use direct sequence spread spectrum technology to expand every A information bits in the object to be spread into B symbols, where both A and B are non-negative integers, and A is less than B.

[0158] As Figure 8 shown, when A = 4 and B = 16, the results before and after spread spectrum can be referred to Figure 8When 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 1111100010010100. 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 0000011010110111. 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. When the bit sequence is 0111, the spreading result can be 1011011100000110. When the bit sequence is 1111, the spreading result can be 1010110111000001.

[0159] In a possible implementation, the electronic device 100 can perform spreading processing on the payload and the check field respectively, or can perform spreading processing on the payload and the check field as a whole. For example, if the payload is 1010 and the check field is 11, the electronic device 100 can perform spreading processing on the bit sequences "1010" and "11" respectively. The electronic device 100 can also perform spreading processing on the payload and the check field as a whole. For example, the electronic device 100 can directly perform spreading processing on the bit sequence "101011". The embodiments of the present application do not limit this.

[0160] The electronic device 100 can also insert pilots into the payload and the check field in the spread communication frame 1.

[0161] A pilot is a type of auxiliary information used to assist the receiving end in identifying signals. Pilots can be used to help the receiving end locate the position and direction of signals, thereby more accurately identifying signals. Pilots are usually embedded in the data and appear at regular intervals or patterns to assist the receiving end in signal recovery and demodulation. Generally, before receiving the signal, the receiving party already knows the relevant information of the pilots inserted in the data. The receiving party can use the pilots to perform precise phase and carrier frequency offset tracking on the received signal.

[0162] Figure 9 A schematic diagram showing the insertion of pilots into a communication frame is presented.

[0163] As Figure 9 shown, the electronic device 100 can insert Y pilots every X symbols in the object where pilots are inserted. The inserted pilots are sequences known to both the transmitting and receiving ends, which can be set by the transmitting end and can include different sequences. For example, in the above communication system 300, when X = 8 and Y = 3, the electronic device 100 can set the pilots to alternate between 000 and 111. If the bit sequence before inserting the pilots is 01010010100001110100, the sequence after inserting the pilots can be 01010010000100001111110100.

[0164] In a possible implementation, the electronic device 100 can insert pilots into the payload and checksum fields respectively, or can also insert pilots with the payload and checksum fields as a whole. For example, the payload is 11110000 and the checksum field is 1111. The electronic device 100 can insert pilots into the sequences "11110000" and "1111" respectively, or can insert pilots into the sequence "111100001111". The embodiments of this application do not make any limitations in this regard.

[0165] In another possible implementation, the electronic device 100 can perform polarization coding on the frame header, payload, and checksum fields in the communication frame 1. In this case, the communication frame 1 includes a frame header, a payload, and a checksum field.

[0166] Similarly, the electronic device 100 can also perform spreading processing and insert pilots on the polarization-coded communication frame 1 successively, and the objects of the operations can be the frame header, payload, and checksum fields in the communication frame 1.

[0167] In a possible implementation, the electronic device 100 can perform the above polarization coding, spreading processing, and pilot insertion on the frame header, payload, and checksum fields respectively, or can also perform polarization coding, spreading processing, and pilot insertion on the frame header, payload, and checksum fields as a whole. The embodiments of this application do not make any limitations in this regard.

[0168] That is, the electronic device 100 can perform polarization coding on some fields in the communication frame 1. After polarization coding, the electronic device 100 can also perform spreading processing on these fields. After spreading processing, the electronic device 100 can also perform pilot insertion processing on these fields. These fields can be the payload and check fields in the communication frame 1, or can be the frame header, payload, and check fields in the communication frame 1. The prerequisite for these fields to be the payload and check fields is that the communication frame 1 includes the payload and check fields, and the prerequisite 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.

[0169] S503. The electronic device 100 performs Gaussian frequency shift keying (GFSK) modulation on the communication frame 2 to obtain a modulated signal 1.

[0170] S504. The electronic device 100 sends the modulated signal 1 to the electronic device 200.

[0171] After the electronic device 100 obtains the communication frame 2 through steps S501 and S502, the communication frame 2 has a GFSK frame format with higher performance. By modulating the communication frame 2 into the modulated signal 1 through GFSK modulation technology, the electronic device 100 can transmit information to the electronic device 200.

[0172] Figure 10 Another schematic flow diagram of the data processing method is exemplarily shown.

[0173] As Figure 10 shown, the data processing method may further include the following steps S1001 - step S1004.

[0174] S1001. The electronic device 100 generates a communication frame 3.

[0175] 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.

[0176] Exemplarily, the frame format of the communication frame 3 may be the same as the frame format of the above communication frame 1, or may be the same as the SLE wireless frame format 1 in the above content. The embodiments of the present application do not limit the specific content of each field in the communication frame 3.

[0177] S1002. The electronic device 100 performs pilot insertion processing on the payload and check fields in the communication frame 3 to obtain a communication frame 4.

[0178] In one possible implementation, the electronic device 100 may insert a pilot into the payload and check fields in the communication frame 3.

[0179] Before inserting the pilot, the electronic device 100 may also first perform polar coding on the payload and check field in the communication frame 3.
