[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] As mentioned in the background technology, how to find the WiFi signal for wireless access devices and electronic devices to communicate from numerous WiFi signals is an urgent problem to be solved. In the related technology, the electronic device can detect the strength of the surrounding WiFi signals and detect the WiFi signals in combination with the correlation calculation. Specifically, the electronic device detects the strength of the surrounding WiFi signals, and when the detected WiFi signal strength is greater than a certain threshold, the next step is performed. This process is to detect the degree of environmental interference of the current WiFi channel. If the WiFi signal strength is detected to be small, it indicates that the current environmental interference is large, then it is necessary to change the wireless access device. On the contrary, if the WiFi signal strength is detected to be large, then it is determined whether the detected WiFi is the desired signal, by determining the correlation between the detected WiFi signal and the preset WiFi signal, such as the correlation of the amplitude or phase of the WiFi signal. If the correlation is high, the corresponding demodulation is performed. If the correlation is low, it means that it is not the desired WiFi signal and is discarded.

[0040] The disadvantages of the above-mentioned related technologies are that when there are other WiFi signals around, on the one hand, there is interference from the noise environment, which affects the signal strength of the WiFi and has poor anti-interference ability. In addition, there are certain limitations in finding the desired WiFi signal from a large number of WiFi signals. If the WiFi connection between the wireless access device and the electronic device adopts the time division duplex (TDD) mode, the efficiency of the wireless transmission is not as high as the frequency division duplex (FDD) mode. If it is the FDD mode, it is necessary to distinguish different WiFi signals. If different devices transmit WiFi signals of the same frequency, it is difficult for the WiFi signal to detect the desired signal, and it is only suitable for WiFi signals of different frequencies. Figure 1Taking the 2.4G WiFi channel shown as an example, when the wireless access device and user 1 and user 2 are connected in FDD mode, when the WiFi channel is relatively idle, user 1 and user 2 can use different WiFi sub-channels for connection, such as user 1 using 2.4G channel 2 and user 2 using 2.4G channel 8. However, when the WiFi channel is very crowded and there are many WiFi interference signals around, especially when different users use the same WiFi sub-channel, such as user 1 and user 2 both use 2.4G channel 6, it is difficult to distinguish the desired WiFi signal from the WiFi signal interfering with the surrounding environment. On the other hand, it is necessary to determine the correlation between the received WiFi signal and the preset WiFi signal. Generally, the cross-correlation operation between the two is performed to obtain the cross-correlation coefficient. If the length of the received WiFi signal is too long, the amount of calculation is large, the more operation logic units are required, and the power consumption of the electronic device is large.

[0041] Based on the above, the present application provides a WiFi communication method, system, device, electronic device, wireless access device, computer storage medium and computer program product, which can effectively find the desired signal among the numerous surrounding WiFi signals, have strong anti-interference ability, do not need to perform complex related calculations, reduce the amount of calculations, and improve WiFi throughput and transmission quality.

[0042] The WiFi communication method provided in the embodiment of the present application can be applied to Figure 2 In the application environment shown. Among them, the electronic device 102 communicates with the wireless access device 104 through a WiFi network. The electronic device 102 and the wireless access device 104 can store corresponding orthogonal codec programs. Among them, the electronic device 102 can be but not limited to various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The wireless access device 104 can be a wireless access point (AP) device, a wireless router, a wireless connector, etc. In this application, there is no limitation on the electronic device 102 and the wireless access device 104.

[0043] In one embodiment, Figure 3 As shown, a WiFi communication method is provided, and the method is applied to Figure 1 The electronic device in is used as an example for explanation. Among them, the electronic device is pre-configured with a target orthogonal code, and the target orthogonal code is used to perform WiFi communication with the wireless access device. The WiFi communication method provided in this application may include the following steps S302 to S306.

[0044] S302: Receive multiple coded signals sent by a wireless access device.

[0045] The wireless access device pre-stores a plurality of mutually orthogonal orthogonal codes, and the target orthogonal code is one of the plurality of orthogonal codes. The wireless access device pre-stores a target orthogonal code and a first orthogonal code, wherein the target orthogonal code is 10, the first orthogonal code is 01, and the target orthogonal code is orthogonal to the first orthogonal code. Exemplarily, the plurality of orthogonal codes may be different column vectors or different row vectors of a Walsh matrix. In the present application, no limitation is imposed on the plurality of orthogonal codes pre-stored by the wireless access device.

[0046] The coded signal sent by the wireless access device is a signal generated by the wireless access device encoding the initial WiFi signal using an orthogonal code, and each coded signal uses a different orthogonal code. The multiple coded signals sent by the wireless access device include a target coded signal generated by the wireless access device encoding the initial WiFi signal using a target orthogonal code.

[0047] S304: Decode each coded signal according to the target orthogonal code to obtain a plurality of corresponding decoded signals. The electronic device decodes the coded signal using a decoding method corresponding to the coding method of the wireless access device to obtain a decoded signal corresponding to each coded signal.

[0048] S306: Determine a target WiFi signal according to each decoded signal, wherein the target WiFi signal is a communication signal between the electronic device and the wireless access device, and the target WiFi signal is a signal obtained by the electronic device after decoding using the target orthogonal code.

[0049] In the above-mentioned WiFi communication method, during the WiFi communication process between the electronic device and the wireless access device, since the wireless access device will encode the initial WiFi signal using multiple mutually orthogonal codes stored in advance before transmitting it to the electronic device, after the electronic device receives the multiple coded signals sent by the wireless access device, it can use the target orthogonal code to decode the multiple coded signals to obtain multiple decoded signals accordingly. Since the target orthogonal code is orthogonal to other orthogonal codes pre-stored by the wireless access device, the electronic device can determine the target WiFi signal that communicates with the wireless access device from the multiple decoded signals, thereby achieving effective search for the target WiFi signal, improving anti-interference performance, and not requiring complex correlation operations, reducing the amount of calculation. The method is not only applicable to WiFi communication in TDD mode, but also to WiFi communication in FDD mode, thereby improving the throughput of WiFi communication and the quality of signal transmission, and can bring a better user experience.

[0050] In one embodiment, Figure 4As shown, step S304: decoding each coded signal according to the target orthogonal code respectively, and correspondingly obtaining multiple decoded signals, may include the following steps S402 and S404.

[0051] S402: Obtain inner product values ​​of the target orthogonal code and each coded signal respectively.

[0052] S404: Obtain decoded signals corresponding to the encoded signals according to the inner product values.

[0053] Since the target orthogonal code is orthogonal to other orthogonal codes pre-stored in the wireless access device, according to the orthogonal characteristics of the orthogonal code, the inner product value of the target orthogonal code and the target coded signal is not 0, so the target WiFi signal is a decoded signal whose inner product value is not 0; the inner product value of the target orthogonal code and other coded signals is 0, and the coded signal corresponding to the inner product value of 0 is an interference signal. Among them, the target coded signal refers to the signal generated by the wireless access device after encoding the initial WiFi signal using the target orthogonal code. Based on this, the electronic device can effectively find the target WiFi signal that communicates with the wireless access device from multiple coded signals according to the inner product value corresponding to each coded signal, thereby improving the anti-interference performance, avoiding a large amount of calculations caused by related calculations, and improving the throughput and signal transmission quality of WiFi communication.

[0054] In one embodiment, the initial WiFi signal includes a binary sequence signal, in other words, the initial WiFi signal is a binary 01 sequence. For example, the initial WiFi signal is 1100. Based on this, step S302: obtaining the decoded signal corresponding to each coded signal according to each inner product value, may include: obtaining the decoded signal corresponding to each coded signal according to each inner product value and a preset first decoding method. Among them, the first decoding method is: determining an inner product value greater than 0 as a binary number 0 and determining an inner product value less than 0 as a binary number 1. In other words, if the inner product value is greater than 0, it indicates that the initial WiFi signal sent by the wireless access device is a binary number 0; if the inner product value is less than 0, it indicates that the initial WiFi signal sent by the wireless access device is a binary number 1.

[0055] Accordingly, the wireless access device is used to encode the initial WiFi signal according to the orthogonal code and the preset first encoding method, and generate multiple encoded signals accordingly. Among them, the target encoded signal included in the multiple encoded signals is generated by the wireless access device encoding the initial WiFi signal using the target orthogonal code and the first encoding method. Among them, the first encoding method is: encoding the binary number 0 in the initial WiFi signal as an orthogonal code, and encoding the binary number 1 in the initial WiFi signal as the inverse code of the orthogonal code.

[0056] For example, the initial WiFi signal includes a binary number 1, and the wireless access device pre-stores a target orthogonal code 10 and a first orthogonal code 01. The target coded signal generated after encoding the initial WiFi signal 1 using the target orthogonal code 10 and the first coding method is 01, and the first coded signal generated after encoding the initial WiFi signal 1 using the first orthogonal code 01 and the first coding method is 10.

[0057] In the above WiFi communication method, the electronic device decodes the coded signal using the first decoding method corresponding to the first coding method, so that the target WiFi signal can be correctly decoded from each coded signal and found, thereby improving the anti-interference performance of WiFi communication and reducing the related calculation amount.

[0058] In one embodiment, the initial WiFi signal includes a binary sequence signal. Based on this, step S302: obtaining the decoded signal corresponding to each coded signal according to each inner product value, may include: obtaining the decoded signal corresponding to each coded signal according to each inner product value and a preset second decoding method. Among them, the second decoding method is: determining an inner product value greater than 0 as a binary number 1 and determining an inner product value less than 0 as a binary number 0. In other words, if the inner product value is greater than 0, it indicates that the initial WiFi signal sent by the wireless access device is a binary number 1; if the inner product value is less than 0, it indicates that the initial WiFi signal sent by the wireless access device is a binary number 0.

[0059] Accordingly, the wireless access device is used to encode the initial WiFi signal according to the orthogonal code and the preset second encoding method, and generate multiple encoded signals accordingly. Among them, the target encoded signal included in the multiple encoded signals is generated by the wireless access device encoding the initial WiFi signal using the target orthogonal code and the second encoding method. Among them, the second encoding method is: encoding the binary number 1 in the initial WiFi signal as an orthogonal code, and encoding the binary number 0 in the initial WiFi signal as the inverse code of the orthogonal code.

[0060] For example, the initial WiFi signal includes a binary number 1, and the wireless access device pre-stores a target orthogonal code 10 and a first orthogonal code 01. The target coded signal generated by encoding the initial WiFi signal 1 using the target orthogonal code 10 and the second coding method is 10, and the first coded signal generated by encoding the initial WiFi signal 1 using the first orthogonal code 01 and the first coding method is 01.

[0061] In the above WiFi communication method, the electronic device decodes the coded signal using the second decoding method corresponding to the second coding method, so that the target WiFi signal can be correctly decoded from each coded signal and found, thereby improving the anti-interference performance of WiFi communication and reducing the related calculation amount.

[0062] In one embodiment, the WiFi communication method may further include: determining the connection status with the wireless access device according to the inner product value corresponding to the target WiFi signal. Since there is a certain distance between the electronic device and the wireless access device, and there is loss during signal transmission, the coded signal received by the electronic device will have a certain signal attenuation compared to the coded signal sent by the wireless access device. For example, the coded signal sent by the wireless access device is a binary number 1, and the coded signal received by the electronic device may be 0.6 or 0.8. Based on this, the electronic device can screen the wireless access device according to the inner product value calculated during the decoding process to ensure a high WiFi communication quality.

[0063] In one embodiment, Figure 5 As shown, the above step, i.e. the electronic device determines the connection status with the wireless access device according to the inner product value corresponding to the target WiFi signal, may include the following steps S502 and S504.

[0064] S502: When the absolute value of the inner product value corresponding to the target WiFi signal is less than a preset connection threshold, disconnect the wireless access device.

[0065] The preset connection threshold is pre-set and can be determined according to an experimental value, and is not limited here. If the absolute value of the inner product value corresponding to the target WiFi signal is less than the preset connection threshold, it indicates that the quality of the target WiFi signal is poor, and the quality of the WiFi signal for communication between the electronic device and the wireless access device is poor. In this case, the electronic device can disconnect from the wireless access device.

[0066] Furthermore, in an application scenario where there are multiple wireless access devices, there are differences in the distance between the electronic device and each wireless access device, so there are differences in the strength of the signal received by the electronic device, and thus, there are differences in the inner product value corresponding to the target coded signal determined by the electronic device decoding. Taking the wireless access device including the first wireless access device and the second wireless access device as an example, if the electronic device is first connected to the first wireless access device, and it is determined that the absolute value of the inner product value corresponding to the first target coded signal is less than the preset connection threshold, the connection with the first wireless access device is disconnected, and the second wireless access device is connected to find a better quality WiFi signal, thereby realizing the switching of the wireless access device and improving the transmission quality of the WiFi signal.

[0067] like Figure 6As shown, another application scenario of the WiFi communication method is provided. In this application scenario, the electronic devices include a smartphone 102a of user 1 and a smartphone 102b of user 2, and the wireless access devices include a wireless access point 104a and a wireless access point 104b. During the WiFi communication process, the best access point for user 1 is the wireless access point 104a, and the best access point for user 2 is the wireless access point 104b.

[0068] S504: When the absolute value of the inner product value corresponding to the target WiFi signal is greater than or equal to a preset connection threshold, maintain connection with the wireless access device.

[0069] If the absolute value of the inner product value corresponding to the target WiFi signal is less than the preset connection threshold, it indicates that the quality of the target WiFi signal is good, and the quality of the WiFi signal for communication between the electronic device and the wireless access device is good. In this case, the electronic device can maintain connection with the wireless access device and maintain WiFi communication with the wireless access device.

[0070] With the above WiFi communication method, the electronic device can switch the wireless access device according to the inner product value corresponding to the target WiFi signal, thereby improving the WiFi communication quality between the electronic device and the wireless access device and further improving the user experience.

[0071] In one embodiment, Figure 6 As shown, there are multiple wireless access devices for WiFi communication with electronic devices. Based on this, Figure 7 As shown, the WiFi communication method may further include the following steps S702 to S706.

[0072] S702: Receive initial WiFi signals sent by multiple wireless access devices, wherein the initial WiFi signals are signals that are not encoded by the wireless access devices using orthogonal codes.

[0073] S704: Determine a target wireless access device from a plurality of wireless access devices according to the strength information of each initial WiFi signal.

[0074] Exemplarily, the electronic device may use the wireless access device corresponding to the maximum value of the strength information as the target access device to connect to the target wireless access device.

[0075] S706: Send a target orthogonal code to a target wireless access device.

[0076] Based on the above step S704, after the electronic device determines the target electronic device, it can send a pre-configured target orthogonal code to the target access device, so that during the process of WiFi communication between the target access device and the electronic device, the target orthogonal code can be used to perform orthogonal precoding on the initial WiFi signal to be transmitted, and then the electronic device uses the target orthogonal code to perform corresponding orthogonal decoding, thereby finding the desired target WiFi signal among the numerous WiFi signals.

[0077] In the above WiFi communication method, the electronic device determines the target wireless access device with better WiFi communication quality by comparing the strength information of the initial WiFi signals sent by each wireless access device, thereby realizing the preliminary screening before WiFi communication and further improving the transmission quality of the WiFi signal.

[0078] Based on the same inventive concept as above, the present application also provides another WiFi communication method, which is applied to Figure 2 The wireless access device shown in the figure is pre-configured with an orthogonal coding program to encode the initial WiFi signal to be transmitted using a plurality of pre-stored mutually orthogonal orthogonal codes to achieve WiFi communication with the electronic device. Figure 8 As shown, the WiFi communication method may include the following steps S802 and S804.

[0079] S802: Encode the initial WiFi signal using a plurality of mutually orthogonal orthogonal codes stored in advance, and generate a plurality of coded signals accordingly. The orthogonal codes used by the coded signals are different, and the target orthogonal code corresponding to the electronic device that performs WiFi communication with the wireless access device is one of the plurality of orthogonal codes. The plurality of coded signals include a target coded signal generated by numbering the initial WiFi signal using the target orthogonal code.

[0080] S804: Send each coded signal to instruct the electronic device to decode each coded signal using a pre-configured target orthogonal code, and determine a target WiFi signal according to a decoded signal corresponding to each coded signal.

[0081] The target WiFi signal is a communication signal between a wireless access device and an electronic device, and the target orthogonal code is one of a plurality of orthogonal codes. The target WiFi signal is a signal determined after the electronic device decodes the target coded signal using the target orthogonal code.

[0082] In the above-mentioned WiFi communication method, during the WiFi communication process between the wireless access device and the electronic device, the wireless access device will encode the initial WiFi signal using a plurality of mutually orthogonal codes pre-stored, generate a coded signal corresponding to each orthogonal code, and send each coded signal. Since the target orthogonal code is orthogonal to other orthogonal codes pre-stored by the wireless access device, after receiving the plurality of coded signals, the electronic device can use the target orthogonal code to decode the plurality of decoded signals and determine the target WiFi signal communicating with the wireless access device therefrom, thereby achieving effective search for the target WiFi signal, improving anti-interference performance, and eliminating the need for complex correlation operations, reducing the amount of calculation. The method is not only applicable to WiFi communication in TDD mode, but also to WiFi communication in FDD mode, thereby improving the throughput of WiFi communication and the quality of signal transmission, and can bring a better user experience.

[0083] In one embodiment, the initial WiFi signal includes a binary sequence signal. Based on this, step S702, using a plurality of pre-stored mutually orthogonal orthogonal codes to encode the initial WiFi signal, may include: using a plurality of pre-stored mutually orthogonal orthogonal codes and a preset first encoding method to encode the initial WiFi signal. Among them, the first encoding method is: encoding the binary number 0 in the initial WiFi signal as an orthogonal code, and encoding the binary number 1 in the initial WiFi signal as the inverse code of the orthogonal code. Among them, the electronic device is used to perform an inner product with each coded signal according to the target orthogonal code, and obtain the decoded signal corresponding to each coded signal according to each inner product value and a preset first decoding method. Among them, the target WiFi signal is a decoded signal with an inner product value of 0, and the first decoding method is: determining an inner product value greater than 0 as a binary number 0, and determining an inner product value less than 0 as a binary number 1. The encoding and decoding process can refer to the relevant content of the embodiment of the WiFi communication method applied to the electronic device above, and will not be repeated here.

The orthogonal codes used by each coded signal are different. The electronic device 102 is used to receive each coded signal and decode each of the coded signals according to a pre-configured target orthogonal code, correspondingly obtain a plurality of decoded signals, and determine the target WiFi signal according to each decoded signal. The target WiFi signal is a communication signal between the electronic device and the wireless access device, and the target orthogonal code is one of the plurality of orthogonal codes.

[0088] The above-mentioned WiFi communication system includes an electronic device and a wireless access device. During the WiFi communication process, the wireless access device uses a plurality of mutually orthogonal orthogonal codes pre-stored to encode the initial WiFi signal, and sends a plurality of coded signals corresponding to each orthogonal code. After the electronic device receives the plurality of coded signals sent by the wireless access device, it can use the target orthogonal code to decode the plurality of coded signals to obtain a plurality of decoded signals. Since the target orthogonal code is orthogonal to other orthogonal codes pre-stored by the wireless access device, the electronic device can determine the target WiFi signal communicating with the wireless access device from the plurality of decoded signals, thereby achieving effective search for the target WiFi signal, improving anti-interference performance, and not requiring complex correlation operations, reducing the amount of calculation. The method is not only applicable to WiFi communication in TDD mode, but also to WiFi communication in FDD mode, thereby improving the throughput of WiFi communication and the quality of signal transmission, and can bring a better user experience.

[0089] In one embodiment, a WiFi communication system includes at least two wireless access devices. Each wireless access device is further configured to send an initial WiFi signal, which is a signal not encoded using an orthogonal code. The terminal device is further configured to receive the initial WiFi signal sent by each wireless access device, and determine a target wireless access device from a plurality of wireless access devices based on the strength information of each initial WiFi signal, and send a target orthogonal code to the target wireless access device.

[0090] In one embodiment, the system comprises at least two electronic devices, each electronic device being pre-configured with mutually orthogonal codes.

[0091] In one embodiment, each orthogonal code is a different column vector or a different row vector in a Walsh matrix. The orthogonal code can be generated by Walsh transformation. The matrix generated by Walsh transformation has the advantage of fast operation, and each column vector or each row vector is mutually orthogonal. Therefore, in the embodiment of the present application, each orthogonal column vector or row vector in the Walsh matrix can be respectively corresponded to a different wireless access device or electronic device for corresponding demodulation.

[0092] For a better understanding, Figure 4 Taking the WiFi communication system shown in the figure as an example, each electronic device is pre-configured with mutually orthogonal orthogonal codes. When the electronic device searches for WiFi in the surrounding environment, it finds that the WiFi signal comes from different wireless access devices and surrounding electronic devices. Here, the WiFi connected by FDD is taken as an example. Fig. 9 As shown, in order to find a suitable WiFi signal, you can do the following:

[0093] S901: Each wireless electronic device sends an initial WiFi signal.

[0094] S902: The electronic device receives the initial WiFi signals sent by each wireless electronic device, and determines the wireless access device corresponding to the maximum value of the strength information of each initial WiFi signal as the target wireless access device.

[0095] S903: The electronic device sends a target orthogonal code to a target wireless access device.

[0096] S904: The target wireless access device stores the target orthogonal code.

[0097] S905: During the WiFi communication process, the target wireless access device encodes the initial WiFi signal according to a plurality of mutually orthogonal orthogonal codes pre-stored and a first encoding method, and generates a plurality of encoded signals accordingly. The plurality of orthogonal codes include a target orthogonal code, and the orthogonal codes used by the encoded signals are different. The initial WiFi signal is a binary sequence signal, and the first encoding method is: encoding the binary number 0 in the initial WiFi signal as the orthogonal code, and encoding the binary number 1 in the initial WiFi signal as the inverse code of the orthogonal code.

[0098] S906: The target wireless access device sends multiple coded signals.

[0099] S907: The electronic device receives multiple coded signals sent by the wireless access device, obtains the inner product values ​​of the target orthogonal code and the inner product of each coded signal, and determines the target WiFi signal communicating with the wireless access device according to each inner product value and the first decoding method. Among them, the first decoding method is: determining the inner product value greater than 0 as the binary number 0 and the inner product value less than 0 as the binary number 1. Among them, the coded signal corresponding to the inner product value of 0 is the interference signal. Based on this, the electronic device performs correct signal transmission with the wireless access device, avoids interference from surrounding WiFi signals, and does not perform unnecessary other WiFi signal calculations.

[0100] The above is the transmission process of wireless devices and electronic devices. According to the characteristics of orthogonal codes, when the wireless access device and the electronic device code are the same, the inner product result is not zero. When they are orthogonal to each other, the inner product is zero to identify different WiFi signals. When the wireless access device and user 1 and user 2 are connected in FDD mode, when the WiFi channel is relatively idle, user 1 and user 2 can use different WiFi sub-channels for connection; when the WiFi channel is very crowded and there are many WiFi interference signals around, especially when different users use the same WiFi sub-channel, such as user 1 and user 2 use the same WiFi sub-channel, this application can be used, that is, the orthogonal code is introduced in the connection method of the FDD mode WiFi, and the corresponding user 1 and user 2 signals can be demodulated according to the characteristics of the orthogonal code.

[0101] The above-mentioned WiFi connection method based on orthogonal code encoding and decoding has a certain anti-interference ability and has the function of automatically switching the best line. Due to the distance between the electronic device and the wireless access device, the strength of the received signal is different. In this way, the inner product value obtained during the decoding process is different. The wireless access device can be switched according to the size of the inner product value. For example, the best access point for user 1 is wireless access point 1, and the best access point for user 2 is wireless access point 2, thereby improving the transmission quality of WiFi.

[0102] The above-mentioned WiFi communication method based on orthogonal codes can effectively find the desired signal among numerous WiFi signals around, has the ability to resist interference, and has the function of automatically switching to the best wireless access device. It does not require complex related operations and reduces the amount of calculation. It can be realized by storing the corresponding orthogonal encoding and decoding program in the wireless access device and the electronic device, especially in the increasingly crowded WiFi channels, improving the WiFi throughput and transmission quality, and bringing a better user experience.
