[0055] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.
[0056] The digital signal decoding method provided in the present disclosure is applied to a scenario where an electronic device decodes a high-speed digital signal, for example, it is applied to a scenario where an electronic device decodes a high-speed digital signal under interference from a radio frequency signal.
[0057] With the development of science and technology, electronic devices are gradually integrated into people's daily lives. As people's requirements for the performance of electronic devices continue to increase, the amount of data that electronic devices need to transmit also increases. Between the various functional modules of the device, large amounts of data can be transmitted through high-speed signals. Figure 1 FIG. 1 is a schematic diagram of a process control block of an electronic device according to an exemplary embodiment. Figure 1As shown, the process control block (PCB) mainboard 8 of the electronic device may include a camera module 1, a central processing unit module 2, a memory module 3, a screen display module 4, a peripheral module 5, a radio frequency front-end module and a radio frequency modulator 6, a flexible printed circuit board 7 for connecting the modules, and other user peripheral modules 5, such as a digital sound format (Audio) peripheral module, a sensor (Sensor) peripheral module, and a subscriber identity module (Subscriber Identity Module, SIM) peripheral module. In the electronic device, each module is used to perform different functions, wherein the camera module is used to realize functions such as taking pictures and recording, and transmits the image data to the central processing unit (CPU) module 2 through the mobile industry processor interface (MIPI) signal line, and the CPU module 2 transmits the digital signal of the camera image to the screen display module 4, and transmits part of the image data to the memory module 3. In the use of the camera or the screen, the radio frequency front-end module and the radio frequency modulator 6 are often accompanied by the transmission of wireless signals through the nature of the electronic device. During the wireless signal transmission process, the high-power RF transmission signal will be coupled to the flexible printed circuit board (Flexible Printed Circuit, FPC) or the exposed high-speed interface connector or the module itself due to the limitations of the structural stacking of the electronic equipment, causing the RF transmission signal energy to be superimposed on the high-speed signal, thereby distorting the high-speed digital signal and making it unable to be decoded normally, resulting in the failure of the corresponding functions corresponding to the high-speed digital signal.
[0058] In the related art, the problem of radio frequency signal interference with digital signal decoding can only be mitigated by sacrificing the performance of some functional modules or increasing hardware costs. For example, when a module that needs to transmit data through a high-speed digital signal transmits data, the antenna transmission power is reduced or the transmission path of the radio frequency signal that interferes with the high-speed digital signal is completely closed. However, this method causes the data throughput of the electronic device to decrease and affects the antenna signal quality; or the distance between the antenna and the module that needs to transmit high-speed digital signals can be increased, but this method will cause the layout of the electronic device to be severely restricted, causing the electronic device to lose its stacking competitiveness; or conductive materials can be added to the key path for high-speed digital signal transmission, but this method can only reduce the degree of interference of high-speed digital signals; or a filtering circuit is added, but this method can only reduce the degree of interference of high-speed digital signals in a specific frequency band due to the hardware-specific delay and insertion loss imbalance; or the radio frequency interference signal is superimposed on the MIPI signal, but when the CPU module cannot distinguish between useful signals and useless signals, it cannot change the interference of high-speed digital signals with radio frequency signals when the high-speed digital signals coexist with radio frequency signals.
[0059] Therefore, the present invention adjusts the signal parameters used for digital signal decoding based on the power of the radio frequency signal emitted by the electronic device, thereby achieving normal decoding of the digital signal when the digital signal and the radio frequency signal coexist, improving the anti-interference ability of the digital signal and optimizing the performance.
[0060] Figure 2 is a flow chart of a digital signal decoding method according to an exemplary embodiment. Figure 2 As shown, the digital signal decoding method is used in an electronic device and includes the following steps.
[0061] In step S11 , in response to determining that the electronic device is about to decode a digital signal, a radio frequency signal transmitted by the electronic device is detected.
[0062] In the disclosed embodiment, when the electronic device detects that a digital signal is about to be decoded, the radio frequency signal sent by the electronic device is detected. For example, in the electronic device, the camera module can transmit high-speed digital signals. When the electronic device detects that the user clicks the camera icon in the electronic device, the radio frequency signal sent by the current electronic device is detected.
[0063] In the embodiment of the present disclosure, detecting the radio frequency signal may be detecting the frequency of the radio frequency signal, or may be detecting the power of the radio frequency signal.
[0064] In the embodiment of the present disclosure, the radio frequency signal may be a wireless signal transmitted through an antenna.
[0065] In the embodiment of the present disclosure, the type of digital signal to be decoded by the electronic device may be determined through the detected user operation.
[0066] In step S12, in response to detecting a radio frequency signal and the transmission power of the radio frequency signal being greater than a threshold, a signal parameter of the decoded digital signal is determined.
[0067] The threshold is a power threshold that interferes with the decoded digital signal.
[0068] In the disclosed embodiment, the power threshold of the interference to the decoded digital signal can be determined by relevant technicians according to actual test conditions, wherein the power threshold of the radio frequency signal that interferes with the digital signal can be different for different digital signals. For example, when the digital signal is a high-speed digital signal applied to a camera module, it is detected that when the transmission power of the radio frequency signal is 25 decibel milliwatts (dBm), the camera module displays an abnormality, then it can be determined that the power threshold of the radio frequency signal affected by the high-speed digital signal is 25dBm.
[0069] In the embodiment of the present disclosure, when it is detected that the power of the radio frequency signal transmitted by the electronic device is greater than a threshold, a signal parameter of a digital signal corresponding to the radio frequency signal with the current transmission power is determined for decoding.
[0070] In step S13, the digital signal is decoded based on the signal parameters.
[0071] In the embodiment of the present disclosure, based on the signal parameters used to decode the digital signal determined by the current radio frequency signal, normal decoding of the digital signal can be achieved.
[0072] In the disclosed embodiment, the signal parameters of the decoded digital signal are adjusted based on the radio frequency signal before decoding the digital signal, so that the digital signal can still be decoded normally under the interference of the radio frequency signal, thereby improving the anti-interference ability of the digital signal and optimizing the performance of the digital signal.
[0073] In the disclosed embodiment, the signal parameters of the decoded digital signal may be stored in a coexistence table of the radio frequency signal and the digital signal, wherein the coexistence table of the radio frequency signal and the digital signal may be pre-designed by relevant technical personnel according to actual conditions.
[0074] Figure 3 is a flow chart of a digital signal decoding method according to an exemplary embodiment. Figure 3 As shown, the digital signal decoding method is used in an electronic device and includes the following steps.
[0075] In step S21 , in response to determining that the electronic device is about to decode a digital signal, a radio frequency signal transmitted by the electronic device is detected.
[0076] In the embodiment of the present disclosure, step S21 and step S23 are consistent with step S11 and step S13, and will not be described in detail here.
[0077] In step S22, in response to detecting a radio frequency signal and the transmission power of the radio frequency signal being greater than a threshold, signal parameters corresponding to correctly decoding the digital signal under radio frequency signal interference are obtained based on a coexistence table matching the radio frequency signal and the digital signal.
[0078] The coexistence table is used to store the corresponding relationship between the radio frequency signal transmission parameters and the signal parameters of the digital signal.
[0079] The signal parameters satisfy the requirement that the digital signal can be correctly decoded when the radio frequency signal is transmitted using the transmission parameters.
[0080] In the embodiment of the present disclosure, the coexistence table may be stored in a memory in the electronic device, and the coexistence table may be used to store the correspondence between the transmission parameters of different radio frequency signals and the signal parameters of different digital signals.
[0081] In the disclosed embodiment, the central processor of the electronic device may determine the corresponding signal parameters capable of correctly decoding the digital signal under the interference of the RF signal of the current transmission parameters based on the coexistence table of the matching RF signal and the digital signal.
[0082] In step S23, the digital signal is decoded based on the signal parameters.
[0083] In the disclosed embodiment, Figure 4 FIG. 1 is a schematic diagram showing the interaction between a digital signal processing module and a radio frequency module according to an exemplary embodiment. Figure 4 As shown, when the electronic device detects the RF signal sent by the RF front-end module and the RF modulator 6 and determines that the transmission power of the RF signal is greater than the threshold corresponding to the current digital signal, the memory module 3 retrieves the coexistence table of the matching RF signal and the digital signal. Based on the coexistence table of the matching RF signal and the digital signal, the signal parameters of the correctly decoded digital signal corresponding to the current RF signal and the digital signal are determined. The signal parameters that can be decoded normally are sent to the central processing unit module 2. The central processing unit module 2 decodes the current digital signal based on the correct signal parameters.
[0084] In the disclosed embodiment, by calling the coexistence table of matching radio frequency signals and digital signals, the signal parameters corresponding to the current radio frequency signal and capable of correctly decoding the digital signal can be quickly found based on the coexistence table, thereby improving the efficiency of signal parameter acquisition. Furthermore, the digital signal is decoded based on the signal parameters capable of normally decoding the digital signal, thereby improving the anti-interference capability of the digital signal and optimizing the performance.
[0085] In the embodiments of the present disclosure, due to different services, the antenna of the electronic device may transmit different radio frequency signals corresponding to the services, and the transmission parameters corresponding to the different radio frequency signals may be different.
[0086] Figure 5 is a flowchart of a digital signal decoding method based on changes in transmission parameters of a radio frequency signal according to an exemplary embodiment, such as Figure 5 As shown, the digital signal decoding method is used in an electronic device and includes the following steps.
[0087] In step S31, in response to detecting that a transmission parameter of a radio frequency signal has changed, a signal parameter of a decoded digital signal is re-determined.
[0088] In an embodiment of the present disclosure, when the electronic device detects that the transmission parameters of the radio frequency signal transmitted by the antenna have changed, it calls a coexistence table that matches the radio frequency signal and the digital signal, and determines based on the changed radio frequency signal transmission parameters, obtains the signal parameters corresponding to the changed radio frequency signal in the coexistence table, wherein the signal parameters can be used to correctly decode the digital signal corresponding to the current radio frequency signal.
[0089] In step S32, the digital signal is decoded based on the re-determined signal parameters.
[0090] In the implementation of the present disclosure, when the electronic device determines that the transmission parameters of the radio frequency signal have changed, the memory in the electronic device can determine the signal parameters corresponding to the changed transmission parameters of the radio frequency signal based on the coexistence table, and send the signal parameters to the central processor. The central processor decodes the digital signal based on the signal parameters corresponding to the changed transmission parameters of the radio frequency signal. For example, Figure 4 As shown, when it is detected that the transmission parameters of the RF signal generated by the RF front-end module and the RF modulator 6 have changed, the memory module 3 determines the signal parameters corresponding to the correctly decoded digital signal corresponding to the changed RF signal transmission parameters based on the coexistence table pre-stored in the memory. And send the signal parameters to the central processing unit module 2, and the central processing unit module 2 can decode the digital signal based on the signal parameters. Thus, the digital signal is decoded normally.
[0091] In the disclosed embodiment, when a change in the transmission parameters of the radio frequency signal is detected, the signal parameters of the decoded digital signal corresponding to the changed radio frequency signal are re-determined, so that the digital signal can still be decoded normally under the interference of radio frequency signals in any frequency band, thereby improving the anti-interference ability of the digital signal and avoiding the situation where the anti-interference ability of the digital signal is limited to radio frequency signals in a specific frequency band.
[0092] In the implementation of the present disclosure, the coexistence table for matching the radio frequency signal and the digital signal can be pre-determined by relevant technicians based on the transmission parameters of different radio frequency signals and stored in the memory of the electronic device.
[0093] Figure 6 is a flowchart of a digital signal decoding method for determining a coexistence table according to an exemplary embodiment. Figure 6 As shown, the digital signal decoding method is used in an electronic device and includes the following steps.
[0094] In step S41, the electronic device is set to transmit a target radio frequency signal with target transmission parameters, and the electronic device is controlled to run a target application.
[0095] In the embodiments of the present disclosure, the transmission frequency of the radio frequency signal and / or the transmission power of the radio frequency signal may be set.
[0096] In the embodiments of the present disclosure, different target applications may correspond to different digital signals, and the power thresholds of the interfered radio frequency signals corresponding to different digital signals are different.
[0097] In the implementation of the present disclosure, relevant technicians can set the target transmission parameters of the electronic device to transmit the target radio frequency signal and control the electronic device to run the target application. It can be understood that controlling the electronic device to run the target application can be understood as transmitting the digital signal so that the target application of the electronic device receives the digital signal and decodes it, and realizes the function corresponding to the digital signal according to the decoding result.
[0098] In step S42, the target signal parameters correctly decoded by the digital signal used by the target application are scanned, and the target transmission parameters and the target signal parameters are stored.
[0099] In the implementation of the present disclosure, the target signal parameter may be a signal parameter corresponding to a digital signal that can be correctly decoded by an electronic device when transmitting a radio frequency signal of the current frequency and / or power.
[0100] In the disclosed embodiment, the digital signal transmitted under the interference of the target radio frequency signal transmitted based on the set target transmission parameters is scanned, and the corresponding correctly decoded target signal parameters and target transmission parameters are stored based on the scanning results.
[0101] In step S43, the above process is repeated to obtain a coexistence table matching the target radio frequency signal and the target application.
[0102] The coexistence table stores the correspondence between multiple target transmission parameters and multiple target signal parameters.
[0103] In the disclosed embodiment, by repeatedly setting the target transmission parameters and scanning to determine the target signal parameters corresponding to the target parameters, the target transmission parameters and the target signal parameters corresponding to the target transmission parameters are stored in the coexistence table.
[0104] In the disclosed embodiment, Figure 7 FIG. 1 is a flow chart showing a method of calibrating a signal parameter of a digital signal based on a radio frequency signal according to an exemplary embodiment. The calibration process may be performed by a manufacturer of the electronic device. Figure 7 As shown, after determining to start the calibration process, the RF transmission path of the RF signal is turned on. It can be understood that after the RF transmission path is turned on, the RF signal can be transmitted through the antenna or wirelessly to achieve data interaction between devices.
[0105] In the disclosed embodiment, the RF front-end module can set the frequency and power of the transmitted RF signal. There may be a corresponding relationship between the frequency of the transmitted RF signal and the power of the transmitted RF signal. For example, the starting frequency of the transmitted RF signal and the power corresponding to the starting frequency may be set, which may be the maximum power.
[0106] In the disclosed embodiment, a high-speed signal receiving path is opened, wherein digital signals can be transmitted through the high-speed signal receiving path.
[0107] In the disclosed embodiment, the signal parameters of the correctly decoded digital signal corresponding to the radio frequency signal can be determined by the test results of the parameter change (Shmoo) test. For example, the horizontal coordinate parameters and the vertical coordinate parameters of the Shmoo test can be set, and based on the horizontal coordinate parameters and the vertical coordinate parameter pairs, the digital signal interfered by the radio frequency signal of the current frequency and / or power is detected, so that the digital signal corresponding to the horizontal coordinate value and the vertical coordinate value that can be normally decoded under the interference of the radio frequency signal of the current frequency and / or power can be obtained, and the transmission parameters of the corresponding radio frequency signal and the parameters that the digital signal can be normally decoded are saved in the coexistence table.
[0108] In the embodiment of the present disclosure, the parameters for parameter change test may include a signal threshold decision threshold; and a clock sampling delay, wherein the signal decision threshold can be used as the vertical coordinate of the Shmoo test, and the clock sampling delay can be used as the horizontal coordinate of the Shmoo test.
[0109] In the implementation of the present disclosure, the digital signal may be a high-speed digital signal based on the mobile communication industry processor interface MIPI, for example, it may be a high-speed digital signal based on the D-PHY interface in MIPI, or it may be a high-speed digital signal based on the C-PHY interface in MIPI. Among them, D-PHY and C-PHY are interfaces used for communication in mobile devices, for example, physical interfaces used by cameras or screens.
[0110] In the implementation of the present disclosure, the test parameters of the Shmoo test are set as the signal threshold decision threshold; and the clock sampling delay. The signal decision threshold is used as the ordinate of the test result, the clock sampling delay is used as the abscissa of the test result, and the MIPI CPHY high-speed digital signal is used as the digital signal of the test. Figure 8-a , Figure 8-b as well as Figure 8-c are schematic diagrams showing a test result of a digital signal based on a radio frequency signal according to an exemplary embodiment. When there is no radio frequency signal influence, the following can be obtained: Figure 8-a The test results are shown in Figure 2. Figure 8-a When the digital signal is in the white background area, it means that the digital signal can be decoded normally under the clock sampling delay and signal threshold decision threshold. Figure 8-a When the gray background area is in the middle, it means that the digital signal cannot be decoded normally under the clock sampling delay and signal threshold decision threshold. When the frequency of the transmitted RF signal is set to the first frequency and the power is set to the first power, the following can be obtained: Figure 8-b The test results are shown in Figure 2. Figure 8-b When the digital signal is in the white background area, it means that the digital signal can be decoded normally under the clock sampling delay and signal threshold decision threshold. Figure 8-b When the background area is in the middle gray, it means that the digital signal cannot be decoded normally under the clock sampling delay and signal threshold decision threshold. When the frequency of the transmitted RF signal is set to the second frequency and the power is set to the second power, the RF signal corresponding to the second frequency and the second power has greater interference to the digital signal than the RF signal corresponding to the first frequency and the first power. Therefore, it can be obtained as follows Figure 8-c The test results are shown in Figure 2. Figure 8-c When the digital signal is in the white background area, it means that the digital signal can be decoded normally under the clock sampling delay and signal threshold decision threshold. Figure 8-c In the medium gray background area, it means that the digital signal cannot be decoded normally under the clock sampling delay and signal threshold decision threshold.
[0111] In the present disclosure, Figure 8-a , Figure 8-b as well as Figure 8-c In the Shmoo test result graph shown, the horizontal axis is limited by the total scan time. Figure 8-a , Figure 8-b as well as Figure 8-c The figure only shows the test results of the entire digital signal in a partial period, and the part not shown is basically symmetrically distributed.
[0112] In the embodiment of the present disclosure, if the MIPI CPHY high-speed digital signal is used as the digital signal for testing, Figure 9-a as well as Figure 9-b are schematic diagrams showing a test result of a digital signal based on a radio frequency signal according to an exemplary embodiment. When there is no radio frequency signal influence, the following can be obtained: Figure 9-a The test results are shown in Figure 2. Figure 9-a When the digital signal is in the white background area, it means that the digital signal can be decoded normally under the clock sampling delay and signal threshold decision threshold. Figure 9-a When the gray background area is in the middle, it means that the digital signal cannot be decoded normally under the clock sampling delay and signal threshold decision threshold. When the frequency of the transmitted RF signal is set to the third frequency and the power is set to the third power, the following can be obtained: Figure 9-b The test results are shown in Figure 2. Figure 9-b When the digital signal is in the white background area, it means that the digital signal can be decoded normally under the clock sampling delay and signal threshold decision threshold. Figure 9-b In the middle gray background area, it means that the digital signal cannot be decoded normally under the clock sampling delay and signal threshold decision threshold. Among them, the RF signal of the third frequency and the third power has a strong interference to the MIPI CPHY high-speed digital signal.

[0115] Fig.10 is a flow chart showing a method for determining a digital signal to be decoded according to an exemplary embodiment. Fig.10 As shown, the digital signal decoding method is used in an electronic device and includes the following steps.
[0116] In step S51, in response to detecting a first operation.
[0117] In step S52, a digital signal to be decoded is determined.
[0118] The first operation is used to determine a first application to be run, and the first application is an application that runs based on the decoded digital signal.
[0119] In an embodiment of the present disclosure, when the electronic device detects a first operation by a user, for example, when the electronic device detects that the user clicks a camera icon in the electronic device, the electronic device can determine that the first application to be run is an application corresponding to the camera module in the electronic device, thereby determining that the digital signal to be transmitted is a digital signal for implementing the corresponding function of the camera module.
[0120] In the disclosed embodiment, different applications to be run can implement the functions of the applications based on decoding different digital signals. Based on detecting different operations, the digital signals required for the application to be run can be determined. Therefore, the decoded digital signal can be determined by monitoring the user's first operation, and then the coexistence table corresponding to the digital signal can be retrieved based on the different digital signals, thereby ensuring correct decoding based on the current digital signal and the radio frequency signal.
[0121] In the embodiment of the present disclosure, when it is determined that the function module corresponding to the digital signal stops running, decoding of the digital signal is stopped.
[0122] Fig.11 is a flow chart of a method for stopping digital signal decoding according to an exemplary embodiment. Fig.11 As shown, the digital signal decoding method is used in an electronic device and includes the following steps.
[0123] In step S61, in response to the first application ending execution.
[0124] In the embodiment of the present disclosure, the first application may end running when the electronic device detects that the user exits the functional module corresponding to the digital signal. For example, the electronic device may detect that the user exits the camera module or the screen display module.
[0125] In step S62, the detection of the radio frequency signal transmitted by the electronic device is stopped, and the use of the signal parameter to decode the digital signal is stopped.
[0126] In the embodiment of the present disclosure, when the first corresponding operation ends, the electronic device stops detecting the RF signal transmitted by the RF front-end module of the electronic device, and stops decoding the digital signal using the signal parameters of the decoded digital signal corresponding to the RF signal.
[0127] In the embodiment of the present disclosure, when it is determined that the first application running based on the digital signal has ended its operation, the detection of the radio frequency signal emitted by the electronic device is stopped and the use of the parameters of the decoded digital signal corresponding to the current radio frequency signal to decode the digital signal is stopped, thereby avoiding excessive power consumption caused by real-time monitoring of the radio frequency signal by the electronic device.
[0128] In the disclosed embodiment, before the electronic device retrieves the coexistence table, it can detect whether the RF signal currently sent by the electronic device is present, and can detect whether the frequency and / or power of the RF signal currently sent by the electronic device interferes with the current digital signal.

[0130] In step S71, in response to the transmission power of the radio frequency signal being less than or equal to a threshold.
[0131] In step S72, the digital signal is decoded based on the default signal parameters.
[0132] In the embodiment of the present disclosure, when the electronic device detects that the transmission power and / or transmission frequency of the current radio frequency signal is less than or equal to the threshold of the corresponding digital signal, the threshold is the power and / or frequency of the radio frequency signal that interferes with the decoding of the current digital signal. Different digital signals may correspond to different thresholds.
[0133] In the embodiment of the present disclosure, when the electronic device detects that the transmission frequency and / or transmission power of the current radio frequency signal will not interfere with the decoding of the current digital signal, the digital signal is decoded based on the default signal parameters.
[0134] In the embodiment of the present disclosure, the default signal parameters may be signal parameters for decoding determined by relevant technical personnel based on the corresponding digital signal in the absence of interference with the radio frequency signal.
[0135] In the disclosed embodiment, when it is detected that the radio frequency signal will not interfere with the decoding of the digital signal, the digital signal can be decoded based on the default signal parameters, thereby enabling fast decoding of the digital signal and improving the user experience.
[0136] In the embodiment of the present disclosure, the digital signal may be a high-speed digital signal, wherein the high-speed digital signal may include a differential high-speed digital signal and a single-ended high-speed digital signal transmitted based on a MIPI interface.
[0137] In an embodiment of the present disclosure, the differential high-speed digital signal may include a MIPI high-speed digital signal, such as a MIPI DDPHY {Mobile Industry Processor Interface D-PHY (Physical)} differential signal, or a MIPI CPHY {Mobile Industry Processor Interface C-PHY (Physical)} differential signal.
[0138] In the disclosed embodiment, the signal parameters used to decode the digital signal may include a signal threshold decision threshold and a clock sampling delay. The signal threshold decision threshold is used to determine the high and low levels of the digital signal; the clock sampling delay can be used to determine the sampling position in the digital signal cycle. Fig.13 is a schematic diagram showing a method for determining a signal parameter of a digital signal according to an exemplary embodiment. Fig.13 As shown, the digital signal 9 is a digital signal that is not interfered by the radio frequency signal. The digital signal 9 can be sampled at a time delay of t1, and the signal threshold at which the digital signal 9 can be decoded is v1. Fig.14 is a schematic diagram showing a method for determining a signal parameter of a digital signal according to an exemplary embodiment. Fig.14 As shown, the digital signal 10 is a digital signal after the digital signal 9 is interfered by the radio frequency signal. Based on the frequency and / or power of the digital signal and the currently transmitted radio frequency signal, the signal threshold decision threshold at which the current digital signal 10 can be normally decoded is determined through the coexistence table; and the clock sampling delay. For example, Fig.14 As shown, the digital signal 10 can be decoded normally based on the re-determined clock sampling delay t2 and the signal threshold decision threshold v2.
[0139] In the embodiments of the present disclosure, the digital signal decoding method is described in conjunction with the following examples.
[0140] In the disclosed embodiment, Fig.15 The figure is a schematic diagram showing a digital signal decoding method flow according to an exemplary embodiment. Fig.15It can be a process of electronic equipment based on user-side use. After starting, a detection action is performed before the interfered high-speed signal function module to determine whether there is RF transmission at the same time and the RF transmission power reaches the interference power value. If there is no RF transmission, the inherent decision threshold and clock sampling delay settings of the high-speed digital signal are called. If RF transmission is detected and the power value reaches the interference problem, the currently used RF transmission frequency and power are called from the system, and the corresponding digital signal decision threshold and clock signal sampling delay are searched and retrieved from the coexistence table, and changes are made according to the information in the coexistence table. If changes in RF frequency and power transmission are detected, the table is searched and the information is retrieved based on the coexistence table, and the settings are updated. If there is no change, the current settings are maintained. If the high-speed digital signal exits the corresponding function module, this process ends.
