The controller quickly performs compensation according to the target compensation parameter in the current compensation information query table; or, through an iterative algorithm, starting from preliminary compensation parameters, gradually adjusts the compensation parameters according to the compensation information and compensation effect feedback until the best compensation effect is achieved. This method may be more time-consuming, but can provide more optimized compensation parameters.

[0048] In the technical solution provided in the above step S208, the target compensation parameter is used to instruct the compensator to compensate for the received signal. The target compensation parameter includes but is not limited to the impulse response sequence of the digital filter, or other parameters of the digital filter, such as cutoff frequency, quality factor (Q value), bandwidth, etc., and can also be a gain adjustment value (this is the most direct and common parameter of the compensator, used to instruct the compensator to increase or decrease the amplitude of the signal at a specific frequency point. The gain adjustment value can be a simple multiplication factor or a complex function that changes with frequency), etc., and the present application does not make specific limitations on this.

The higher the order, the more complex the design of the compensator, which may include more filter coefficients and more complex mathematical operations. A high-order filter usually requires more computing resources and storage space, but it can also provide more sophisticated frequency response control and more accurate compensation effects. The order of the compensator is directly related to its frequency resolution. The higher the order, the better the frequency resolution, and the compensator can more accurately control the gain or phase of the signal at different frequency points, which is particularly important for applications that require precise compensation at specific frequencies.

[0055] Optionally, in the embodiment of the present application, including but not limited to, the sampling rate may be selected to be 100Mhz, and the order N of the compensator may be selected to be 11, in which case the compensation resolution of the compensator is 100Mhz / (11-1)=10Mhz.

[0056] Optionally, in an embodiment of the present application, the spare compensation point is used to indicate the compensation point at which the compensator can directly control the degree of compensation, and the degree of compensation of the signal by other compensation points within the compensator range except the spare compensation point is affected by the spare compensation point and the compensation coefficient corresponding to the spare compensation point.

[0057] Optionally, in an embodiment of the present application, including but not limited to, the sampling rate can be selected as 100Mhz, and the order N of the compensator can be selected as 13.

[0058] As an optional implementation, a target compensation point and a compensation coefficient corresponding to the target compensation point are determined based on multiple backup compensation points and compensation information, including: screening the backup compensation points that fall within a reference compensation range to obtain the target compensation point, wherein the reference compensation range is the frequency range in which the reference signal is to be compensated for fluctuations, and the compensation information includes the reference compensation range; extracting a target difference parameter corresponding to the target compensation point from the compensation information, wherein the target difference parameter is used to indicate the difference between the signal strength of the reference signal detected at the target compensation point and the standard signal strength of the reference signal; and determining the compensation coefficient based on the target difference parameter.

[0059] Optionally, in an embodiment of the present application, it includes but is not limited to directly determining the spare compensation point that falls within the reference compensation range of the reference signal as the target compensation point, that is, directly determining the spare compensation point that has the compensation requirement among the spare compensation points of the reference signal as the target compensation point. In order to further optimize the compensation effect, after the spare compensation points that fall within the reference compensation range are screened to obtain the target compensation point, the spare compensation points closest to the target compensation point on both sides are determined as auxiliary compensation points. For example, when the sampling rate is selected to be 100Mhz and the order N of the compensator is selected to be 13, if the compensator gain of the frequency point 8.33*3Mhz is screened out to be raised, that is, the spare compensation point corresponding to the frequency point 8.33*3Mhz is the target compensation point, then the spare compensation points corresponding to the two frequency points 8.33*2Mhz and 8.33*4Mhz can be determined as auxiliary compensation points. This approach can better control the change of gain and better control the compensation effect of multiple frequency bands.

[0060] Optionally, in an embodiment of the present application, the target difference parameter is used to indicate the difference between the signal strength of the reference signal detected at the target compensation point and the standard signal strength of the reference signal, where the standard signal strength is the signal strength of the reference signal before it is affected by the analog link, including but not limited to being fixed at all frequencies, or different at different frequencies, but all known or detectable.

[0062] As an optional implementation, a target compensation point and a compensation coefficient corresponding to the target compensation point are determined based on multiple backup compensation points and compensation information, including: inputting multiple backup compensation points and compensation information into a compensation model, wherein the compensation model maintains compensation effect parameters when different target compensation points and different compensation coefficients are used to compensate for signal strength fluctuations of a reference signal at the target compensation point, the compensation effect parameters are used to indicate the degree of proximity between the signal strength of the compensated reference signal and the standard signal strength of the reference signal, and the compensation model is used to output the backup compensation point and the corresponding compensation coefficient that are closest to the degree of proximity indicated by the compensation effect parameters; receiving the backup compensation point output by the compensation model as the target compensation point, and receiving the compensation coefficient corresponding to the backup compensation point output by the compensation model as the compensation coefficient of the target compensation point.

[0063] Optionally, in an embodiment of the present application, the compensation model may be, but is not limited to, a pre-trained machine learning model, such as a neural network, for predicting compensation effect parameters under different compensation points and different compensation coefficient combinations. With the aid of the compensation model, the controller may be used to process signal strength fluctuation information, input the backup compensation point and compensation information into the compensation model, and receive the result output by the model. The compensator adjusts the signal according to the target compensation point and compensation coefficient provided by the controller. The training and use phases of the compensation model include:

[0064] Data collection phase: In the early stage, a large number of reference signal samples output by the analog link are collected, as well as the fluctuation information of these signals at the backup compensation points.

[0065] Model training phase: Use the collected data to train the compensation model. The input of the model is the backup compensation point and compensation information, and the output is the compensation effect parameter, which reflects the closeness between the reference signal strength after compensation and the standard signal strength. The model can predict the optimal compensation point and compensation coefficient by learning the effect parameters under different compensation strategies.

[0066] Real-time compensation stage: In actual applications, the controller detects the fluctuation information of the reference signal in real time and inputs it into the compensation model together with the backup compensation points.

[0067] Model output: Based on the compensation effect parameters learned internally, the compensation model outputs the closest backup compensation point and the corresponding compensation coefficient, that is, the target compensation point and the target compensation coefficient.

[0068] Among them, the compensation model can be a deep learning model, such as a convolutional neural network (CNN) or a long short-term memory network (LSTM), which is trained to identify and predict the optimal strategy for fluctuation compensation. The compensation effect parameter can be a mean square error (MSE), a root mean square error (RMSE) or a correlation coefficient, etc., which is used to quantify the difference between the compensated signal strength and the standard signal strength.

[0069] Optionally, in an embodiment of the present application, not all frequency points corresponding to target compensation points output by the compensation model are necessarily within the frequency range of the reference signal for which fluctuation compensation is to be performed.

[0070] As an optional implementation, the target compensation parameters are configured to the compensator, including: extracting the initial operating parameters corresponding to the target compensation points from the multiple initial operating parameters according to the correspondence between the multiple backup compensation points and the multiple initial operating parameters included in the initial operating sequence of the compensator to obtain the operating parameters to be adjusted, wherein the initial operating sequence is used to indicate the compensation mechanism of the compensator for the signal passing through the compensator; extracting the frequency domain parameters to be adjusted corresponding to the operating parameters to be adjusted from the multiple reference frequency domain parameters included in the reference frequency domain sequence obtained after Fourier transforming the initial operating sequence; calculating and updating the frequency domain parameters according to the frequency domain parameters to be adjusted and the compensation coefficients; replacing the frequency domain parameters to be adjusted in the reference frequency domain sequence with the updated frequency domain parameters to obtain the target frequency domain sequence; performing an inverse Fourier transform on the target frequency domain sequence to obtain the target operating sequence; updating the initial operating sequence configured by the compensator to the target operating sequence, and the compensator is used to perform fluctuation compensation for the signal according to the compensation mechanism for the signal passing through the compensator indicated by the target operating sequence.

[0071] Optionally, in an embodiment of the present application, including but not limited to selecting a filter as a compensator, the initial operation sequence of the compensator may be coef_init=[0,0,0,0,0,0,1,0,0,0,0,0,0,0], which means that in the initial design when the compensator does not compensate any signal, it is an ideal all-pass filter, and the order N of the compensator is 13. Figure 5 is an impulse response of an ideal all-pass filter according to an embodiment of the present application, Figure 6 is the frequency domain response of an ideal all-pass filter according to an embodiment of the present application, such as Figure 6As shown, the characteristic of an ideal all-pass filter is to keep the amplitude of the signal unchanged at all frequencies, that is, the gain is 1 (0dB), without increasing or attenuating the gain, but it will change the phase of the signal. According to the sampling rate of the channel (that is, the sampling rate of the signal converter) 100Mhz, it can be concluded that the frequency points corresponding to the spare compensation points are -8.33*6Mhz, -8.33*5Mhz, -8.33*4Mhz, -8.33*3Mhz, -8.33*2Mhz, -8.33Mhz, 0Mhz, 8.33Mhz, 8.33*2Mhz, 8.33*3Mhz, 8.33*4Mhz, 8.33*5Mhz, 8.33*6Mhz. The initial operating parameters corresponding to the target compensation points are determined according to the corresponding relationship between the spare compensation points and multiple initial operating parameters. In the example, the middle point of coef_init can be regarded as the "center" of the frequency response, and there is a mapping relationship between the position of each element in coef_init and the frequency point in the frequency domain. Since coef_init is a symmetrical sequence (ideal all-pass filter), coef_init(3) corresponds to the third frequency point 8.33*3MHz in the positive direction, and coef_init(10) corresponds to the third frequency point -8.33*3MHz in the negative direction. This is because N is 13, so coef_init(13-k) corresponds to the negative frequency point of coef_init(k). That is, when the 8.33*3Mhz frequency needs to be compensated for fluctuations, it can be determined that the initial operating parameter corresponding to the target compensation point is coef_init(3). The reference frequency domain sequence is obtained by Fourier transforming the initial operating sequence, that is, performing a fast Fourier transform (FFT) on coef_init to obtain the frequency domain information of 13 points (that is, the reference frequency domain sequence) FFT_INT:

[0072] FFT_INT=

[0073] [1.00000000000000+0.00000000000000i,

[0074] -0.970941817426052-0.239315664287558i,

[0085] -0.970941817426052+0.239315664287558i];

[0086] It is then determined that the frequency domain parameter to be adjusted is FFT_INT(3), and then the updated frequency domain parameter is calculated based on the frequency domain parameter to be adjusted and the compensation coefficient. For example, the compensation coefficient can be 1.2, which means that the signal strength of the frequency point needs to be enhanced by 1.2 times, or it can be expressed as 1.58dB (20log(1.2)=1.58dB), which means that the signal gain of the frequency point needs to be increased by 1.58dB. Then, the updated frequency domain parameter can be calculated as FFT_INT'(3)=FFT_INT(3)*1.2. In order to optimize the compensation effect, the auxiliary frequency domain parameters of the surrounding frequency points (i.e., auxiliary compensation points) are also calculated as FFT_INT'(2)=FFT_INT(2)*1.1 and FFT_INT'(4)=FFT_INT(4)*1.2. The updated frequency domain parameters are used to replace the frequency domain parameters to be adjusted in the reference frequency domain sequence. In order to optimize the compensation effect, the obtained auxiliary frequency domain parameters can be used to replace the original frequency domain parameters in the reference frequency domain sequence corresponding to the auxiliary frequency domain parameters to obtain the target frequency domain sequence FFT_INT'. After performing an inverse Fourier transform on the target frequency domain sequence, the target operating sequence Coef_update = ifft(FFT_INT') can be obtained. The target operating sequence may include complex numbers. Figure 7This is the frequency domain response of the filter after adjusting the running sequence according to the embodiment of the present application. It can be seen that the filter can have different effects on the amplitude of the signal at different frequencies. Therefore, the values ​​of FFT_INT at different positions can be adjusted to reversely compensate for the in-band fluctuations in the analog domain, thereby achieving very small in-band fluctuations.

[0088] Optionally, in an embodiment of the present application, the standard signal strength of the reference signal includes but is not limited to being constant for different frequencies, or different frequencies may correspond to different signal strengths, but it is clear that the standard signal strength of the reference signal is the signal strength of the reference signal when it is not affected by the analog link. By comparing the reference signal strength and the standard signal strength at each frequency, it is possible to detect which frequencies' signal strengths are affected by the analog link and the specific degree of impact, and then determine which frequency points require fluctuation compensation and how much fluctuation compensation is required.
