平坦度的补偿方法和装置、存储介质和电子设备Flatness compensation method and device, storage medium and electronic device

技术领域technical field

背景技术Background technique

在通信领域中，随着4G/5G的应用，无线电收发信机的工作频带越来越宽，达到了几百兆赫兹。在如此宽的频率范围内，射频器件的增益平坦度难以得到保证。需要采用滤波器对基带信号进行增益预补偿来解决设备硬件由于增益不平衡造成的带内增益不平坦问题。相关技术中，可以使用常规的IFFT或训练的方法进行滤波器生成，然后使用生成的滤波器进行增益预补偿，但是，采用IFFT或训练的方法生成的滤波器，对基带信号的补偿效果较差，并且通过这种方式成长的滤波器通常无法准确地评估补偿后的带内平坦度峰-峰值。因此，针对相关技术中，通过常规的IFFT或训练的方法生成的滤波器对基带信号进行预补偿，存在补偿效果差的问题，尚未提出有效的技术方案。In the field of communications, with the application of 4G/5G, the operating frequency band of radio transceivers is getting wider and wider, reaching several hundred megahertz. In such a wide frequency range, it is difficult to guarantee the gain flatness of RF devices. It is necessary to use a filter to pre-compensate the gain of the baseband signal to solve the problem of in-band gain unevenness caused by the unbalanced gain of the device hardware. In the related art, conventional IFFT or training methods can be used to generate filters, and then the generated filters can be used to perform gain pre-compensation. However, filters generated by IFFT or training methods have poor compensation effects on baseband signals. , and filters grown in this way often cannot accurately assess the compensated in-band flatness peak-to-peak. Therefore, in the related art, the pre-compensation of the baseband signal by the filter generated by the conventional IFFT or training method has the problem of poor compensation effect, and an effective technical solution has not been proposed.

下面结合一可选示例对平坦度的补偿方法的流程进行说明，如图3所示，该方法可以包括以下步骤：The flow of the flatness compensation method will be described below with reference to an optional example. As shown in FIG. 3 , the method may include the following steps:

需要说明的是，接收机和发射机的测试步骤中要求测试间隔频率＝基带信号采样率/抽头系数数量，为了减少资源消耗，当抽头系数数量较少时，测试间隔较大，测试数据无法反应带内增益的高频波动，细节丢失，最终导致补偿性能下降。采用IFFT或训练的方法生成的滤波器通常无法准确地评估补偿后的带内平坦度峰-峰值。因此，需要找到更加合适的抽头系数，才能使补偿性能更好，更好的评估补偿后的带内平坦度峰-峰值。It should be noted that in the test steps of the receiver and transmitter, the test interval frequency = baseband signal sampling rate/number of tap coefficients is required. In order to reduce resource consumption, when the number of tap coefficients is small, the test interval is large, and the test data cannot be reflected. High-frequency fluctuations in in-band gain, loss of detail, and ultimately degraded compensation performance. Filters generated using IFFT or training methods often cannot accurately assess compensated in-band flatness peak-to-peak. Therefore, it is necessary to find a more suitable tap coefficient to make the compensation performance better and to better evaluate the peak-to-peak value of the in-band flatness after compensation.

步骤1，设置滤波器抽头数。可选地，根据硬件资源消耗选择合适的滤波器抽头系数数量N，其中N为大于等于2的整数。Step 1, set the number of filter taps. Optionally, an appropriate number N of filter tap coefficients is selected according to hardware resource consumption, where N is an integer greater than or equal to 2.

步骤2，设置进行补偿的射频频率区间R。可选地，R可以是单个区间，也可能是多个区间。R满足R∈[Fc–Fs/2,Fc+Fs/2]，其中Fc为射频中心频点，Fs为基带信号采样率。Step 2, setting the radio frequency range R for compensation. Optionally, R can be a single interval or multiple intervals. R satisfies R∈[Fc–Fs/2,Fc+Fs/2], where Fc is the center frequency of the radio frequency, and Fs is the baseband signal sampling rate.

步骤3，增益曲线测量。可选地，以基带信号DC对应的射频频点Fc为原点，以Fs/(N*K)为过采样间隔，测试频率区间[Fc–Fs/2，Fc+Fs/2)共N*K个采样点的增益值。测得的增益值按照频率从小到大排列得到序列G(n)＝{g(0),g(1),…,g(N*K–1)}，其中，增益值的单位为Db，K为过采样倍数。Step 3, gain curve measurement. Optionally, with the radio frequency point Fc corresponding to the baseband signal DC as the origin, with Fs/(N*K) as the oversampling interval, the test frequency interval [Fc–Fs/2, Fc+Fs/2) is N*K in total gain value for each sample point. The measured gain values are arranged in ascending order of frequency to obtain a sequence G(n)={g(0),g(1),...,g(N*K–1)}, where the unit of the gain value is Db, K is the oversampling factor.

步骤4，设置增益参考值T。可选地，参考值T即期望的平坦的链路增益值。Step 4, set the gain reference value T. Optionally, the reference value T is the desired flat link gain value.

步骤5，生成偏差序列C(n)。可选地，按照以下公式生成偏差序列C(n)：Step 5, generate a deviation sequence C(n). Optionally, the deviation sequence C(n) is generated according to the following formula:

其中，f(n)为G(n)序列中元素索引与基带信号的射频频点的映射函数，偏差序列是补偿滤波器响应的目标参考。T是增益参考值，即期望的平坦的链路增益值。A为目标滤波器的期望阻带增益，通常根据滤波器抽头数进行设置，一般可通过公式A＝-10*log2(N)进行设置。Among them, f(n) is the mapping function between the element index in the G(n) sequence and the radio frequency frequency of the baseband signal, and the deviation sequence is the target reference for compensating the filter response. T is the gain reference value, ie the desired flat link gain value. A is the desired stop-band gain of the target filter, which is usually set according to the number of filter taps. Generally, it can be set by the formula A=-10*log2(N).

步骤6，生成初始修正序列D(n)。可选地，D(n)为偏差序列的子序列，其中，C(n)是D(n)的K倍，从C(n)中选择一部分出来值可以得到D(n)。Step 6: Generate an initial correction sequence D(n). Optionally, D(n) is a subsequence of the deviation sequence, where C(n) is K times D(n), and D(n) can be obtained by selecting a part of the values from C(n).

步骤7，生成优化修正序列O(n)。可选地，优化修正序列O(n)的生成方法具体如下：步骤(1)迭代器输入为长度为N的修正序列B(n)，其中，B(n)的初始序列为上述初始修正序列D(n)。步骤(2)引入N*N的扰动矩阵P，M定义如下：Step 7, generate an optimized correction sequence O(n). Optionally, the generation method of the optimized correction sequence O(n) is specifically as follows: Step (1) The iterator input is a correction sequence B(n) of length N, wherein the initial sequence of B(n) is the above-mentioned initial correction sequence. D(n). Step (2) introduces a perturbation matrix P of N*N, and M is defined as follows:

其中，STEP为搜索迭代算法的步长，I _N为N*N的单位矩阵。 Among them, STEP is the step size of the search iterative algorithm, and IN is the unit matrix of _N *N.

步骤(3)对P，M矩阵每一行中的元素进行滤波器转换，并计算其偏差值E，其结果分别存入对应结果矩阵Rp以及Rm的对应行中。结果矩阵大小为1*N。Step (3) Perform filter conversion on the elements in each row of the P and M matrices, and calculate the deviation value E, and store the results in the corresponding rows of the corresponding result matrices Rp and Rm respectively. The resulting matrix size is 1*N.

步骤(4)比较并获得Rp以及Rm中最小的单元，作为当前迭代的偏差值输出。取最小值对应矩阵的对应行元素序列作为迭代输出修正序列R(n)。Step (4) compares and obtains the smallest unit in Rp and Rm, and outputs it as the deviation value of the current iteration. The corresponding row element sequence of the matrix corresponding to the minimum value is taken as the iterative output correction sequence R(n).

需要说明的是，上述步骤(1)～(4)中的迭代步长可以按照以下方式设置：通过将迭代输出的R(n)传递给迭代输入B(n)可通过多次循环上述步骤(1)～(4)得到优化修正序列O(n)以及最终偏差值Ef。迭代可以改变步长值进行多段执行，例如STEP＝0.1迭代一定次数后采用更小的步长0.01再进行迭代，从而优化收敛速度与性能。It should be noted that the iterative step size in the above steps (1) to (4) can be set in the following manner: by passing the iterative output R(n) to the iterative input B(n), the above steps ( 1) to (4) obtain the optimized correction sequence O(n) and the final deviation value Ef. The iteration can change the step size for multi-stage execution. For example, STEP = 0.1 after a certain number of iterations, use a smaller step size of 0.01 to iterate again, so as to optimize the convergence speed and performance.

可选地，在确定优化修正序列O(n)的过程中，收敛条件可以按照以下方式设置：1、固定迭代次数；2、迭代一定次数后偏差值E不再发生显著变化(如小于设定阈值)；3、偏差值E达到***预期。Optionally, in the process of determining the optimization correction sequence O(n), the convergence conditions can be set in the following ways: 1. The number of iterations is fixed; 2. The deviation value E does not change significantly after a certain number of iterations (for example, it is less than the set value). threshold); 3. The deviation value E reaches the system expectation.

可选地，滤波器转换方法如下：假设输入为修正序列O(n)，输出为滤波器抽头系数H(n)，长度均为N。Optionally, the filter conversion method is as follows: it is assumed that the input is a correction sequence O(n), the output is the filter tap coefficient H(n), and the lengths are all N.

将以Db为单位的修正序列O(n)转化为线性修正序列L(n)。Convert the correction sequence O(n) in Db into a linear correction sequence L(n).

可选地，以下详述如何生成偏差值：Optionally, the following details how the bias value is generated:

输入为滤波器抽头系数H(n)，偏差序列C(n)，输出为偏差值E，偏差值越小代表滤波器抽头系数的补偿效果越好，生成方法如下：The input is the filter tap coefficient H(n), the deviation sequence C(n), and the output is the deviation value E. The smaller the deviation value, the better the compensation effect of the filter tap coefficient. The generation method is as follows:

S1，对H(n)进行补0，得到新的序列K(n)，具体公式如下：S1, fill H(n) with 0 to obtain a new sequence K(n). The specific formula is as follows:

S2，对K(n)执行K*N点DFT处理，得到序列P(n)，具体公式如下：S2, perform K*N point DFT processing on K(n) to obtain the sequence P(n), the specific formula is as follows:

M(n)＝20*log ₁₀(|Q(n)|) n＝0，1，...，NK-1； M(n)=20*log ₁₀ (|Q(n)|) n=0, 1, ..., NK-1;

M(n)是该滤波器系数H(n)在S3中各采样点上的增益补偿值，并且按照频率从小到大进行排列。M(n) is the gain compensation value of the filter coefficient H(n) at each sampling point in S3, and is arranged in ascending order of frequency.

S5，计算补偿偏差序列E(n)，该序列反应了该滤波器在各频点上的补偿残差，具体公式如下：S5, calculate the compensation deviation sequence E(n), which reflects the compensation residual error of the filter at each frequency point, and the specific formula is as follows:

S6，计算偏差值E＝Max(E(n))–Min(E(n))；S6, calculate the deviation value E=Max(E(n))−Min(E(n));

利用偏差值序列E(n)中的最大值减去最小值即得到偏差值。The deviation value is obtained by subtracting the minimum value from the maximum value in the deviation value sequence E(n).

步骤8，生成滤波器抽头系数。Step 8, generate filter tap coefficients.

利用步骤7中介绍滤波器转换方法对O(n)进行滤波器转换得到最终FIR滤波器的抽头系数。Use the filter transformation method introduced in step 7 to perform filter transformation on O(n) to obtain the tap coefficients of the final FIR filter.

步骤9，生成补偿曲线。Step 9, generate a compensation curve.

取迭代结束时的T–E(n)形成的序列即代表了补偿后***增益的预期曲线，得到的E即补偿后***平坦度峰-峰值的评估值。The sequence formed by taking the T–E(n) at the end of the iteration represents the expected curve of the system gain after compensation, and the obtained E is the evaluation value of the peak-to-peak value of the system flatness after compensation.

通过本实施例，在FIR滤波器抽头系数不变、以及导致的硬件资源消耗不变的情况下，通过上述方式得到的滤波器抽头系数能获得更好的补偿效果，通过过采样间隔获取更多的基带信号的信息，对这些信息进行综合处理，使用迭代的算法，找一个更合适的滤波器抽头系数，在最终生成的滤波器抽头系数不变的情况下，能够拥有更好的曲线，最终得到更能够补偿曲线的滤波器，提高了补偿效果。Through this embodiment, under the condition that the tap coefficients of the FIR filter remain unchanged and the resulting hardware resource consumption remains unchanged, the filter tap coefficients obtained in the above manner can obtain a better compensation effect, and the oversampling interval can obtain more The information of the baseband signal is comprehensively processed, and an iterative algorithm is used to find a more suitable filter tap coefficient. Under the condition that the final generated filter tap coefficient is unchanged, it can have a better curve, and finally A filter more capable of compensating the curve is obtained, which improves the compensation effect.
