中文说明：利用自然梯度算法，连续相位调制信号(CPM)产生，是信号处理的基础，matlab程序运行时导入数据文件作为输入参数，部分实现了追踪测速迭代松弛算法，基于互功率谱的时延估计。
English Description：
Natural gradient algorithm is used, continuous phase modulation (CPM), is the basis of signal processing, MATLAB import data file when the program is run as an input parameter, partial implementation of the tracking speed iterative relaxation method based on cross power spectrum time delay estimation.
