中文说明： 基于互功率谱的时延估计，保证准确无误，是学习通信的好帮手，使用高阶累积量对MPSK信号进行调制识别，连续相位调制信号(CPM)产生，自写曲率计算函数 ,具有丰富的参数选项。
English Description：
Time delay estimation based on cross power spectrum ensures accuracy and is a good helper for learning communication. It uses high-order cumulant for modulation identification of MPSK signal, generates continuous phase modulation signal (CPM), writes curvature calculation function, and has rich parameter options.
