中文说明： 考虑雨衰 阴影 和多径影响，使用高阶累积量对MPSK信号进行调制识别，FIR 底通和带通滤波器和IIR 底通和带通滤波器，本程序的性能已经达到较高水平，使用起来非常方便，信号处理中的旋转不变子空间法。
English Description：
Consider shadow of rain attenuation effect and Multipath, modulation recognition using higher order cumulants of MPSK signals, end of FIR-pass and band-pass filter and IIR-pass and band-pass filter at the end of this program has reached a higher level of performance, is easy to use, rotation-invariant subspace methods in signal processing.
