中文说明：加入重复控制，FIR 底通和带通滤波器和IIR 底通和带通滤波器，主同步信号PSS在时域上的相关仿真，是国外的成品模型，仿真效果非常好，使用高阶累积量对MPSK信号进行调制识别。
English Description：
Repetitive control is introduced, at the bottom of the fir pass and band-pass filter and IIR bottom pass and band-pass filter, a primary synchronization signal (PSS) in the time domain simulation, is foreign product model, the simulation effect is very good, using high order cumulants for modulation recognition of MPSK signals.
