中文说明：相关分析过程的matlab方法，使用高阶累积量对MPSK信号进行调制识别，随机调制信号下的模拟ppm，采用的是脉冲对消法，已调制信号计算其普相关密度，单径或多径瑞利衰落信道仿真。
English Description：
Correlation analysis method of MATLAB, using higher order cumulants of MPSK signal modulation recognition, stochastic simulation of modulation signals ppm, using a pulse cancellation method has been calculated using relative density modulation signal, single-diameter/multipath Rayleigh fading channel simulation.
