统计信号分析与处理代码，多多益善。统计信号建模方法，有用文献。(Statistical signal analysis and processing code, the more the better. Statistical modeling method, useful document.)

i am a student. I want matlab and simulink programs according to my project.

说明：  function [Sx,f,alpha] = Sa(s,fs,M,N,read_f,del_f) 计算信号的循环谱 [Sx,f,alpha] = Sa(s,fs,M,N,read_f,del_f) 输入： s 序列 fs 采用频率 M 滑动频率窗长 N fft计算点数 read_f 可视频率（一般为载频的整数倍） del_f 可视频率间隔 输出： Sx 信号的循环谱 f 频率轴 alpha 循环频率轴(Cyclosationary Spectrum)

说明：  基本的遗传算法实现，并举了一个简单的例子，编程语言matlab(Basic genetic algorithm, both a simple example, programming language matlab)
