Rayleigh fading channel with Alamouti Space Time Block Coding for matlab simulation

本代码包含了多个MATLAB经典程序，其中有：滤波器，线性变换，图像处理等(This code contains a number of MATLAB classical procedures, including: filters, linear transform, image processing, etc.)

说明：  一个雷达回波模拟的matlab程序包,含有在RCS服从卡方分布,瑞利分布(A matlab program package of radar echo simulation, including the distribution of RCS obeying chi square distribution and Rayleigh distribution)

时频分析的小帮手，里面对基本的时频分析程序有了比较详细的论述(Time-frequency analysis of the Companion, which the basic time-frequency analysis program with a more detailed exposition)

自己编的5种调制信号，借鉴了主成分分析算法（PCA），用于信号特征提取、信号消噪。( Own five modulation signal, It draws on principal component analysis algorithm (PCA), For feature extraction, signal de-noising.)

说明：  你可以用这个程序通过一个巴特沃兹滤波器产生有色噪声，并求出噪声的波形和功率谱。(You can use this program through a Butterworth filter produces colored noise and find the noise waveform and power spectrum.)
