用短时傅立叶变换对信号进行时频分析，并有频谱图随着窗的大小进行的对比。(Using short-time Fourier transform of the signal time-frequency analysis and frequency spectrum as the window size of the contrast.)

两本PDF格式电子书，是关于s-function编写的。内容很全面。(Two PDF format e-books, is about the s-function written. Content is very comprehensive.)

This program simulates the bit-error-rate (BER) performance of OSTBC with L=4 antennas over the frequency flat Rayleigh block fading channel The code is developed for real orthogonal design, code rate 1/2 modulation- 16 QAM with gray coding resulting in 2 bits/sec/Hz.(This program simulates the bit-error-rate (BER) performance of OSTBC with L = 4 antennas over the frequency flat Rayleigh block fading channel The code is developed for real orthogonal design, code rate 1/2 modulation-16 QAM with gray coding resulting in 2 bits/sec/Hz.)

主要研究了比较经典的直接加窗加权旁瓣抑制技术，并利用Matlab进行了仿真，给出了对线性调频信号和 相位编码信号脉冲压缩旁瓣抑制的直接加窗加权法处理结果，得出了分析结论。(Mainly studied the classical direct windowed weighted sidelobe suppression techniques, and using the Matlab simulation, given a linear FM signal and The phase-encoded signal pulse compression sidelobe suppression of the direct plus window weighting method the results of the analysis conclusions.)

进行方差分析的MATLAB源码，源文件中有用法。网络下载的，非原创。有兴趣的朋友一起讨论。(variance analysis of MATLAB source, a source usage. Download the network, non-originality. Interested friends together.)
