用改进SVM实现人脸特征提取和识别，用matlab编写，和结果分析(A matlab code of enhanced SVM for face recognition)

signal processing about OFDM simulation

内包含频域滤波的步骤及MATLAB代码，是频域增强中所必须知道的哦，还有一个用巴特沃思滤波器效果的例子。(Contains the frequency domain filtering steps and MATLAB code, is enhanced in the frequency domain needs to know Oh, and a Butterworth filter with the effect of example.)

说明：  BEA的一些相关资料，对于初学入门的人是比较不错的(BEAs some relevant information, for beginners to get into a good person is more)

It is 27 level asymmetrical multilevel inverter

ofdm在matlab上的仿真程序，并且是可视化的matlab程序(ofdm simulation)

说明：  该程序是一位同学写的，运行该程序需要rtlSDR设备，便宜一点的淘宝不到100元，插上rtlsdr后，配置好matlab环境，能够实现扫描25M-1.75GHz的当地频谱，当然也可以自行修改范围(rtlsdr rx specsweeep 25MHz~175MHz)

用监督参数估计中的贝叶斯方法估计条件概率密度的参数u(With the supervision of the Bayesian estimation method to estimate the parameters of the conditional probability density of u)

能够很好的实现hilbert变化，结果和matlab基本一样，很实用(it Can very good realize Hilbert change, results and matlab are basic and same, very practical )
