PCA

中文的OFDM原理，讲的很好，很仔细，对初学者有很好的帮助(Chinese OFDM principle, speak very good, very carefully, and have very good help for beginners)

图形图像 匹配。当有两个图像时，程序计算一个图像的不变量，然后跟两一个图像比对，然后输出他们是否匹配。(This codes are for images matching when you have two or more images taken under different lighting, rotation...)

基于MATLAB的语音信号分析与处理。 录制一段自己的语音信号，用窗函数法和双线性变换进行滤波器，并对滤波前后的信号进行对比；回放语音信号。 (MATLAB-based voice signal analysis and processing. Record a voice signal, window function method and the bilinear transform filter, and before and after filtering the signal contrast playback voice signal.)

实现基于主分量的svm分类器.很不错的东东(svm based on primal.)

rbf neural network approximation

说明：  短时傅立叶变换程序，可得信号时频曲线,希望对大家有所帮助(Short time Fourier transform procedure can be time-frequency curve, we hope to help)

mimo信道stpc编码仿真 数字是收发天线数 (MIMO STPC channel coding simulation digital transceiver antenna number is )

离散正交多项式拟合例子，可自定义离散正交多项式次数。附有简单清晰的说明。(Examples of discrete orthogonal polynomial fitting)

this is a matlab program modulate to a wireless or wire line chanel

this is an implementation of ldpc encoder and decoder in matlab. generator matrix, parity check matrix and the chennel are implemented seperately. the bit error rate performance is estimated for the ldpc code
