建立cdma蜂窝小区模型（分成小区内用户和区外用户），对初次接触CDMA信道模型编码的初学者，有很大的指导作用(Building cdma cellular cell model (divided residential users in and outside users), on the initial contact with CDMA channel model coding beginner, there is a great guide)

这是放大10倍后的用数值微分法生成直线的程序(This is the enlarged 10 times the numerical differential method to create line procedures)

A Novel Filter-Bank Multicarrier Scheme to Mitigate the Intrinsic Interference-Application to MIMO Systems

此代码为摄像机标定程序，是用Tsai方法进行标定，在MATLAB环境下编辑(this code for the camera calibration procedures, Tsai method is used for calibration in MATLAB Environment Editor)

这个程序是用来仿真多小区多用户，已知信道信息，采用OFDM，QPSK调制下的误码性能分析，特点是将预编码参数放在频域处理。(This program is used to simulate multi-user multi-cell, known channel information, using OFDM, QPSK modulation BER performance under analysis, is characterized by the pre-coding parameters on the frequency domain.)

harris 可用于提取影像特征点，以用于影像匹配(harris corner detection)

svm分类程序，经过调试，对初学者很有用的(svm classification procedures, after debugging, useful for beginners)

说明：  计算图像间的互信息量，从而有效衡量图像间的相关程度。(mutual information of image)

this program simulate tarcking algorithm based on wavelet.
