自己编写的OFDM发生程序，做仿真的同学可用作源信号，很短，易读，需用matlab工具箱(I have written procedures for OFDM occurred, make simulation the students can be used as a source of signal, very short, easy-to-read, require matlab toolbox)

comparison with the genetic algorithm, the advantages of PSO is simple

说明：  本人提交的用matlab的关于滤波器设计的作业，很有用的　(I used Matlab submitted on the design of filter operation, a very useful)

otsu thresholding method

matlab 版本的LDPC码的译码工具包，很实用(LDPC decoding tollkit of MATLAB Version)

元胞自动机模拟交通流程序，学校交通专业学长给的，能够模拟单车种双车道交通流变化，考虑驾驶员行为。做数学建模美赛的时候用到。(Cellular automaton simulation of traffic flow program, school traffic professional senior, can simulate the change of bike traffic flow, consider driver behavior.)

qpsk通过信道信噪比估计，包括qpsk，8psk，16psk，16qam(qpsk through the channel SNR estimation)

数字信号处理，包括：各种现有信号及随机信号的输入，从文件读取数据的输入，各种滤波器的实现，傅里叶变换等，傅里叶反变换等，谱分析，利用图形界面形式编写，简单且可视化强，便于理解。(Digital Signal Matlab)
