一个很好用的matlab视频跟踪程序，里面有对应的视频文件，直接就可以仿真运行，方便大家学习。(A good use of matlab video tracking program, which has a corresponding video file, you can directly run the simulation to facilitate learning.)

zoomfft matlab代码，需要改(zoomfft matlab code, need to change)

是基于STBC的MIMO-OFDM的MATLAB仿真，生成误码率曲线(MATLAB simulation is based on the STBC MIMO-OFDM generate BER curves)

QPSK 仿真 根据原理给出QPSK调制以及解调的SIMULINK仿真图（已调信号波形，解调后的信号波形，眼图和误码率图） 用MATLAB语言实现QPSK调制和解调，给出信号的波形，眼图及误码率等。 (qpsk)

matlab程序设计之环境变量教程environmental variables matlab programming tutorial(environmental variables matlab programming tutorials environmental variables matlab programming tutorial)

this is solve for PDE equation. using the backward difference method.

说明：  matlab 系统仿真 实例第十二章所有例子，可以学习下；(matlab simulation examples of Chapter XII of all the examples, you can learn from the next )

本压缩包提供了本人课程教学期间课堂演示的PCM编码与解码、2FSK、2ASK、2PSK调制、基带升弦系统。每个模块达到参数都作了优化，以求获得良好的演示效果，对于学习通信原理课程、本科课程或毕业设计同学非常有用。(The folder include the code for PCM ,2ASK,2PSK,2FSK, base-band raised cosine System. All this was did in the matlab7.0/simulink 。 the parameters in every module prefer in order to get the excellent result .the folder is very useful for students in learning the communication theory and simulink .especially for lesson tasks .)
