simulation OFDM by matlab 6.5.It s any bug

bp for matlab and can be train each oder

LSB方法隐写图像,空域处理，基于修改图像LSB层的数据，达到隐藏秘密信息的目的(steganografic by LSB)

说明：  动态聚类的k均值算法－－用k均值算法解决动态聚类问题(Dynamic clustering k-means algorithm- using k-means algorithm to solve the issue of dynamic clustering)

pcm编码设计和最佳量化器设计仿真程序。建议在matlab 6.1 或以上的版本，可直接运行。(pcm coding design and the best quantitative design simulation program. Recommendations in Matlab 6.1 or more versions can run.)

QAM编码调制 通信系统中常用的调制方式(QAM )

说明：  基于matlab的动态规划！非常好用！但运行比较麻烦(Matlab-based dynamic programming! Very easy to use! But running is too much trouble)

非平稳信号的瞬时频率、群延时、信号生成方法(Sub-stationary signal the instantaneous frequency, group delay, Signal Generation)

本程序采用遗传算法接力进化,子函数和主函数不要放在一起，子函数另外作为一个M文件，运行主函数。多次运行主函数，直到达到误差满意的效果。(This procedure using genetic algorithm (ga) relay evolution, function and main function don t together, and function of the file as a M, run the main function. Run several times the main function, the error until you reach satisfactory results. )

一个emd分解的matlab实现，可以用的，已经验证过了呀！(EMD decomposition of a realization of matlab, you can use, it has already been verified!)
