说明：  用与matlab的fsk调制的信号的波形的代码，可以实现仿真(it is fsk)

matlab说明书，对于matlab编程工作者及其有用，是一本有用的工具书(matlab manuals for workers and their useful matlab programming is a useful tool)

期望最大化算法的ppt，很不错，个人用了，很受益啊。。。(EM algorithm)

matlab各类命令，随取随用，希望有帮助(matlab various commands, acquired and used, hope that helps)

最优化FIR数字带通滤波器的设计，用来对加速度信号进行带通滤波，提取运动信息。(the design of an optimal FIR digital band-pass filter.)

matlab code for Face Detection System

这个是详细的粒子群算法代码。大家可以借鉴参考。(This is the detailed particle swarm optimization code. We can learn from the reference.)

duffing方程相关程序，方程求解，时间历程绘制，相图及庞加莱映射图(duffing, Poincare,phase diagram)

OFDM系统仿真，简单的OFDM基本框架的一个仿真，matlab环境下实现的(it is good！)
