swarm algorithm optimization

基于平方包络的PSK 信号的码元速率估计。(Symbol rate is estimated based on square envelope QPSK signal. mpsk function and test_signal in cwt compressed package.)

给Matlab配套的电力工具箱POWERSYSTEM的最全的使用手册，一共一千多页，POWERSYSTEM中所有的DEMO都有详细介绍，是学习电力工具箱的精品资料(Matching of electricity to Matlab toolbox POWERSYSTEM the most comprehensive user manual, a total of more than 1000 pages, POWERSYSTEM have all the details of DEMO is to learn the power of quality information toolbox)

说明：  dsc单边带调制。功能是用10Hz的载波信号去调制频率为500Hz的基带信号，然后得到单边带调制信号(single-sideband modulation)

Particle swarm optimization code

关于matlab机器人工具箱的使用，为更好的使用matlab的仿真功能(this is about matlab robotics toolbox)

This source code give the explanation about generate QPSK simulation

在不同信噪比条件下，对于不同调制方式所产生的误码率曲线！(Signal to noise ratio in different conditions, for different modulation generated BER curves!)

用程序写的按钮之类的，我也没搞懂，不是直接添加GUI按钮(oh,it is a )
