说明：  matlab的入门学习好帮手，我看了后学到了很多，希望和大家共享。(Matlab to learn good helper, I watched a lot of deconstruction, hoped and everybody sharing.)

roc 曲线的画法源代码 方便广大初学者应用(PLOTROC Plot receiver operating characteristic)

一个PSO算法历程，有详细的注释，及相关演示过程。采用了基本PSO、权重优化、最大速度法三种（去掉代码中的相关行的注释即可使用）。(PSO algorithm is a process, detailed notes, and related presentation process. With the basic PSO, weight optimization, the maximum speed law of three (remove the code related to the comment line can be used).)

对原始信号进行四相相移键控调制，然后加入高斯白噪声，对加噪信号进行解调，对比解调信号与原始信号，计算误码率(The original signal quadrature phase shift keying modulation, and then adding Gaussian white noise, plus noise signal is demodulated, comparing the demodulated signal with the original signal, bit error rate calculation)
