说明：  OFDM系统功能仿真，很好很强大，嗯嗯嗯(OFDM system, functional simulation, very good very strong, er er er)

其中包含了三种算法，粒子群优化方法，遗传算法和蚁群算法(Which contains the three algorithms, particle swarm optimization, genetic algorithms and ant colony algorithm)

PAPR reduction coding in MATLAB

应用FFT方法计算时间序列平均周期的源码。不是很复杂，不过效果比较好。可供参考(Application of FFT calculated the average cycle time of the source sequence. Not very complicated, but the effect is better. For reference)

说明：  最基本的matlab函数，最全面，最基础，希望能有用(Matlab basic functions, the most comprehensive, the most basic and hope to be useful)

this is an optimization matlab code based on a simulated annealing method
