fft 快速傅立叶变换，可以进行有效的变换，用于频谱和功率普的分析。(fft)

说明：  继续上次传的简单遗传算法，本次加入啦总体部分。(Continue to the last mass of the simple genetic algorithm, this time adding a whole part of you.)

本书对无线信道的建模、OFDM以及MIMO的基础理论和实践作了一个综合的介绍，并给出了MIMO-OFDM系统基本的的技术matlab仿真代码，非常值得从事无线通信系统研究仿真人员作为参考。(MIMO-OFDM is a key technology for next-generation cellular communications (3GPP-LTE, Mobile WiMAX, IMT-Advanced) as well as wireless LAN (IEEE 802.11a, IEEE 802.11n), wireless PAN (MB-OFDM), and broadcasting (DAB, DVB, DMB). This book provides a comprehensive introduction to the basic theory and practice of wireless channel modeling, OFDM, and MIMO, with MATLAB programs to simulate the underlying techniques on MIMO-OFDM systems.)

说明：  此程序用来瑞利衰落信道仿真,用于无线环境，希望能有所帮助(This procedure used to Rayleigh fading channel simulation, used in wireless environment, hoping to be helpful)
