基于DFT的MIMO-OFDM系统的信道估计算法研究代码
说明： MIMO系统仿真 ＭＩＭＯ技术可Ｗ极大地提升系统吞吐量和有效抵抗多径衰落的影响，被视作ＬＴＥ的核也技术之一。信号检测模块又是ＭＩＭＯ系统中非常重要的一步，因为接收端收到的信号是经历了无线信道衰落影响的信号，与发送端发送的初始值之间差距较大，因此，在接收端首先应进行信道估计求出信道矩阵Ｈ，然后根据该信道矩阵的信息，从接收端还原出发送信号。因此，在ＭＩＭＯ系统中信号检测直接彰响着系统系能的提升。本章将先介绍高移动性ＭＩＭＯ无线信道的建模方法(simulation of MIMO-OFDM communication system)
