OFDM为正交频分复用，频谱利用率高，抗干扰性强，应用前景广泛，为4G发展的核心技术，本文用matlan对其进行仿真-OFDM orthogonal frequency division multiplexing, high spectrum efficiency, interference is strong, broad application prospects, 4G development of the core technology, matlan its simulation

本程序实现了基于相关矩阵法的LTE及4G中MIMO多径信道的仿真，最终获得了MIMO信道的传播矩阵。（第一步，选择应用场景（确定信道参数和天线配置参数）；第二步，计算相关矩阵，并做Cholesky分解；第三步,利用Jakes模型产生多普勒随机变量；第四步,形成TDL；第五步，根据前四步准备，最终得到MIMO多径信道的信道传输矩阵）-This procedure achieved based on the correlation matrix method and 4 g LTE MIMO in

对4G中不同信道的速率匹配的仿真 对4G中的不同信道都可使用，，，用处很广-The rate of 4G different channels matched simulation 4G different channels can be used ,,, wide use
