协同网络中继选择算法 一种是基于门限的最大信噪比选择；另一种是基于门限的最小误码率选择，我们将选择一条最佳的中继链路和源节点到目的节点的直接传输链路在目的端进行最大比合并-Research on relay selection algorithm in cooperative wireless Networks

由于无线信道的复杂性，一个通过无线信道传播的信道往往会沿着一些不同的路径到达接收端，这一现象称为信号的多径传输。此程序就是对无线信道进行仿真。-Due to the complexity of wireless channel, a radio channel transmission through the channel tends to follow a number of different paths to reach the receiving end, the phenomenon

matlab环境,瑞利信道下mimo无线通信系统的仿真 不错的-Under the matlab environment, the Rayleigh channel of mimo wireless communication system simulation is good
