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 known as multi-path transmission signals. This procedure is carried out on the wireless channel simulation.
