Description: 多径信道仿真
有三条固定路径的AWGN多径信道的QPSK系统进行BER性能方针，并与在理想的AWGN信道中同样系统的BER进行比较，为简化模型，作如下假设：
1，信道中有三条路径，包括一条没有衰落的LOS路径和两条具有瑞利衰落的路径。与各路径相应的接收功率以及路径间的延迟差是仿真的参数
2，信道的锐利衰落仅影响发送信号的幅度，不影响瞬时相位。
3，在符号间隔内各多径分量的衰减幅度是常数，并与相邻间隔无关。-Multipath channel simulation There are three fixed path multipath AWGN channel BER performance of QPSK systems approach, and in an ideal AWGN channel BER the same system for comparison, in order to simplify the model, make the following assumptions: 1, There are three channels path, including a no decline LOS path and the two have a Rayleigh fading path. Corresponding with the path to receive power as well as the path delay difference between the simulation parameters of 2, channel sharp decline affects only the magnitude of the transmitted signal, does not affect the instantaneous phase. 3, in the symbol intervals multipath component of the decay rate is constant, and has nothing to do with the next interval.
