在这个例子中，我们对有三条固定路径的AWGN多径信道中的QPSK系统进行BER性能仿真，并与在理想的AWGN信道（没有多径）中同样系统的BER性能进行比较。(In this example, we have three fixed-path multipath AWGN channel QPSK system BER performance simulation, and in an ideal AWGN channel (no multipath) in the same system BER performance comparison Progressive line.)

待辨识对象参数a=[1 -1.5 0.7] b=[1 0.5] 输入采用长度L=400的白噪声序列，输出 ，输入和输出数据均含不相关随机噪声，ρ（k）=1/k。利用上述递推公式，辨识系统参数。(To identify the object parameters a = [1-1.5 0.7] B = [1 0.5] Input the length L = 400 white noise sequence, the output, the input and output data are not related with random noise, ρ (k) = 1/k. Using the recursion formula, identification system parameters.)
