this is a simple2-opt code

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.)

说明：  用matlab实现的bp算法程序用matlab实现的bp算法程序(Bp algorithm using matlab implementation process to achieve the bp algorithm with matlab program)
