rayleigh-awgn-BPSK
用rayleighchan 函数仿真时要注意最后要做相位补偿（此问题是导师发现的）
程序步骤：
~产生随机序列
~产生瑞利信道
~调制
~记忆信道特征
~信号通过信道
~相位补偿
~加高斯噪声
~解调
~计算仿真误比特率
~计算理论误比特率
~不同颜色画出误比特率曲线对比(Function Simulation with rayleighchan last thing to note when the phase compensation (this issue is found mentor) program steps: ~ ~ generated random sequence modulation in Rayleigh Road, ~ ~ ~ memory characteristics of the signal channel by channel ~ ~ plus Gaussian noise phase compensation ~ ~ demodulation bit error rate calculation simulation of bit error rate calculation theory ~ ~ different colors to draw curves of bit error rate)
