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)

说明：通信系统中，信号在传输过程中会叠加上噪声，我们在分析时通常就用高斯白噪声来分析。此程序用来产生高斯白噪声。(communications systems, signal transmission in the process will superimposed on the noise, our analysis is usually used to Gaussian white noise analysis. This procedure used to produce white Gaussian noise.)
