瑞丽信道仿真 噪声信号由MATLAB函数randn(1,N)产生，它从均值为0、方差为1的正态分布中产生N个伪随机数。每次迭代时，要使用相应的标准差对噪声的幅度进行尺度变换，最后，将输入信号和噪声信号相加得到输出信号。-Ruili channel simulation noise signal by the MATLAB function randn (1, N) generated, which from the mean 0, variance for a normal distribution N generate a pseudo-random numbers. Each iteration, it is necessary to use the corresponding standard deviation of the noise amplitude scaling, finally, the input signal and the noise signal to be added to the output signal.
