该文件是产生两组随即的高斯分布系列，均值为0，均方差为N/2-The document was then produced two series of Gaussian distribution, the mean of 0 and standard deviation of the N / 2

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 distribu

简单的数据处理包括均值，方差，以及误差数据排除等，使用方便-Simple data processing, including mean, variance, and error data rule out the other, easy to use

此程序用于产生零均值单位方差高斯白噪声的1000个样点，并利用周期图法和平均周期图法进行自相关的估计。(This program is used to produce 1000 sample points under the distribution of zero mean unit variance of Gaussian white noise , and the Periodogram method and average cycle diagram method are used t
