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

C++产生正态分布，泊松分布，瑞利分布的随机数，并画pdf图-The PDFS of Gaussian、Rayleigh and Poisson distributed random variates

随机数的产生，贡献出去，希望大家多多指点。-Random number generation, contribution out hope that many instructions.

产生瑞利分布的随机数,并且通过改变方差的值来改变随机数的图形-Generate a random number of Rayleigh distribution, and by changing the value of the variance to change the random number of graphics

将仿真数据写入TXT文档，是几个函数重载的文件；还有做信道损耗计算的时候需要用到的一些随机数生成函数。(write systemlevel simulation data into txt,in c++,some random number function)
