IS95中的数据流伪随机序列的产生。用matlab中randn实现-IS95 data streams to be pseudo-random sequence generation. Achieved using randn in matlab

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

基于IFFT\FFT的OFDM系统仿真。完整的可运行的代码。信源用randn产生，信道为高斯白噪声，如用其他，可以方便自行修改。-Based on IFFT \ FFT of OFDM system simulation. Complete code can be run. Generated using randn source, channel for the Gaussian white noise, such as the use of other, you can easily mod

monte carlo simulation. to run the above simulation input" [y1,y2,y3,y4]= ed(0,1,25,2) " in command window. the "g" in the code above represents the normalisation i.e it represents variance(signal)/variance (noise) as SNR= power(signal)/power(n
