Description: 如何在图像中加入某一固定snr的噪声？分类:matlab与图像处理
在利用matlab做一些自己算法的抗噪分析中，常常会遇到这个问题，matlab中的加噪函数是imnoise，里面的参数是噪声的均值，方差（高斯噪声）或者是感染概率（椒盐噪声），参数不能是snr值，但是很多国外的文章的噪声分析中都是用snr值来衡量加入噪声的程度的-how the image to a fixed snr noise? Categories : Matlab and image processing using Matlab to do some of his own anti-noise algorithm analysis, will often encounter this problem, which Matlab the noise function is imnoise. inside the parameters of the noise mean and variance (Gaussian noise) or the probability of infection (Impulse Noise) Parameter values can not be snr, But many foreign article noise analysis is used to measure the value snr joined the extent of noise

Description: 很好的OFDM的基于MATLAB的仿真程序包，且包含了最终结果图.-montecarlo
type montecarlo in the command window and wait for a long time..
_simulation of the complete OFDM system.
_use of a very large file in order to get probabilities.
_loop over different value of the noise.
_compute the SNR for each value of the noise.
_provide the SNR/BER plot.
if you are in a rush : simulation_system !!
go into the right folder and type simulation_system in the command window.
_then type the value of the noise power (range = [-20,10])
_the function provides the channel estimation, the bit allocation,
and a plot illustrating the errors.
_this is a fast function (less pilot, no synchronization, small file).
