The hardware implementation of AWGN accelerates the performance evaluation of wireless communication systems using an AWGN channel. AWGN on MATLAB This repository contains a MATLAB script that generates a white Gaussian noise with a given power spectral density (psd). The script implements the following steps: Given the target PSD, the total noise power is computed. Matlab/Octave communication toolbox has an inbuilt function named - awgn() with which one can add an Additive Gaussian White Noise to obtain the desired Signal to NoiseRatio (SNR). The main usage of this function is to awgnchan = comm.AWGNChannel (Name,Value) creates a AWGN channel object, awgnchan, with the specified property Name set to the specified Value. You can specify additional name-value pair arguments in any order as (Name1, Value1,, NameN, ValueN). Matlab code The following custom function written in Matlab, can be used for adding AWGN noise to an incoming signal.

Start Hunting! Discover Live Editor. noise = sqrt (variance)*randn (size (x)); If you use 'measured', then awgn actually measures the signal power. For example: x = cos (pi/4* (0:99)); y = awgn (x,5,'measured'); In this case the variance of the additive white noise is: sigp = 10*log10 (norm (x,2)^2/numel (x)); snr = sigp-5; noisep = 10^ (snr/10); Matlab函数——awgn.
