So MATLAB's speckle noise is not laser speckle noise - it uses some SNR in AWGN.

Ha hecho clic en un enlace que corresponde a este comando de MATLAB: I need to create an AWGN, Rayleigh and Rician channel in MATLAB to reduce the transmission power in real time. So that I have to generate a 2*2 and 4*4 channel matrix. For Rayleigh and Rician I created the matrix as shown below. Now please help me to find the channel matrix for AWGN channel. AWGN impairment in MATLAB. This section of MATLAB source code covers AWGN impairment and AWGN effect on constellation diagram using matlab code..
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).

This syntax assumes that the power of in is 0 dBW. example. out = awgn (in,snr,signalpower) accepts an input signal power value in dBW. To have the function measure the power of in before adding noise, specify signalpower as 'measured'.

For the relationships between SNR and other measures of the relative power of the noise, such as E s /N 0, and E b /N 0, see AWGN Channel Noise Level. Modify the AWGN channel object to apply a different Eb/No value to each channel.
