wgn cancels outsiders next tv represents a topic that has garnered significant attention and interest. generating white gaussian noise in matlab using two different functions. I want to know the difference between the two Gaussian noises generated below? Which one is white and how can i make the other one white? y=wgn(1,10000,0) and y=randn(1,10000); How to calculate SNR with White gaussian noise.
Im working on a Pulsed Doppler Radar What is the way to calculate the SNR (with WGN)? This perspective suggests that, what will be the lowest SNR for detectability? Im using matched-filter(xcorr) to process the signal+noise. How to add white gaussian noise to an image in Matlab?.
use y=wgn (m,n,p) command in matlab. it generates a mxn matrix of white Gaussian noise. p specifies the power of y in decibels relative to a watt. Variance of White Gaussian Noise - Signal Processing Stack Exchange. It could seem an easy question and without any doubts it is but I'm trying to calculate the variance of white Gaussian noise without any result.
The power spectral density (PSD) of additive white Gaussian signal generation - Signal Processing Stack Exchange. This perspective suggests that, edit: Could the following be the answer?
Generate WGN-like-signal which is centered around a set dBm value. Treat that signal like it was a frequency domain representation of an unknown X time-domain How to Generate White Gaussian Noise with Known PSD in MATLAB.
Using wgn I can generate noise with specific power (dBW) but I want to generate a white noise with constant or know PSD. Can anyone give me ...

$\sigma^2 \delta [k]$ is the auto-correlation sequence of WGN process. Similarly, and, PSD of WGN process is DTFT of the Auto-correlation sequence which will be $\sigma^2$. This perspective suggests that, matlab: White noise with flat/constant power spectrum.
I am relatively new to signal processing techniques and Matlab and need a bunch of test data in the form of white noise, as defined on the Wikipedia page, with constant, flat power spectrum.
