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);

Jan 11, 2023 · Im working on a Pulsed Doppler Radar What is the way to calculate the SNR (with WGN)? What will be the lowest SNR for detectability? Im using matched-filter(xcorr) to process the …

Mar 31, 2020 · 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 …

Jun 2, 2015 · 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.

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. I tr...

Apr 11, 2025 · Otherwise, it seems meaningless to talk about "the power" of WGN since the instantaneous power of it is, like it's ground signal, probabilistic. The (statistically) expected value of …

To create Band Limited AWGN all you need is randn in MATLAB. The question lies only in how to set its Standard Deviation. To illustrate that, let's assume our AWGN generator has PSD which equals to $ …

@LewisKelsey Why not? $\sigma^2 \delta [k]$ is the auto-correlation sequence of WGN process. And, PSD of WGN process is DTFT of the Auto-correlation sequence which will be $\sigma^2$.
