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)?
Understanding the Context
What will be the lowest SNR for detectability? Im using matched-filter(xcorr) to process the. 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. Aug 20, 2018 · I want to generate white Gaussian noise with known PSD. Using wgn I can generate noise with specific power (dBW) but I want to generate a white noise with constant or know PSD.. Mar 31, 2020 · Edit: Could the following be the answer? Generate WGN-like-signal which is centered around a set dBm value.
Final Thoughts
Treat that signal like it was a frequency domain representation of an. @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 $\sigma^2$. Jan 17, 2018 · Am studying unbiased estimators and keep seeing this term "DC Level". What is the expansion of DC and what is a DC Level?
Even the Wikipedia page on WGN says nothing about it.
