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 …

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.

Jun 16, 2018 · Isn't the noise power the variance of the noise voltage? One could also ask about the variance (or standard deviation) of the power measured over a specific time interval. I think …

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 …

@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 $\sigma^2$.

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 …

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. …

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 …

Given the noise spectral density $ {N_0\over 2} = a$, what can be deduced about the variance? In the case of a two-symbol canal (/cable), and when $T_0 = 1$. Is it ...
