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
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 …
What can we deduce about variance when we are given the noise …
Given the noise spectral density N0 2 = a N 0 2 = a, what can be deduced about the variance? In the case of a two-symbol canal (/cable), and when T0 = 1 T 0 = 1. Is it that, σ2 X = N0 2 ∗T0 σ X 2 = N 0 …

Matlab: White noise with flat/constant power spectrum
I tried the matlab built-ins wgn(m,n,p) and randn(m,n) to get vectors of white noise, and then used different combinations of the periodogram/pwelch/dspdata.psd functions to check what I believe to …
How to add white gaussian noise to an image in Matlab?
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.
Does PSD (dBm/Hz) of white noise depend on sampling rate?
