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 …

Jul 1, 2024 · From Steven M. Kay's book fundamentals of statistical signal processing, he derives in chapter 3 the CRLB for a single sinusoidal frequency estimation in WGN when the amplitude and …
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.
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 …
What can we deduce about variance when we are given the noise …
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 ...
