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 …

Noise PSD and sampling rate relation - Signal Processing Stack Exchange
@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 $\sigma^2$.
What is DC level in white gaussian noise?
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.
Does PSD (dBm/Hz) of white noise depend on sampling rate?
Apr 24, 2023 · Traditional WGN with a non-zero power spectral density and no-band-limiting has infinite power, and consistent with that is the Dirac delta as its Autocorrelation Function Rxx(τ) R x x (τ), …
How do I add AWGN to an I and Q representation of a signal?
Of course, if you had noise in the signal to begin with and then split it into its I-Q components, each will have noise associated with it. However, OP is talking about simulating it in MATLAB and he has the I …
