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);
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 signal+noise. My s...

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 phase are known (
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 representation of an unknown X time-domain
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 be the power spectrum.
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 ...

To create Band Limited AWGN all you need is randn in MATLAB. The question lies only in how to set its Standard Deviation. To illustrate that, let's assume our AWGN generator has PSD which equals to $ {N}_ {0} $. Namely we have AWGN with zero mean and variance equals to $ \delta (0) {N}_ {0} $. Assuming we have limited bandwidth channel, hence an ideal LPF is applied. Assume its cutoff ...
