MATLAB: Complex Gaussian noise signals with zero mean and different variance

complexvariance

Hi;
 I need to generate in matlab  complex Gaussian noise signals with zero mean and different typical values of variance  .

Best Answer

Assuming your signals are not correlated, you could do it with
cgnoise = std1*randn(n,1) + i*std2*randn(n,1);
where std1 and std2 are the standard deviations.
