Circular gaussian complex random variable

WebDec 30, 2024 · One of the properties of circular symmetric complex Gaussian vectors is that the pseudo-covariance matrix is all zeros. For the scalar case, this implies that the real and imaginary parts are independent and have the same variance. WebAug 31, 2024 · It's the transformation of Gaussian random variables. If you square a sequence of Gaussian random variables and sum them you get a Chi squared random variable. Further, taking the square root gives another distribution. The signal portion transforms that way.
