When I use your suggestion and get a 4 by 4 matrix and then apply the svd, the 'unitary' become more 'unitary'! More detail please help normrnd in MATLAB. The BPSK modulation scheme is used for transmission. The magnitude which has a probability density, is called a Rayleigh random variable. A complex Gaussian vector is circularly symmetric if and only if its mean and pseudocovariance are zero. Since E[eiZ]=eiE[Z], any circularly-symmetric complex random vector must have E[Z]=0,i.e., must have zero mean. The pdf of Z is the the pdf of Z~ = X Y T p(z) = p(~z) = 1 (2)n(det(C ~ Z . stochastic processes: theory for applications pdf Thank you~~, if you have the Image Processing Toolbox you can use, Thank u!
