... The advantage of this is that the values of the diagonal matrix D determine the number of independent parallel channels available in the channel H. This is given by the number of non-zero eigenvalues, ... non-zero eigenvalues, each of these gives the rank of that particular sub channel. Also the values obtained from the orthogonal matrices of the SVD gives the gains of the independent channels. ...
