Electrical and Computer Engineering ETDs
This paper is concerned with the problem of obtaining the optimal linear vector coding (transformation) method that matches an r-dimensional vector signal and a k-dimensional channel under a given channel power constraint. the encoder converts the r correlated random variables into r independent random variables and selects at most k independent random variables which correspond to the k largest eigenvalues of the signal covarience matrix Q. The encoder reinserts cross-correlation into the k random variables in such a way that the largest eigenvalue of Q is assigned to the smallest eigenvalue of the channel noise covarience matrix R and the …
