Coding theory in white Gaussian channel with feedback

Journal of Multivariate Analysis, 1974, vol. 4, issue 1, 74-87

Abstract: The message m = {m(t)} is a Gaussian process that is to be transmitted through the white Gaussian channel with feedback: . Under the average power constraint, , we construct causally the optimal coding, in the sense that the mutual information It(m, Y) between the message m and the channel output Y (up to t) is maximized. The optimal coding is presented by , where and A(s) is a positive function such that .
