We show that the duality between channel capacity and data compression is retained when state information is available to the sender, to the receiver, to both, or to neither. We pr...
This paper considers the problem of estimating the parameters of real-valued two-dimensional (2-D) sinusoidal signals observed in colored noise. This problem is a special case of t...
This paper provides a mathematical analysis of transform compression in its relationship to linear and nonlinear approximation theory. Contrasting linear and nonlinear approximatio...

Previous studies have shown that single-user systems employing -element antenna arrays at both the transmitter and the receiver can achieve a capacity proportional to , assuming in...

Abstract-- In this paper, a necessary and sufficient condition for sampling in the general framework of shift invariant spaces is derived. Then this result is applied respectively ...
Abstract--In this paper, we establish a one-to-one correspondence between information inequalities and group inequalities. The major implication of our result is that we can prove ...
