Duality between channel capacity and rate distortion with two-sided state information
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...

Least squares estimation of 2-D sinusoids in colored noise: Asymptotic analysis
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...

Capacity scaling in MIMO Wireless systems under correlated fading
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...

On a relation between information inequalities and group theory
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 ...
