Writing on Dirty Paper with Resizing and its Application to Quasi-Static Fading Broadcast Channels
— This paper studies a variant of the classical problem of “writing on dirty paper” in which the sum of the input and the interference, or dirt, is multiplied by a random var...

Optimal Coding Strategies for Bidirectional Broadcast Channels Under Channel Uncertainty
Bidirectional relaying is a promising approach to improve the performance in wireless networks such as sensor, ad-hoc, and even cellular systems. Bidirectional relaying applies to...

The pre-log of Gaussian broadcast with feedback can be two
Abstract-- A generic intuition says that the pre-log, or multiplexing gain, cannot be larger than the minimum of the number of transmit and receive dimensions. This suggests that f...

Achievable Rates for the Three User Cooperative Multiple Access Channel
— For a three user Gaussian multiple access channel (MAC), we propose a new superposition block Markov encoding based cooperation scheme. Our scheme allows the three users to sim...

Zero-rate feedback can achieve the empirical capacity
The utility of limited feedback for coding over an individual sequence of DMCs is investigated. This study complements recent results showing how limited or noisy feedback can boos...
