A stochastic control approach to coding with feedback over degraded broadcast channels
In this paper we attempt to further demonstrate connections between information theory and control, in a networked setting. Specifically, we consider the communication problem of b...

A Broadcasting Relay for Orthogonal Multiuser Channels
— This paper introduces broadcasting relay nodes for orthogonal multiuser channels. The underlying idea is that a single relay node is shared by multiple source-destination pairs...

Superimposed XOR: A New Physical Layer Network Coding Scheme for Two-Way Relay Channels
— We present a new physical layer network coding (PLNC) scheme, called superimposed XOR, for two-way relay channels. The new scheme specifically takes into account the channel a...

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...

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...
