Side-information Scalable Source Coding
Abstract—We consider the problem of side-information scalable (SI-scalable) source coding, where the encoder constructs a two-layer description, such that the receiver with high ...

Gaussian Interference Channel Capacity to Within One Bit
—The capacity of the two-user Gaussian interference channel has been open for 30 years. The understanding on this problem has been limited. The best known achievable region is du...

Multiple Access Channels with State Information Known at Some Encoders
We consider a multiple access channel (MAC) with channel state information (CSI) non-causally known at some encoders. For simplicity of exposition, we focus on a two-encoder model...

Rate Regions for Relay Broadcast Channels
A partially cooperative relay broadcast channel (RBC) is a three-node network with one source node and two destination nodes (destinations 1 and 2) where destination 1 can act as a...

An outer bound to the capacity region of the broadcast channel
An outer bound to the capacity region of the two-receiver discrete memoryless broadcast channel is given. The outer bound is tight for all cases where the capacity region is known....

On the inner and outer bounds for 2-receiver discrete memoryless broadcast channels
We study the best known general inner bound[1] and outer bound[2] for the capacity region of the two user discrete memory less channel. We prove that a seemingly stronger outer bou...

Capacity Bounds for the Gaussian Interference Channel
Abstract-- The capacity region of the two-user Gaussian Interference Channel (IC) is studied. Two classes of channels are considered: weak and mixed Gaussian IC. For the weak Gauss...

Generalized Secure Distributed Source Coding with Side Information
In this paper, new inner and outer bounds on the achievable compression-equivocation rate region for generalized secure data compression with side information are given that do not...

New Outer Bounds on the Marginal Polytope
We give a new class of outer bounds on the marginal polytope, and propose a cutting-plane algorithm for efficiently optimizing over these constraints. When combined with a concav...

The Relay Channel with a Wire-tapper
— In this work a relay channel with a wire-tapper is studied for both discrete memoryless and Gaussian channels. The wire-tapper receives a physically degraded version of the des...
