Optimality of FDMA in Gaussian Multiple-Access Channels with Non-zero SNR Margin and Gap
— This paper investigates the effect of non-zero SNR margin and coding gap on the maximum sum rate and achievable rate region of the Gaussian Multiple-Access Channel (MAC). Frequ...

An Asymptotically Sum-Rate Optimal Precoding Scheme for MIMO Gaussian Broadcast Channel
—In this paper, we study the downlink precoding schemes for MIMO Gaussian broadcast channels (MIMO GBC). A novel low-complexity zero-forcing dirty-paper-coding (DPC) scheme, name...

Resource Allocation for Wireless Fading Relay Channels: Max-Min Solution
—Resource allocation is investigated for fading relay channels under separate power constraints at the source and relay nodes. As a basic information-theoretic model for fading r...

Secure Degrees of Freedom for Gaussian Channels with Interference: Structured Codes Outperform Gaussian Signaling
—In this work, we prove that a positive secure degree of freedom is achievable for a large class of real Gaussian channels as long as the channel is not degraded and the channel ...

A New Sum-Rate Outer Bound for Interference Channels with Three Source-Destination Pairs
—This paper derives a novel sum-rate outer bound for the general memoryless interference channel with three users. The derivation is a generalization of the techniques developed ...
