Diversity-Multiplexing Tradeoff in Half-Duplex Relay Systems
— We study the multiple antenna half-duplex relay channel from the diversity-multiplexing tradeoff (DMT) perspective. We find performance upper bounds and show that compress-and...

Partial Decoding for Synchronous and Asynchronous Gaussian Multiple Relay Channels
— Relaying diversity is a key technology to increase capacity in wireless networks. In this paper, the capacity of a single source-destination wireless channel, aided by a set of...

Two-relay distributed switch and stay combining
We study a distributed version of switch-and-stay combining (DSSC) for systems that utilize two relays. In particular, four different scenarios are considered, depending on a) whet...

Relay Selection in Multi-Node Cooperative Communications: When to Cooperate and Whom to Cooperate with?
Abstract— In this paper, we propose a new cooperative communication protocol, which achieves high bandwidth efficiency while guaranteeing full diversity order. The proposed sche...

Diversity-Multiplexing Tradeoff of the Half-Duplex Relay Channel
We show that the diversity-multiplexing tradeoff of a half-duplex single-relay channel with identically distributed Rayleigh fading channel gains meets the 2 by 1 MISO bound. We ge...
