Multistage Relaying Using Interference Networks
Wireless networks with multiple nodes that relay information from a source to a destination are expected to be deployed in many applications. In this work, we consider multihoppin...

Joint Precoding for MIMO-Relay Systems with Partial Channel State Information
—In this paper, we propose a joint precoding scheme for both the base station (BS) and relay station (RS) to increase the ergodic capacity of downlink non-regenerative multiple-i...

Cooperation with an untrusted relay: a secrecy perspective
We consider the communication scenario where a source-destination pair wishes to keep the information secret from a relay node despite wanting to enlist its help. For this scenario...

Multiple-antenna multiple-relay system with precoding for multiuser transmission
Multi-hop relaying will play a central role in next generation wireless systems. In this paper a novel relaying strategy that uses multiple-input multiple-output (MIMO) relays in ...

Cooperative communications with relay-selection: when to cooperate and whom to cooperate with?
Abstract--In this paper, we propose a new cooperative communication protocol, which achieves higher bandwidth efficiency while guaranteeing the same diversity order as that of the ...
