Robust Cooperative Relaying in a Wireless LAN: Cross-Layer Design and Performance Analysis
—A key technology in cooperative communications is distributed space-time coding (DSTC) which achieves spatial diversity gain from multiple relays. A novel DSTC, called randomize...

Cooperative MIMO-beamforming for multiuser relay networks
In this paper, we develop a beamforming algorithm for multiuser MIMO-relaying wireless systems. We consider a relaying scenario with multiple sources transmitting to one or more d...

Induced Cooperative Multi-user Diversity Relaying for Multi-hop Cellular Networks
— In this paper we study the multi-user diversity gain in the downlink of single-hop and multi-hop infrastructure-based networks. We propose a base-station coordinated cooperativ...
