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...

A Broadcasting Relay for Orthogonal Multiuser Channels
— This paper introduces broadcasting relay nodes for orthogonal multiuser channels. The underlying idea is that a single relay node is shared by multiple source-destination pairs...

Multi-rate Relaying for Performance Improvement in IEEE 802.11 WLANs
It is well known that the presence of nodes using a low data transmit rate has a disproportionate impact on the performance of an IEEE 802.11 WLAN. ORP is an opportunistic relay pr...

Non-Coherent Detection for Amplify-and-Forward Relay Systems in a Rayleigh Fading Environment
— We consider about a multiple relay system operating under amplify-and-forward (AF) protocol and non-coherent modulation and demodulation. When the relays are under long-term po...

Optimal Distributed Beamforming in Relay Networks with Common Interference
—In wireless relay networks, noise at the relays can be correlated possibly due to common interference or noise propagation from preceding hops. In this work we consider a parall...
