An efficient adaptive distributed space time coding scheme for cooperative relaying
A non-regenerative dual-hop wireless system based on distributed Alamouti space-time coding is considered. It is assumed that each relay retransmits an appropriately scaled space-t...

Performance analysis of single relay selection in rayleigh fading
We provide closed-form expressions for the outage and bit error probability (BEP) of uncoded, threshold-based opportunistic relaying (OR) and selection cooperation (SC), at arbitra...

Power Allocation in MMSE Relaying over Frequency-Selective Rayleigh Fading Channels
Abstract--This paper develops an amplify-and-forward relaying scheme for multiuser wireless cooperative networks under frequency-selective block-fading. Single-carrier frequency di...

Resource allocation for cooperative relaying
—The delay-limited capacity of the half-duplex relay channel is analyzed for several cooperative protocols under a long-term average total transmit power constraint. It is assume...

Novel Rateless Coded Selection Cooperation in Dual-Hop Relaying Systems
Selection cooperation is proposed for rateless coded relaying by developing a novel low-complexity protocol that exploits all source-destination, source-relay, and relay-destinatio...
