Outage optimality of amplify-and-forward opportunistic relayingOutage optimality of amplify-and-forward opportunistic relaying Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-262007enIn this paper, we show that optimal selection and transmission of a single relay among a set of multiple amplify-and-forward (AF) candidates minimize the outage probability (i.e., outage-optimal) and outperform any other strategy that involves simultaneous transmissions from more than one AF relay under an aggregate power constraint. This outage optimality demonstrates that cooperation benefits are maximized with intelligent scheduling among AF relays.http://creativecommons.org/licenses/by/4.0/IEEE Communications Letters113261 - 263 Bletsas Aggelos Μπλετσας Αγγελος Win, M.Z.
