Cooperative Space-Time Coded Transmissions in Nakagami-m Fading Channels
— In this paper we evaluate outage performance of a cooperative transmission protocol over fading channels that requires a number of relaying nodes to employ a distributed space-...

On the delay and throughput of digital and analog network coding for wireless broadcast
— We address the problem of exchanging broadcast packets among multiple wireless terminals through a single relay node. The objective is to evaluate the delay and throughput gain...

On channel estimation and optimal training design for amplify and forward relay networks
In this paper, we provide a complete study on the training based channel estimation issues for relay networks that employ the amplify-and-forward (AF) transmission scheme. We first...

Lossy Source Transmission over the Relay Channel
Lossy transmission over a relay channel in which the relay has access to correlated side information is considered. First, a joint source-channel decode-and-forward scheme is propo...

Asymptotically optimal cooperative wireless networks with reduced signaling complexity
Abstract— This paper considers an orthogonal amplify-andforward (OAF) protocol for cooperative relay communication over Rayleigh-fading channels in which the intermediate relays ...
