Optimal and low-complexity iterative joint network/channel decoding for the multiple-access relay channel
In this paper, we investigate joint network and channel decoding algorithms for the multiple-access relay channel. We consider a realistic reference scenario with Rayleigh fading ...

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...

Two-relay distributed switch and stay combining
We study a distributed version of switch-and-stay combining (DSSC) for systems that utilize two relays. In particular, four different scenarios are considered, depending on a) whet...
