Rate-optimized constellation rearrangement for the relay channel
2008 (English)In: IEEE Communications Letters, ISSN 1089-7798, Vol. 12, no 9, 618-620 p.Article in journal (Refereed) Published
We study the. instantaneous relay channel where the relay's output only depends on the current received signal at the relay. We propose a novel forwarding strategy for this class of relay channels which can outperform amplify-and-forward, detect-and-forward and estimate-and-forward. The proposed scheme is based on a remapping of the signal constellation at the relay.
