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 therelay’s output only depends on the current received signal at therelay. We propose a novel forwarding strategy for this class of relaychannels which can outperform amplify-and-forward, detectand-forward and estimate-and-forward. The proposed scheme isbased on a remapping of the signal constellation at the relay.
