Rate-Optimized Constellation Rearrangement for the Relay Channel
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 propose...

| description | 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. |
