We investigate the optimal power and rate allocation for multilayer transmission using the broadcast approach over a fading amplify-and-forward relay channel. The source uses multilayer source coding with successive refinement where the layers are transmitted using superposition coding at the source with optimal rate and power allocation. The destination applies successive interference cancellation...
In this paper, we consider a fading relay channel where the source uses multilayer source coding with successive refinement. The source layers are transmitted using superposition coding at the source with optimal power allocation. The relay uses the simple half-duplex amplify-and-forward strategy. The destination applies successive interference cancellation after optimally combining the direct and...
In this paper, we consider a fading relay channel where the source uses two layers source coding with successive refinement. The two source layers are transmitted using superposition coding at the source and relay with optimal power allocation, and successive interference cancellation at the receivers (i.e. relay and destination). The power allocation for the two layers at the source and relay is...
