Superposition coding relaying (SC-relaying) has the merit of high throughput. At the same time, the investigation of diversity-multiplexing tradeoff (DMT) is also particularly useful for the design and analysis of cooperative relaying strategy. In this work, we consider a two-level rate SC-relaying strategy with only destination-to-relay channel state feedback (DR-CSF) under a long term power constraint...
In this work, a novel two-level rate superposition coding relaying (SC-relaying) strategy is investigated. In this SC-relaying strategy, the channel state feedback of relay-to-source is introduced under a long term power constraint at source. For the SC-relaying strategy, the source power SNR exponent constraints are first obtained. And then, by using the power SNR exponent constraints, the optimizing...
