摘要: Communication schemes exploiting cooperating relay nodes can enable significant SNR and diversity order enhancements. In this paper, a communicating pair of with support from an arbitrary number in parallel is considered, the optimal weighting parameters for coherent combining based non-regenerative relaying are derived under aggregate power constraint. The analysis demonstrates that each merely requires multiplying received signal individual phase amplitude factor common normalization factor. It illustrated resulting substantially enhanced compared to direct communication improves increasing station density.
