Özet
Maximum likelihood (ML) detection, link adaptive relaying (LAR) and selection relaying (SR) are among the most popular techniques developed for mitigating error propagation in regenerative decode and forward based cooperative wireless networks. In this paper, three different transmission schemes referred to as hybrid LAR and ML (LAR-ML), hybrid SR and ML (SR-ML) and hybrid SR, LAR and ML (SR-LAR-ML) are introduced to combat the error propagation which are obtained by combining the classical ML, LAR and SR approaches. The performance of the proposed structures are determined by computer simulations and providing a general framework for average BER analysis in case of noncoherent binary frequency shift keying which does not require channel state information at either the users or the destination. It has been shown that all of the proposed techniques supply full diversity gain and prevent performance degradation due to error propagation.
