Outage, throughput and energy efficiency analysis of some half and full duplex cooperative relaying schemes

Abstract

In this paper, we compare cooperative full-duplex (FD) and incremental cooperative half-duplex (HD) relaying, in terms of outage probability, throughput and energy efficiency. We consider a practical model for the FD relay, where self-interference between transmitted and received signals is taken into account. The FD transmission is based on the well-known block Markov encoding scheme. For the HD transmission, incremental space-time cooperation and selection combining based on the cooperative decode-and-forward protocol are considered. Our results show that incremental cooperative HD relaying can outperform cooperative FD relaying, specially if the self-interference is non-negligible, achieving a better trade-off between throughput and energy consumption.
