Abstract

In this paper, we compare Full-Duplex (FD) and Half-Duplex (HD) relaying, in terms of outage probability and throughput. We consider a practical relay, where loop inter- ference between transmitted and received signal is taken into account. Two models for FD transmission are considered: Block Markov encoding and multi-hop encoding. For HD transmission, the space-time cooperation is considered. Surprisingly, our results show that HD relaying can outperform FD relaying, specially if loop interference is non negligible. Such results hold even if power and rate allocation are carried out.
