In this paper, the authors compare Full-Duplex (FD) and Half-Duplex (HD) relaying in terms of outage probability and throughput. They consider a practical FD relay model where the loop interference between transmitted and received signals is taken into account. They analyze two modes for FD transmission, block Markov encoding and multi-hop transmission without interference cancellation, and two different modes for HD transmission, which are based on selective and incremental decode-and-forward protocols. Results show that there is a tradeoff between SNR and information rate in which each scheme becomes more suitable.
