Performance of joint relay and antenna selection in the Full-Duplex Amplify-and-Forward relay networks

In this work, joint relay and antenna selection (JRAS) problem in Full-Duplex (FD) Amplify-and-Forward (AF) relaying network is examined. A dual-hop relay system with one source, one destination and N FD AF relays is considered. Each FD relay is equipped with N_r antennas for receiving and N_t antennas for transmitting. In this FD relay system, joint selection strategy involves choosing the best single relay and the best single receive/transmit antenna at the source-to-relay/relay-to-destination links. The system model is developped and the outage probability (OP) and the bit error rate (BER) of the system for different numbers of relay and antenna cases are examined in Rayleigh fading channel via Monte Carlo simulations.
