On The Performance of MIMO AF Full-Duplex Joint Antenna and Relay Selection Network

This paper investigates a multi-input multi-output (MIMO) multi-relay amplify-and-forward (AF) full-duplex (FD) network using optimal joint relay and antenna selection over Rayleigh block fading channels. For system performance analysis, outage probability (OP) is theoretically analyzed to obtain exact and asymptotic expressions of OP where asymptotic derivations using the assumption of high signal-to-noise rate (SNR) regime. Numerical results are provided to verify the validity of the derived OP expressions by comparing with the related empirical performance. The paper shows that under different scenarios the exact OP expression values are close the related empirical ones while the approximated OP expression values approach to the empirical OP under high SNR conditions.
