Abstract
In this paper, we investigate end-to-end (e2e) outage probability (OP) performance of dual hop full-duplex (FD) amplify-and-forward (AF) relay network with transmit antenna selection (TAS) and maximal-ratio combining (MRC) over independent identically distributed Rayleigh fading channels. In the network, source and destination are equipped with multiple antennas, and communicate with each other via a single relay, which is equipped with one receive and one transmit antennas. We assume that the direct link between the source and destination is not available. For signal transmission, TAS is used at the source by neglecting residual self-interference (RSI) effect and maximal-ratio combining (MRC) technique is employed at the destination for combining received signals. In order to simplify the theoretical derivations, we also investigate the e2e OP in case that the RSI is non-fading. OP expression is derived in integral form for the Rayleigh faded RSI effect. Moreover, in case of non-fading RSI effect, OP expression is derived in closed form. The analytical results are verified by the Monte Carlo simulations.
