Outage performance of partial antenna selection in the full-duplex decode-and-forward relay networks

摘要

In this study, outage probability of partial antenna selection in the full-duplex decode-and-forward multiple-input multiple-output relay networks is investigated over Rayleigh fading channels. In the considered relay network the source, relay and destination are equipped with multiple antennas and it is assumed that direct link is not available due to heavy channel conditions. For signal transmission from the source to destination, while partial antenna selection technique is used in which antennas maximizing the instantaneous signal-to-interference plus noise ratio for the first hop are selected, a single antenna is selected at the destination. End-to-end outage probability expression of the relay network is obtained in closed form and approximated asymptotic expression is also derived. Analytical results are validated by Monte Carlo simulations.
