On the performance of partial relay selection in dual-hop relaying with beamforming

Abstract

A scheme combining partial relay selection and beamforming in the dual-hop relaying system is proposed. We present the performance analysis of the scheme in Nakagami-m fading by providing closed-form expressions for the outage probability and average bit error probability as well as simple approximations for the two metrics to quantify the performance in high signal-to-noise ratio regime. In the numerical results, the correctness of the theoretical results is validated and the superior performance of the proposed scheme is also shown.
