Description
Summary:In this letter, under the assumption of multiple antennas are available at the relay nodes, we provide a detailed analysis about the performance of opportunistic multi-antenna relay selection (OMRS) scheme in Decode-and-Forward (DF) relay networks over independent, non-identical, Nakagami-m fading channels. By applying the moment-generating function (MGF) of the total signal-to-noise ratio (SNR) at the destination, the closed-form expressions of outage probability and error performance for binary phase shift keying (BPSK) modulation of OMRS scheme are derived. Simulations results show fine consistency with theoretical analysis.
