| Abstract: | In this paper, the outage performance of opportunistic relay (OR) and equal gain transmission-beamforming (EGT-BF) are studied in decode-and-forward (DF) relay networks over Nakagami-m fading channels, assuming multiple relays are available in the networks. We derive the moment generation function (MGF) of the signal-to-noise ratio (SNR) at the destination, then obtain the exact closed-form solution of OR and the approximate closed form expression of EGT-BF |
