Abstract

In this paper, under Rayleigh fading environment, we focus on the relay selection problem in the multiple full-duplex (FD) relay networks consisting of one source, one destination, and N FD decode-and-forward (DF) relays. The optimal relay selection that requires global channel state information (CSI) and three suboptimal relay selection schemes that utilize partial CSI are discussed over independent- and identically- distributed (I.I.D.) Rayleigh fading channels. Moreover, to facilitate analysis, outage probability expressions of these schemes are derived. Then, Comparing DF protocol with amplify-to-forward protocol (AF), numerical results show that DF-relay can achieve a better performance. Besides, the effects of self-interference-to-noise ratio (INR) and the number of relay on outage probability for different selection schemes are investigated. Correspondingly, the best suboptimal scheme and relay arrangement policy have been obtained. Finally, Monte-Carlo simulations are performed to demonstrate the validity of the analytical results.
