Power Allocation for Two-Way Opportunistic Amplify-and-Forward Relaying over Nakagami-m Channels

Abstract: We are concerned with transmit power optimization for two-way opportunistic relaying (TWOR) systems in amplifyand-forward (AF) strategy over independent and non-identically distributed (i.ni.d.) Nakagami-m fading channels. With instantaneous squared channel strength known to source nodes before transmitting, we derive an optimum power allocation (OPA) scheme by solving an optimization problem of signal-to-noise ratio (SNR) balancing. While with only statistical channel knowledge, we propose a sub-OPA scheme th… Show more

“…When the total sum of transmission powers at the SUS and SUR is constrained, the outage probability is consequently minimized when the SINRs at SUR and SUD are identical, i.e., γR = γD [9]. Thus, in order to minimize the outage probability, the transmission powers of the SUS and SUR are satisfied as follows:…”
