ABSTRACT: In this paper we analyze the performance of two-way interference-limited amplify-and-forward relaying systems over independent non-identically distributed Nakagami-m fading channels. The lower bounds of the outage probability and symbol error probability are obtained. By using the derived lower bounds, three optimization problems namely, power allocation under fixed location for the relay, optimal relay position with fixed power allocation and joint optimization of power allocation and relay position were solved, for the case of Rayleigh fading. We proposed a method for compensating the effect of Carrier Frequency Offset on the system performance of amplify-and-forward relays.
