Performance analysis of full duplex relaying in multicell environment

This paper analyzes the performance of the full duplex relaying (FDR) based cooperative communication system in a multi-cell environment. In multi-cell environment the FDR is prone to co-channel interferers due to higher reuse of the frequency. Owing to the possibility of imperfect mitigation at the relay we, in this paper, model the self-interference (or echo-interference) channel, which exists between the transmitting and the receiving antennas of the relay, as a fading channel with Nakagami-m fading distribution. For the decode and forward (DF) relay, we analyze the error performance and derive an exact closed form expression of the average bit error rate (BER). Further, an exact closed form expression for outage probability of the considered system is also obtained.
