Abstract: In this paper, we investigate the performance of multiple antenna two-way relay network with transmit beamforming and maximum ratio combining, in the presence of multiple interferers and noise over Nakagami-m fading channels. We have evaluated the signal-to-interference-plus-noise ratio (SINR) in closed-form, along with the tight lower bound on the outage probability (OP). The average symbol error probability (SEP) for binary phase shift keying is evaluated by using cumulative distribution function of the SINR. Furthermore, to render insights into the performance degradation due to the effect of interference, asymptotic expression of OP and SEP are obtained, which easily enables us to evaluate diversity order and coding gain. We further investigate the joint optimization problem of relay location and power allocation to minimize the OP. Finally, the tightness of our analysis is attested through Monte Carlo simulation.
