Abstract
In this paper we investigate the performance of an amplify-and-forward multi-input multi-output two way relay network where two sources are equipped with multiple antennas employing maximal ratio transmission and the communication is carried through the selected relay resulting in the largest received power. Assuming the fading channel coefficients are Nakagami-m distributed we derive the sum symbol error rate (SSER) outage probabilities for each user and the overall system. In addition diversity and array gains are obtained using the derived asymptotic SSER and system outage probability (OP) expressions. With the help of asymptotic system OP we find the optimum location of relay by solving the convex optimization problem. Furthermore we investigate the impact of limited feedback and imperfect channel estimations on the performance of the proposed structure. Finally theoretical findings are validated by simulation results.
