Performance Analysis of Multiple Antenna Two-Way Relaying over Nakagami-m Fading Channel

In this paper, the end-to-end signal noise ratio (SNR) expression is derived in the multiple antenna two-way amplify-and-forward (AF) relay system using beamforming over non-identically distributed independent Nakagami-m channels. The cumulative distribution function and the probability density function of end-to-end SNR are deduced. Utilizing the accumulative distribution function, the closed expressions of outage probability and average symbol error ratio are derived. The simulation results demonstrate the validity of the theoretical analysis.
