In this paper,we investigate the performance of the two-way Amplify-and-Forward (AF) relaying systems in an interference-limited Rayleigh fading environment.More specifically,assuming the presence of Rayleigh faded multiple interferers at the AF relay and noisy sources,an approximate closed-form expression for the Overall Outage Probability (OOP) and an integral expression for the average Symbol Error Probability (SEP) are derived.The analysis results are verified through comparison with the Monte Carlo simulation results.
