Outage probability of two-way amplify-and-forward relaying system with interference-limited relay

In the paper, we investigate the overall outage probability (OOP) 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 OOP are derived. In addition, it is shown that, in terms of the outage probability performance, the worst scenario appears to be the case with equal received-power interferers, for a given total received interference power in this system model. The analysis results are verified through comparison with the simulation results.
