Outage performance for interference-limited decode-and-forward two-way relaying networks

In this paper, the outage performance for a decode-and-forward two-way relay network is investigated in the presence of multiple interferers at the source terminals. The exact expression for the outage probability is derived and the disparity is discussed between symmetrical and asymmetrical cases. Based on the closed-form expressions the optimal power allocation between source terminals is discussed and the diversity order is derived. The effect of interference power is also studied. Simulation results are provided to validate the analytical results.
