Outage Performance for Two-Way Relay Channel with Co-Channel Interference

In this paper, the outage performance for amplify-and-forward two-way relay channels is studied in the presence of co-channel interference. We derive the exact outage probability by integral-form expression, and approximate the outage probability with closed-form expression. It is shown by numerical results that the approximations fit well with the exact results in all signal-to-interference plus noise ratio regions, and the approximation perform more exactly when the sum power of interference being large much than the power of noise. Also, the outage performance for different interferers´ power distributions are compared in simulations and it is shown the distribution of interferers´ power has little effect to the outage probability of system.
