In this paper, the performance of the two-way relaying under the influence of channel estimation error and co-channel interference is analyzed. At the very beginning, based on the expression of the received signal-to-interference-plus-noise ratio (SINR), we work out the cumulative probability distribution function and the exact closed-form and approximate expressions of the outage probability. Then, we further derive the bit error rate (BER) of system. Finally, in order to reduce the impact of channel estimation error and interference on the system, we propose an appropriate power allocation scheme to reach a compromise between the outage probabilities of the two terminals. Our theoretical analysis is justified by the result of numerical simulation.
