摘要：
In this paper, we analyze performance of a full-duplex (FD) decode-and-forward (DF) two-way relay system, where two terminal nodes exchange information via a relay node over a same frequency band and time slot. Unlike previous works on two-way full-duplex relay systems, we consider a system which is affected by both hardware impairments and residual interference due to imperfect self-interference cancellation (SIC) at the full-duplex nodes. We derive exact outage probability based on the signal to interference plus noise and distortion ratio of the considered system. Our analysis based on numerical results show significant performance degradation due to transceiver impairments. The outage probability is caused to fall to an irreducible floor even at low residual self-interference. Finally, Monte Carlo simulations are also used to validate numerical results.
