摘要：

This paper presents the performance analysis of two-time-slot two-way relaying while considering dual antennas at the relay and imperfect channel state information (CSI) at the receivers. We consider the Max-Min antenna selection scheme at the relay. For this scheme, we show the analytical symbol error probability in the presence of imperfect CSI and observe a close match between the analytical and numerical results. We also find that Max-Min antenna selection scheme is robust against CSI error and performs better than the maximum ratio transmission (MRT) based beamforming scheme in the presence of CSI error.
