Full-duplex denoise-and-forward two-way relaying with DBPSK modulation

摘要

In this paper, we propose a full-duplex denoise-and-forward two-way relaying (FDNF-TWR) scheme with differential binary phase-shift keying (DBPSK) modulation, which do not need instantaneous channel state information. In the proposed scheme, two full-duplex source nodes exchange their information with the help of one full-duplex relay node. A non-coherent relay decoder takes the residual self-interference (RSI) into consideration and maps the received mixed signals into a denoised symbol. A non-coherent source decoder takes the RSI into consideration and obtains the symbol from the relay. The simulation results show that the proposed FDNF-TWR scheme can achieve the bit error rate performance of the half-duplex denoise-and-forward two-way relaying (HDNF-TWR) scheme when the self-interference is cancelled well.
