© 2015 IEEE. In this paper, we propose a full-duplex physical-layer network coding (FD-PLNC) scheme for reciprocal asymmetric frequency-selective multipath channels using orthogonal frequency-division multiplexing (OFDM) and denoise and forward (DNF) relaying. We consider a network scenario of two-way relay channels (FD-TWRCS) with two source nodes, A and B, intending to exchange information with the aid of a relay node R. All nodes operate in full-duplex mode and are equipped with two antennas dedicated for transmission and reception, respectively. Moreover, the proposed FD-PLNC system is combined with an active self-interference cancellation scheme in order to minimize the effect of self-interference and its performance is investigated in the presence of channel estimation errors. Semi-analytical bit error rate performance (BER) expressions as a function of the signal to noise ratio (SNR) are derived to describe the end-to-end performance. Simulation based performance results show a close match with the derived semi-analytical solutions demonstrating the feasibility of FD-PLNC using the active self-interference cancellation scheme. Furthermore, it is demonstrated that the proposed FD-PLNC scheme can increase the throughput of the conventional TWRC network by a factor of 4 and the throughput of the half-duplex physical-layer network coding (HD-PLNC) by a factor of 2.
