In this paper, the authors consider a practical Orthogonal Frequency Division Multiplexing (OFDM) modulated and Low-Density Parity-Check (LDPC) channel coded two-way relay system employing Physical-Layer Network Coding (PLNC), where two terminals A and B desire to exchange information with each other with the help of a relay R which can be equipped with multiple receive antennas. Orthogonal Frequency Division Multiplexing (OFDM) is adopted as the modulation scheme to resolve the synchronization problem in PLNC and doubly selective channels with InterCarrier Interference (ICI) are considered.
