  abstract={In this paper physical layer network coding (PLNC) in two-phase two-way 
relaying networks using coded orthogonal frequency division multiplexing
(OFDM) transmission is investigated. After receiving the superimposed 
signal from both sources, the relay estimates the XOR-based network 
coded signal, which is broadcast back to the sources. Assuming that the 
relay is equipped with multiple antennas, the uplink transmission forms a
multiple-input multiple-output (MIMO) system, which allows the 
application of MIMO detection technologies. To this end, the impact of 
employing multiple antennas at the relay on different detection and 
decoding schemes under investigations is studied and compared with 
respect to mutual information (MI). Numerical simulations verify our 
theoretical analysis.
