Abstract: We extend the nearest neighbor approximation method and investigate the symbol error rate (SER) over AWGN channels for physical layer network coding with high order modulation. We derive a closed-form expression of PNC’s SER with 8PSK modulation over AWGN channels. We find that, when the power of one source node is fixed, SER of PNC does not monotonously decrease with the increase of the power of the other source node. Simulation results show that the derived SER expression can characterize the SER performance of PNC’s SER with 8PSK modulation over AWGN channels.

Key words: physical layer network coding, 8PSK modulation, symbol error rate (SER)
