Abstract

The physical layer network coding (PNC) takes advantages of signal interference at relay node and improves the channel capacity, therefore, PNC becomes an important research topic. However, the frequency-selective fading channel would destroy the performances of PNC. This paper considers orthogonal frequency division multiplex (OFDM) in PNC, when signals transmitted over a frequency-selective fading channel, and an optimum power allocation scheme is proposed. Simulation results show that the presented system not only eliminates the multi-path interference, but also maximizes the channel capacity by the optimum power allocation.
