Analog Network Coding (ANC) as a simple implementation of physical layer network coding based on Orthogonal Frequency Division Multiplexing (OFDM) has been proposed to increase the network capacity and reliability of bi-directional link between a pair of users. In ANC protocol, an information between a pair of users is exchanged through two orthogonal time phases (i.e., multiple-access and broadcast phases). On the other hand, the Phase Noise (PN) introduces phase offset and Inter Carrier Interference (ICI) to the useful signal. Thus, in ANC scheme PN will affect the useful signal during both multiple-access and broadcast phases. In this paper, the authors present a performance analysis of ANC scheme using OFDM in the presence of PN in frequency-selective fading channel.
