Multihop FD Relaying with Fixed and Random Phase Errors

This paper investigates the error rate performance of a multihop decode and forward (DF) relaying systems, in which all the relays are considered to operate in full-duplex mode. The effect of residual self-loop interference (RSLI) is characterized as a fading effect and modeled with the generalized Nakagami-m distribution. We also consider the effect of the random and fixed phase errors on the performance of gray coded M -ary phase shift keying (MPSK). The random phase errors, which are assumed to be caused by imperfections in the phase locked loop (PLL), are characterized by von-Mises distribution. All the analytical results presented in this paper are supported by Monte Carlo simulations.
