In this paper, we provide an exact analysis of phase-noise effects on orthogonal frequency division multiplexing (OFDM) performance. We focus on the phase-noise inter-carrier interference (ICI) and derive a closed-form expression for the signal-to-interference-noise ratio (SINR), which helps in understanding how system behavior changes with a certain parameter. An ICI reduction (ICIR) scheme was proposed in [14] and the algorithm performance over AWGN channel was thoroughly studied. In this paper, we further extend this work to Rayleigh fading channel and investigate the effects of multipath fading on the phase-noise mitigation. It is shown by the study that the ICIR algorithm reduces the phase-noise ICI a great deal before channel estimation and improves greatly system performance. Finally, numerical results show the effectiveness of the proposed approaches. |
