Executive Summary

In this paper, the authors present a numerical approach to evaluate the Bit Error Rate (BER) and mutual information of OFDM links subject to phase noise, channel estimation error and frequency selective fading channels. Based on the analytical modeling of the correlation between channel estimates and received signals affected by phase noise, the statistical properties of the received signal can be numerically evaluated by means of a probability density function. The results illustrate that their analysis can approximate the simulative performance very accurately if the power delay profile of the fading channels and the phase noise properties are known.
