In this paper we present an analytical approach to evaluate the M-QAM bit error rate and carrier frequency dependent throughput of OFDM systems subject to various receiver impairments and mobile channel characteristics. Specifically we model the following effects: residual carrier frequency offset, outdated channel state information due to user mobility, channel estimation errors and flat receiver I/Q imbalance in Rayleigh time and frequency selective fading channels. We provide a numerical tool to evaluate the uncoded bit error rate as well as mutual information in the case of scattered pilot designs used for pilot-aided linear channel estimation and linear channel interpolation.
