Abstract-- In this paper we investigate the error probability
for OFDM with carrier frequency offset (CFO) in additive white
Gaussian noise (AWGN) and Rayleigh fading channels. The
statistical nature of the intercarrier interference (ICI) due to CFO
and the validity of the usual Gaussian distributed ICI assumption
are studied. In AWGN channels, our simulations indicate that
the theoretical symbol error rate (SER) obtained by assuming
Gaussian characteristics for the ICI is not accurate. The effect of
adjacent channel ICI coefficients must be considered. However in
a fading channel provided that the channel correlation effects on
the useful OFDM signal and the ICI are considered, the theoret-
ical BER results due to Gaussian ICI approach and simulations
closely agree. The theoretical SER for MQAM signaling in fading
