Abstract
In this paper, we apply pilot-symbol-aided estimation technique in time domain to estimate the fractional part of the normalized frequency offset in OFDM system. Moreover, we correct the frequency offset according to a general theoretical model for OFDM with frequency offset. The simulation results prove the estimation of frequency offset is precise, and the correction of frequency offset is very effective.
