摘要：

This paper shows how to utilize the Short Training Sequence, Long Training Sequence and Pilot Subcarriers, of the IEEE 802.11a frame, to estimate and equalize the effect of both carrier and sampling frequency offset. To reduce cost the equalization process is performed digitally. Using computer simulation, we show that the presented scheme nearly eliminates the degradation due to frequency offset for all IEEE 802.11a modulation schemes. The performance measures are the root-mean-squared error (RMSE) and BER in a fading channel.
