Özet

A time domain carrier frequency offset estimation method is proposed for OFDM systems. The essence of the proposed method is based on the correlation features of short and long synchronisation symbols, which appear at the beginning of each frame as the training sequence. The noise effect on the estimation is minimised by averaging over several estimations. The time-domain operations and correcting bigger carrier frequency offsets compared to the work by P.H. Moose are the important features of this study. The proposed method has a lower complexity and better BER performance for higher frequency offset values comparing to the referenced studies.
