The authors present an OFDM frequency synchronization scheme. This paper presents an extended solution for the carrier frequency synchronization problem of OFDM. The scheme uses number of bits, modulation level, cyclic prefix, FFT size similarly to the algorithm proposed by Tilde Fusco. The proposed scheme attains considerably higher accuracy than the scheme requiring convolutional encoding data and viterbi decoding technique. Pilot Insertion and Cyclic Extension also included in the synchronization scheme. Their proposed method gives better results for different values of signal to noise ratio.
