A novel frequency offset estimation algorithm for Orthogonal Frequency Division Multiplexing(OFDM) signals transmitted over frequency-selective channels is analyzed. The algorithm is discussed with channel zeros and arbitrarily assignment of null-subcarriers. The effect of distribution of null subcarriers and channel zeros is discussed. An adaptive assignment of null-subcarriers scheme is proposed. The proposed algorithm performs significantly better than the already existing methods.
