摘要：
A novel method for the blind estimation of carrier frequency offset for orthogonal frequency division multiplexing (OFDM) is proposed. It is based on the second-order statistic algorithm. A special subcarrier weighting function is employed, which makes the estimation of the carrier frequency offset in an unknown multipath channel very efficient. Simulation results have demonstrated the effectiveness and robustness of the proposed algorithm.
