  • Abstract
    An optimal maximum likelihood (ML) estimator of the time and frequency offset in OFDM systems is presented. The optimal ML estimator fully exploits the redundant information in the cyclic prefix of the OFDM symbol. Simulation results indicate that the optimal ML estimator outperforms an existing suboptimal ML estimator.
