In this paper, we present a novel data-based method for simultaneous Maximum Likelihood (ML) symbol and carrier-frequency o畇et estimation in Orthogonal frequencydivision multiplexing (OFDM) systems. Statistical properties introduced by the cyclic pre痻, a guard space between OFDM symbols, provide su眂ient information about the unknown parameters. It is shown that the redundancy introduced by this cyclic pre痻 allows the estimation to be performed without additional pilots. Simulations show that the performance of the frequency estimator is applicable in a tracking mode while the timing estimation can be used in an acquisition mode.
