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.
