Abstract
In this paper a novel feedforward frequency synchronizer for orthogonal frequency division multiplexing (OFDM) signals transmitted over multipath fading channels is described. Its derivation is based on maximum likelihood (ML) estimation techniques and assumes an approximate statistical knowledge of the communication channel. The performance of the proposed algorithm is assessed by computer simulations and is compared with that provided by other synchronizers and with Cramer-Rao bounds.
