Abstract :
Matched filter (MF) time and frequency synchronization method for orthogonal frequency division multiplexing (OFDM) systems is presented. The proposed method uses the same pseudo-noise (PN)-preamble generation as was used in [1], but signal processing in the receiver is different. The performance of the proposed method is investigated using theoretical and simulated synchronization probabilities. The obtained results indicate that the proposed synchronizer attains the optimum theoretical performance.
