Abstract

We propose two new frequency synchronization methods for the orthogonal frequency division multiplexing (OFDM) system. They have a large estimation range and acceptable precision in the Rayleigh channel. One of the methods does not waste system bandwidth because the training sequence is superimposed on the data of the OFDM symbol. The performance of the two methods is better than that of the method proposed by F. Tufvesson et al. (see Proc. IEEE Vehicular Technology Conf. VTC 1999-Fall, p.2203-7, 1999).
