Paper Abstract

A new frequency synchronization method is proposed in this paper. It uses PN (pseudo-noise) sequences and cyclic prefix for synchronization in OFDM (orthogonal frequency division multiplexing) system. Several subcarriers estimation range can be reached using the new method. When cyclic prefix is used in fine frequency synchronization, the MSE (mean square error) of the proposed method is less than the method only used PN sequences for the span of the correlated data is large. This has been verified by simulations in AWGN channel and Rayleigh channel.
