Abstract

We propose an advanced time synchronization scheme with additional pre-processor for OFDM systems. The proposed pre-processor scheme makes symbol synchronization and guard-interval length detection possible, even though there is no guard-interval length information. This pre-processor is so useful in the systems like DVB-T, which have several kinds of guard-interval lengths. Simulation results show that the proposed scheme gives satisfactory performance in the guard-interval length detection and the OFDM symbol synchronization over AWGN.
