%X A new time and frequency synchronization method based on frequency domain correlation for an Orthogonal Frequency Division Multiplexing (OFDM) system is presented. The time synchronization and carrier frequency offset estimation can be achieved simultaneously. The algorithms described here use one training sequence of just one symbol and the design of the symbol is presented. The carrier offset estimation can be got by the correlation result of time synchronization and the frequency synchronization algorithm can extend the frequency acquisition range to nearly the whole useful OFDM signal bandwidth. The efficacy of the synchronization algorithms is demonstrated experimentally.
