Abstract

The physical layer of IEEE802.16e is based on orthogonal frequency division multiplexing (OFDM) modulation which is particularly sensitive to the timing synchronization. This paper gives a new method based on the idea of difference. The new method can confront frequency-offset when it is in the moment of the symbol timing synchronization and reduce the computation complexity. In the new method, the sequences of the receiver and the sequence of the local reference short preamble are made difference respectively; Then the two difference sequences are made cross-correlation. Finally the peak value is judged. The new method is simulated which show a good performance.
