%X This paper analyzes the performance of fine time synchronization which using cross correlation method and gives the relationship between its performance and the parameters of carrier frequency offset and signal to noise ratio. Then this paper proposal a new fine time synchronization method which is less affected by frequency offset. This paper gives the upper limit for synchronization sequence length in a certain frequency offset. In new method, synchronization sequence is split into several parts and correlates with receive signal separately. The delayed correlation values for every segment are added to get the synchronization metric. The simulation results demonstrate that the performance of the new method is robust against frequency offset.
