%X In this paper, a novel synchronization algorithm is proposed for OFDM based system in multipath fading channels. In order to mitigate the effect of the multipath, the length of the correlation window is adapted according to the channel maximum time delay estimated in the fore frame. And the further fine synchronization is completed using the multipath information estimated in current frame. Simulation results demonstrate that the synchronization performances are improved greatly compared with the conventional methods. And the method is much suitable for the OFDM time synchronization in multipath fading channel environment.
