Under exploiting MIMO-OFDM communication system spatial signal resources, diversity algorithms based on one preamble symbol for MIMO-OFDM frame and symbol timing synchronization are presented in this paper.The diversity method overcome hurdle in timing synchronization performance decline on high speed wireless mulfipath channel deep fading. The detail diversity algorithms aiming for frame and symbol timing synchronization are described. The simulation results for MIMO-OFDM frame and symbol timing synchronization on high speed wireless multipath COST 207 channel model are given.
