【Abstract】 Based on the maximum correlation and ensemble correlation methods,a new method of OFDM system timing synchronization based on cyclic prefix is proposed.The new method has higher performance and lower computation cost.The simulation results show that the performance of timing synchronization is better than that of the maximum correlation or ensemble correlation methods over wireless multipath channel.更多还原
