In SC-FDE (single carrier with frequency domain equalization) systems, the factor which affects the performance of systems seriously is synchronization. Based on the studying of the algorithm of T.Schmidl & D.Cox and H.Minn, a novel timing synchronization method is proposed towards the SC-FDE systems in this paper. The method takes advantage of the correlation of the training symbol what can efficiently improve the veracity of timing and the ability of anti-muti-path. Finally the performance of the proposed algorithm is compared with the algorithm of T.Schmidl & D.Cox and H.Minn by computer simulation and the simulation results confirm the superiority of the proposed algorithm.
