| Abstract: | A new method is discussed based on Schmidl＆cox. A new training symbol has been designed and the affection of CP to the synchronization has been considered in the new method. Combining impwved Schmidl＆cox training symbol with CP is used to achieve the synchronization timing of symbols. The computer simulates the improved method and the simulation results suggest that the performance of synchronization is improved. |
