ABSTRACT:
A method and a device for detecting a synchronization signal with a high identification rate are provided, which are suitable for a wide-area Orthogonal Frequency Division Multiplexing (OFDM) system. The method and device can precisely detect information of a synchronization signal, without being interfered by transmission channels and noises in an external environment. Three sliding windows are used to obtaining a balance value as an offset value for the output signal of the method and the device. A peak position of the output signal is identified and then compensated for a delay caused by the length of one of the sliding windows. Such a position is an edge of the synchronization signal.
