Zusammenfassung:	The invention provides a TD-LTE synchronization method and synchronization device, and the method comprises the steps: processing a received TD-LTE downlink signal, obtaining an input signal comprising a TD-LTE downlink PSS (primary synchronization signal), carrying out the correlation operation of the input signal an a local PSS, obtaining a correct PSS code in local PSS codes and a first position frame corresponding to the maximum value of all correlation values, carrying out the correlation operation of the input signal comprising the TD-LTE downlink PSS with the correct PSS code in local PSS codes, and generating a synchronization indication signal at a correct position frame based on the correct PSS code and the first position frame corresponding to the maximum value of all correlation values when a correlation signal outputted after correlation operation meets a preset condition. The method solves technical problems that the processing rate is low during the TD-LTE downlink synchronization, the precisio
