Summary: | The present invention provides a downlink synchronization method and device used for communicating system. The downlink synchronization method includes the following steps: obtaining initial data and calculating the energy sum of a plurality of initial data segments with the scheduled length; performing slide correlation to each of the N downlink synchronous codes with the initial data, and calculating the energy value of each correlative value to obtain N groups of correlated energy values, where N is an integer greater than 1; using the energy sum of the plurality of initial data segments to respectively perform energy normalization to each group of the N group of correlated energy values; and using the N group of correlated energy values after energy normalization to determine the downlink synchronization code of the target cell and its location in the initial data. |
