description The invention provides a method for implementing the fine synchronization during cell search. The method comprises the following steps: determining the relevant peak values of each group of code words according to the calculated local code words and the relevant values of the received data; and sorting a plurality of relevant peak values and simultaneously averaging the remaining relevant peak values; determining the ratio of each of the plurality of relevant peak values to the average value of the remaining relevant peak values; comparing the ratios with a preset threshold and recording the code word information corresponding to the ratio beyond the preset threshold; and repeating the pervious procedures in sequence and recording the code word information, and determining the each downlink synchronizing code word of the central frequency point according to the sequence of the occurrence frequency and times. The invention also provides a device and a mobile terminal for implementing the fine synchronization d
