Abstract: The present invention provides a method and an apparatus for detecting a synchronization position of an LTE cell. A part of sampling points are selected from all sampling points of received data, where the received data is generated by filtering a local sequence from a base station; correlation operations are carried out on the part of the sampling points, and multiple first correlation results and multiple pieces of first position information that correspond to the part of the sampling points are obtained; and a maximum first correlation result is determined among at least one first correlation result greater than a preset threshold in the multiple first correlation results, and a piece of first position information, which corresponds to the maximum first correlation result, is taken as a synchronization position.
