Abstract
A method for quickly searching a cell at a mobile station by using a synchronization channel structure of a forward link in a code division multiple access system which operates by an asynchronous mode between base stations is provided. In the method, a predetermined starting point among a plurality of locations of sync channel codes in a frame with respect to a base station having a minimal channel loss is obtained. Long code group and frame sync information at the mobile station are obtained based on outputs of a matched filter every mini slot clock location for one frame time after a starting point of a current mini slot. A long code based on the obtained long code group and frame sync information obtained is detected wherein the long code is used for band-spreading of a forward link by a current base station.
