Title:
CDMA MOBILE COMMUNICATION SYSTEM AND CELL SEARCH METHOD OF MOBILE STATION FOR THE SAME
Document Type and Number:
Japanese Patent JP3794617
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To shorten a cell search time and to improve accuracy of detection.
SOLUTION: A correlative output value of a slot at a prescribed position, which is an object of correlative detection, is acquired at correlative detection of a secondary synchronization channel signal(SSCH). Here, the fluctuation amount of an amplitude and phase on a propagation path are estimated with a correlative output value of a primary synchronization channel signal(PSCH) at a slot at a prescribed position and a plurality of slots before and after the slot or a correlative output value of the secondary synchronization channel signal at a plurality of slots, before and after the slot at the prescribed position as a reference signal.
