CELL SEARCH OF TIME-OVERLAPPING CELLS IN A MOBILE COMMUNICATION SYSTEM

摘要

A cell search in a spread spectrum telecommunication system is performed by determining a spreading code of an undetected neighbor cell; and de-spreading a received signal using the scrambling code of the undetected neighbor cell at a path delay position of an already-detected cell. The undetected neighbor cell may be identified by means of a neighbor list received from a network of the spread spectrum telecommunication system. A path searcher can be used to perform de-spreading the received signal using the scrambling code of the undetected neighbor cell at the path delay position of an already-detected cell. Concurrently with this operation, a cell searcher can be used to perform a path-masked cell search procedure.
