Apparatus and method for searching for cell and multi-path in mobile communication system

摘要

A method for performing a third cell search process or a multi-path search process to detect a scrambling code used by a Node B or in a Mobile Station by generating at least one scrambling code; determining one of first and second methods, in which the first method calculates correlation energy values of reception signals associated with at least two scrambling codes sequentially generated with predetermined time delays, and the second method sequentially generates one scrambling code with the predetermined time delays, and calculates correlation energy values of the reception signals associated with the generated scrambling codes; calculating correlation energy values of the reception signals associated with the generated scrambling codes according to the determination result; and determining a scrambling code used by the Node B or multi-paths to be assigned to individual fingers of a rake receiver using the calculated correlation energy values associated with the scrambling codes.
