Patent ID: 7149241

Claim:
A mobile station in a CDMA communication system, the mobile station comprising: a plurality of finger sections in each of which each of plural radio waves being arrived from a base station through a plurality of paths is inversely spread to regenerate data from said base station; and a finger allocating section for allocating a path timing corresponding to each peak position of said plurality of radio waves to each of said plurality of finger sections, each of said plurality of radio waves being inversely spread in a path tracking range among segments positioned before and after the path timing allocated by said finger allocating section, said path tracking range in each of said plurality of finger sections being variably determined based on the respective distances between peak positions of said plurality of radio waves, said path tracking range being broadened when said distances are large, and said path tracking range being narrowed when said distances are small, and said path timing range being independently determined for each of said plurality of finger section.
