Abstract:
1. A mobile communication system receiver which, based on a delay profile of multipath multiplexed signals to be received, separates/extracts each path contained in multipaths, demodulates received signals by each of the separated paths, and performs rake combine on the demodulated signals, the receiver comprising a path allocation unit for separating/extracting each path contained in the multipaths and allocating the separated/extracted paths to demodulation finger receivers, wherein the path allocation unit comprises: a grouping unit which puts the paths into an independent path and paths of an adjacent path group when separating/extracting each path from the multipaths based on the delay profile; a judging unit which judges each of the paths allocated by the grouping unit to find out whether the path is a single path or not, and whether the paths are the paths of the adjacent path group or not; and a path tracking processing unit which sets priority orders to the paths that are contained in the adjacent path group, sets path tracking regions and mask regions to each of the paths of the adjacent path group according to the priority orders, and executes path tracking processing for each of the paths of the adjacent path group.
