METHOD AND APPARATUS FOR CONTROLLING RAKE FINGER IN CLOSELY SPACED MULTIPATH ENVIRONMENT OF MOBILE COMMUNICATION SYSTEM

摘要

A kind of method and apparatus are arranged to obtain multipath diversity income for controlling a rake finger in the multipath environment of a small―gap suture of a mobile communication system by distributing multiple fingers in a closed position. One device, for controlling a rake finger in the multipath environment of a small―gap suture of a mobile communication system, including a searchers (420), a group determination unit (412), a path status setting device (414), a finger allocation unit (416) and a weight value α applying unit (418). Searchers extracts the location information of intensity and the multipath signal being received. Group's determination unit receives location information from searchers, determines multiple paths as the cluster base on location information. Path status setting device receives the intensity information of searchers, receives cluster information from group's determination unit. Path status is arranged device and a path status is arranged, based on the intensity information for including path in group. Finger base of the finger allocation unit distribution on the path state information from path status setting device. Weight value α applying unit puts on the path state information from path status setting device using a track direction weight value α base.
