ABSTRACT:
The present invention is an assigning system and method for assigning a plurality of rake finger tracking units of a rake receiver in a Code Division Multiple Access (CDMA) communication system. The plurality of rake finger tracking units is used for tracking a plurality of path signal of each multipath signal by a plurality of corresponding predetermined tracking time positions. The assigning system and method estimate a plurality of corresponding tracking ranges of the plurality of path signals and compare the plurality of predetermined tracking time positions with the plurality of tracking ranges. If there is more than one predetermined tracking time positions in one tracking range, the assigning system assigns a rake finger tracking unit corresponding to one of the tracking time positions to track the path signal corresponding to the tracking range. If there is no predetermined tracking time position in the tracking range, the assigning system assigns an idle rake finger tracking unit to track the path signal corresponding to the tracking range. By the way, the present invention uses the rake finger tracking units of the rake receiver with the best efficiency to avoid the idle resources of the communication system.
