Patent ID: 7190929

Claim:
An assigning system for assigning a plurality of tracking units of a wireless receiver, the wireless receiver being utilized in a wireless communication system to receive a plurality of external multipath signals in a predetermined time period for reconstructing correspondingly an original signal, the plurality of tracking units tracking a plurality of path signals in each multipath signal according to a plurality of correspondingly predetermined tracking time positions, the assigning system comprising: a searcher for searching the plurality of path signals in the multipath signal with a first predetermined resolution, and accordingly acquiring a plurality of corresponding searching time positions; a range estimator for estimating the plurality of searching time positions and the first predetermined resolution via a predetermined range estimating process, and accordingly acquiring a plurality of tracking ranges corresponding to the plurality of searching time positions; and an assigning management unit for comparing a tracking range corresponding to a target searching time position of the plurality of searching time positions with the plurality of predetermined tracking time positions, and accordingly assigning the plurality of tracking units; wherein, if there are more than one predetermined tracking time positions within the tracking range, the assigning management unit assigns any tracking unit corresponding to one of the predetermined tracking time positions to track the path signal corresponding to the target searching time position; if there is only one predetermined tracking time position within the tracking range, the assigning management unit assigns the tracking unit corresponding to the predetermined tracking time position to track the path signal corresponding to the target searching time position; if there is no predetermined tracking time position within the tracking range, the assigning management unit assigns an idle tracking unit to track the path signal corresponding to the target searching time position according to the target searching time position corresponding to the tracking range.
