Abstract:
1. A reassigning system for reassigning a plurality of tracking units of a wireless receiver for receiving a plurality of multipath signals in a predetermined time period to reconstruct a correspondingly original signal, the reassigning system comprising: a searcher for searching a plurality of peaks in a multipath signal with a first predetermined resolution, and accordingly acquiring a plurality of corresponding searching time positions; a tracker comprising the plurality of tracking units, each of the tracking units tracking a corresponding peak value with a predetermined tracking time position and according to a second predetermined resolution wherein the second predetermined resolution is higher than the first predetermined resolution; and an assigning management unit, wherein the assignment management unit comprises: wherein the assigning management unit reassigns the plurality of tracking units to track the plurality of multipath signals according to the relationship of the searching time positions and the predetermined tracking time positions in the acquired combination of matching pairs from the assigning module; and wherein the estimating module generates the assigning value corresponding to each combination of matching pairs by using: means for subtracting the searching time position and from predetermined tracking time position of every matching pair in the combination of matching pairs and taking absolute values to obtain a plurality of corresponding subtraction values; means for inputting the plurality of subtraction values to a predetermined estimating function to obtain a plurality of corresponding estimation values; and means for summing up the plurality of estimation values and obtaining the assigning value of the combination of matching pairs.
