Problems solved by technology
The main work of the finger manager 16 is to allocate and manage the finger tracking units 12, and the known finger managers cannot effectively solve the above problems, so that the finger tracking units are unnecessarily redistributed, making the rake The time for the tracking signal of the receiver increases, which results in the reduction of the performance of the overall rake receiver. Therefore, the present invention is aimed at the problem that the rake finger tracking unit is idle or tracks a signal with a long distance on the time coordinate. Propose an efficient method for allocating finger tracking units to reduce unnecessary finger tracking unit allocations and thus improve system performance

Embodiment Construction
[0024] When the wireless receiver is processing multi-path signals, the speed of the tracking unit when tracking each path signal and the precise tracking signal determine the overall performance of the wireless receiver. If the tracking unit can quickly track the exact position of the path signal, the accuracy of the signal processing by the wireless receiver will be greatly improved. The present invention provides a system and method for effectively allocating finger tracking units to accurately track multiple path signals searched by a searcher. The system and method of the present invention can effectively reduce the possibility of the tracking unit tracking wrong path signals, thereby improving the accuracy of the whole wireless receiver in processing multi-path signals.
[0025] see figure 2 , figure 2 It is a schematic diagram of the system structure of a preferred embodiment of the present invention. The present invention provides an assignment system 20 for reass...

A distributing system incldues the searcher, the tracker and the distribution manager. The searcher searches path signals in the multiple path signals so as to obtain the multiple searched time coordinates. The tracker contains multiple harrow-finger tracing units and each unit possesses the relevant presetting tracing time coordinate in order to trace the position of the path signals. The distribution manager pairs the searched multiple time-coordinates and the preset tracing time-coordinates off so as to obtain the multiple paired combinations. Then, the optimal paired combination is found out from the multiple paired combination. Based on the paired relationship between the searched time-coordinates and tracing time-coordinates, the tracing region testing is carried out.
Description
technical field [0001] The present invention relates to a system and method for allocating a plurality of finger tracking units in a rake receiver, in particular to a method by re-pairing the search time coordinates of each path signal with the tracking time coordinates of the finger tracking units, A system and method for redistributing rake finger tracking units through an optimal pairing combination. Background technique [0002] In recent years, in the personal mobile communication system, the code division multiple access (CDMA) communication system has attracted more and more attention from everyone, such as the third generation mobile communication system using the direct sequence code division multiple access (DS / CDMA) technology, It is developed based on code division multiple access communication technology. In the spread spectrum communication (Spread Spectrum Communication) system, multipath propagation has a great influence on the commu...
