Abstract

The present invention provides a multipath positioning method and system for a code division multiple access communication system, wherein the multipath positioning method for a code division multiple access communication system includes: obtaining an initial multipath position according to a baseband signal; According to the occurrence times of the multipath initial location, the multipath initial location is selected as the multipath final location. Here, according to the number of occurrences of the multipath initial position, the multipath initial position is selected as the multipath final position, thereby avoiding operations with a large amount of calculation such as descrambling and despreading calculations and smoothing calculations, that is, compared with the prior art For the multipath positioning method, the calculation amount is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a multipath positioning method and system for a code division multiple access communication system. Background technique [0002] In a code division multiple access (CDMA) communication system, the receiving end mostly uses a RAKE receiver to combine the obtained multipath signals to increase the receiving gain. The RAKE receiver has high requirements on the accuracy of the multipath position, so for the CDMA communication system, it is particularly important to accurately capture and lock the multipath signals on each receiving branch in time. [0003] Existing multipath positioning methods suitable for CDMA communication systems mainly contain two schemes: one mainly completes the acquisition of multipath signals, that is, the multipath search process; Multipath management process for further processing of multipath search results. It is mainly to adjust the resu...
