Embodiment Construction

[0021] In order to effectively improve the accuracy of interference source location, the embodiment of the present invention provides an interference source location method. The interference source location method includes: determining the angle of arrival corresponding to the interference signal collected at each collection point, and determining the Collecting the interference source path trajectory of the collection point, determining the attribute information of each interference signal in each collection point, and according to the determined attribute information of each interference signal in each collection point, and the determined interference source path trajectory , to determine the location of the interference source. Since the interference signals with the same attribute information may be the interference signals sent by the same interference source, in the embodiment of the present invention, the intersection point of the path trajectory determined by the angle ...

Abstract

The invention discloses a method and device for positioning an interference source, and the method and device provided by the invention are used for solving the problems of low accuracy and poor accuracy in positioning the interference source in the prior art. The method comprises: determining an angle of wave approach corresponding to an interference signal collected by each collecting point, and determining the path routing of the interference source passing the collecting points; determining the attribute information of each interference signal in each collecting point; and determining theposition of the interference source according to the attribute information of each interference signal in each determinate collecting point and the determined path routing of the interference source.Because the interference signals with identical attribute information are possibly the interference signals generated by the same interference source, the intersecting point of the path routing determined by the angle of wave approach corresponding to the interference signals with the identical attribute information in the embodiment of the invention serves as the position of the interference source, thereby eliminating the interference caused by the refraction of the signal by buildings and the interference generated by overlapping between different interference source signals effectively, so that the determined position of the interference source is more accurate.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for locating an interference source. Background technique [0002] With the continuous development of mobile communication technology, more and more users own mobile terminals. Therefore, how to provide high-quality services for each mobile terminal user has become the focus of every operator. Because there are a large number of communication devices in the existing communication network, such as blockers, repeaters, etc., and the signals of the same frequency generated by different communication devices will interfere with each other, so there are a large number of communication devices in the communication network. The communication equipment has caused severe interference to mobile communication equipment using the same frequency, affecting the communication quality between mobile communication equipment. [0003] In the prior art, i...
