Method for performing radio signal precise interference analysis by use of K chart

Abstract

The invention discloses a method for performing radio signal precise interference analysis by use of a K chart. The method comprises the following steps: firstly acquiring long-time full-band monitoring data containing frequency, amplitude and time by use of GPS time-service cooperative work based on a dedicated scanning monitoring control module, and storing the monitoring data; tracing out a change process chart of the signal amplitude with time based on scanning data acquired by a monitoring station, namely the K chart of the invention; displaying frequency data by use of the K chart; and computing an original signal capable of producing inter-modulation interference signal, calling an activity rule curve chart of each of the original signal and the interference signal in the same time slot to display on the same K chart, thereby judging two radio interference types of inter-modulation interference and same-frequency multiplexing. Through the adoption of the method disclosed by the invention, the immediate troubleshooting efficiency of the radio interference is improved, and the radio communication order is preferably maintained.

Description

technical field [0001] The invention relates to the technical field of wireless station monitoring, in particular to a method for precise interference analysis of radio signals by using K-line diagrams. Background technique [0002] In our daily radio management, a considerable part of radio interference is generated by intermodulation. This is because the transmitting devices of different frequencies are set up too close and too densely, and some of the transmitting devices receive signals transmitted by other transmitting devices and generate intermodulation products of a new frequency inside them, and the intermodulation products are then transmitted The radio interference generated by the equipment after amplification is called intermodulation interference. [0003] The search for intermodulation interference has always been a difficult problem for us, because first of all, it is not generated by an independent radio device, it is the result of the joint action of multi...

Problems solved by technology

Secondly, when performing intermodulation interference analysis, there are often many pairs of stations that can cause intermodulation interference, and they need to be checked one by one. The entire investigation takes a long time and is inefficient.
