Abstract

The invention relates to a background interference noise level prediction method and system. The method comprises: setting relevant background interference noise level mean sequences of a prediction moment and a known time quantum in dependence on the historic background interference noise level mean value data set of a predicted frequency point and a preset perception data effective scope; obtaining a Euclidean distance between the relevant background interference noise level mean sequence of the known time quantum and the relevant background interference noise level mean sequence of the prediction moment; screening a plurality of background interference noise level mean values of the known time quantum corresponding with the Euclidean distance and less than a preset threshold to generate a background interference noise level prediction value set; and performing weight calculation in dependence on the background interference noise level prediction value set to obtain the background interference noise level prediction value of the predicted frequency point at the prediction moment. The background interference noise level prediction method and system analyze historic data through a similarity coupling method, predict a future background interference noise level based on historical data change rules, and possess high prediction precision.

Description

technical field [0001] The invention relates to frequency management technology, in particular to a method and system for predicting background interference noise level. Background technique [0002] The background interference noise is one of the decisive factors affecting the signal-to-interference-to-noise ratio of the receiver, and its prediction accuracy directly affects the accuracy and effectiveness of dynamic frequency management. Background interference noise is the sum of electromagnetic radiation that affects or destroys the normal operation of radio equipment, and is composed of interference signals and background noise. At present, the main technologies surrounding the prediction of background interference noise level are as follows: [0003] (1) Recommendation ITU-R P.372 provides reference values ​​for background noise levels in the range of 0.1 Hz to 100 GHz. This recommendation specifies background noise as the sum of unwanted radiation from various sources...
