Problems solved by technology

The existing spectrum prediction technology has high requirements on the training time and the number of training samples. When the training sample data is small, the prediction effect is often not ideal.
At the same time, there are few researches at home and abroad on the reliable spectrum prediction technology based on small samples of man-made interference signals in the channel.

Abstract

The invention relates to a cognitive radio interference prediction method and system. The method comprises: analyzing historical frequency spectrum information and looking for interference patterns; analyzing the interference patterns and finding the optimal access frequency band; and realizing dynamic access of the communication frequency band according to the obtained optimal access frequency band. The system comprises a sensor node, a communication node and a management center. The nodes work in conjunction with each other according to the above cognitive radio interference prediction method. The invention guarantees that proactive frequency spectrum shifting be realized when cognitive users are communicated, thereby preventing confliction with interference.

Description

technical field [0001] The present invention relates to the field of cognitive radio technologies, in particular to a cognitive radio interference prediction method and system. Background technique [0002] With the rapid development of mobile communication technology, new wireless communication services emerge in an endless stream, the number of users continues to increase, and spectrum resources become increasingly scarce. In order to improve the utilization efficiency of wireless spectrum, cognitive radio (CR, CognitiveRadio) technology is proposed. Cognitive radio technology can realize dynamic spectrum allocation and spectrum sharing through spectrum detection and intelligent learning capabilities of the system. [0003] The anti-jamming capability is an important index to measure communication equipment under the conditions of modern warfare, and it is also an important guarantee for winning the war. Cognitive radio has advanced machine learning capabilities, which c...
