Abstract

The invention proposes a communication interference detection method based on the Gaussian eye pattern texture entropy feature, which mainly solves the problems of low detection rate and long detection time under low interference-to-signal ratio in the existing interference detection method. The implementation steps are: (1) generate the Gaussian eye diagram of the wireless communication signal to be detected; (2) calculate the texture entropy feature of the Gaussian eye diagram; (3) set the interference detection test statistics; (4) perform the inspection and judgment to obtain Interference detection results. The present invention has the advantages of high interference detection probability and fast detection speed under high and low interference-to-signal ratios, and effectively overcomes the low detection probability and long detection time existing in existing interference detection methods. question.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and further relates to a communication interference detection method based on the texture entropy feature of a Gaussian eye diagram in the technical field of signal and information processing. The invention can be used to detect noise modulation interference signals of wireless communication systems and communication countermeasure systems. Background technique [0002] Noise-modulated interference signal refers to the electronic interference that modulates the frequency, amplitude and phase of the signal with low-frequency random noise. It is a common type of interference signal in communication systems. If the communication system is disturbed, it will seriously affect the communication quality. If the interference signal can be effectively detected, and then corresponding anti-interference measures are adopted, the reliability and accuracy of the communication system can be imp...
