Method for generating single-carrier digital modulation interference signal and interference case library

Abstract

The invention discloses a method for generating a single-carrier digital modulation interference signal and an interference case library, and belongs to the technical field of wireless communication interference. According to the method, a binary single-carrier digital modulation signal is taken as a research object, and an interference signal of the signal under an additive white Gaussian noise channel and a generation method of an interference case library are researched. The method is realized by an interference signal generation system, and the system comprises an interference signal generation module, an interference case library and an interference decision module. According to the system, an interference signal capable of enabling the bit error rate of a single-carrier digitally modulated communication signal to be actually effective is generated through an interference signal generation module; communication signal parameters are changed, generated interference signals are input into an interference case library to be accumulated, finally, interference signals suitable for existing interference equipment resources are output through an interference decision module accordingto enemy communication signals intercepted by the jammer, and the interference signals are closer to actual application occasions.

Description

technical field [0001] The invention relates to a single-carrier DTM interference signal and a method for generating an interference case library, belonging to the technical field of wireless communication interference. Background technique [0002] In modern warfare, communication confrontation in military communication plays a decisive role in strategic offense and defense. Communication confrontation is a combat operation carried out by hostile parties using electronic technology. The purpose is to weaken and destroy the operational effectiveness of the enemy's radio communication system and ensure the normal performance of one's own radio communication system. In a broad sense, communication countermeasures include three parts: radio communication countermeasure reconnaissance, radio communication jamming, and radio communication electronic defense. Among them, radio communication interference is the use of radio communication interference equipment to emit special int...

Problems solved by technology

[0004] In recent years, many literatures have studied the optimal interference patterns for single-carrier digital signals under additive Gaussian white noise channels. Most of them design the interference patterns of interference signals under the premise of obtaining accurate communication signal parameters. The author Xu Tianyu studied the optimal interference pattern of binary single-carrier digital modulation signal in the article "Study on the best interference pattern of single / multi-carrier digital modulation signal [D]" [Harbin: Harbin Engineering University, 2018.], but its design The interference pattern is limited to related interference, and does not consider the influence of the interference signal frequency on the interference effect
