摘要:

针对宽频段压制干扰威胁以及频谱资源与通信抗干扰能力之间的固有矛盾,提出在扩谱抗干扰基础上增加统计域维度的方法,推动通信抗干扰由“硬抗”向“容扰”转变。盲源分离抗干扰技术利用通信信号和干扰信号的统计特性差异进行信号分离,可在不增加频谱资源条件下提高通信抗干扰能力。为认识和完善盲源分离抗干扰从理论算法到工程实践的发展过程,阐述盲源分离通信抗干扰技术的基本原理,重点介绍多通道盲源分离、单通道盲源分离等关键技术,分析盲源分离通信抗干扰技术的主要特点和存在的问题,最后指出该领域的发展重点。

Abstract:

Aiming at the threat of broad frequency band suppressing jamming and the inherent contradiction between spectrum resources and communication anti-jamming ability, a method was proposed to add the statistics domain dimension on the basis of spread spectrum anti-jamming, which promoted the transformation of communication anti-jamming from hard anti-jamming to accommodate the jamming.The statistical characteristics difference between communication signal and jamming signal was utilized by blind source separation (BSS) communication anti-jamming technology to separate signals, which could improve the communication anti-jamming ability without increasing spectrum resources.To understand and improve the development process of BSS communication anti-jamming (BSSCA) from theory and algorithm to engineering practice, the basic principle of BSSCA was described, the key technologies such as multi-channel BSS and single channel BSS were emphasized.The main characteristics and existing problems of BSSCA were analyzed.Finally, the development priorities of this field were pointed out.

Key words: wireless communication, communication anti-jamming, blind source separation, independent component analysis, empirical-mode decomposition
