摘要:

在物理层安全技术的研究中,协作干扰技术是较为特殊的一类,通过引入人为的干扰信号,降低窃听节点的接收性能,进而提升系统的保密容量。本文回顾了协作干扰技术的提出背景,总结了其研究现状,并对未来的发展前景和潜在研究点进行了展望。目前协作干扰技术的研究可以根据干扰信号的不同分为4类,也可根据窃听系统的不同分为简单和复杂场景下的自干扰和外协作干扰技术的研究。

Abstract:

In the research of physical layer security, cooperative jamming is a special and novel research area. The artificial jamming signal is introduced into the wire-tap system to interfere the eavesdroppers and decrease their signal-to-interference-plus-noise ratios, then the system secrecy capacity can be improved. The background and state-of-the-art of cooperative jamming were reviewed and the future potential research topics were pointed out. Currently, the artificial jamming signal can be divided into four categories. Additionally, in the research of cooperative jamming, self-jamming and introducing jamming systems are investigated with simple and complex scenarios.

Key words: wireless communication, physical layer security, wire-tap channel, cooperative jamming
