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
