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.
