Secure UAV Communication With Cooperative Jamming and Trajectory Control [PDF]
IEEE Communications Letters, 2019 This paper presents a new cooperative jamming approach to secure the unmanned aerial vehicle (UAV) communication by leveraging jamming from other nearby UAVs to defend against the eavesdropping. In particular, we consider a two-UAV scenario when one UAV transmitter delivers the confidential information to a ground node (GN), and the other UAV jammer ...

Analysis of cooperative jamming against pulse compression radar based on CFAR
Eurasip Journal on Advances in Signal Processing, 2018 One important issue in radar jamming is the effect of inaccuracies in the radar position, which leads to a number of false targets entering the reference window of the constant false alarm ratio (CFAR) detector to reduce greatly.

Cooperative jamming via spectrum leasing [PDF]
2011 International Symposium of Modeling and Optimization of Mobile, Ad Hoc, and Wireless Networks, 2011 Secure communication rates can be facilitated or enhanced via deployment of cooperative jammers in a multi-terminal environment. Such an approach typically assumes dedicated and/or altruistic jamming nodes, investing their resources for the good of the whole system.

Cooperative jamming for wireless physical layer security [PDF]
2009 IEEE/SP 15th Workshop on Statistical Signal Processing, 2009 Cooperative jamming is an approach that has been recently proposed for improving physical layer based security for wireless networks in the presence of an eavesdropper. While the source transmits its message to its destination, a relay node transmits a jamming signal to create interference at the eavesdropper.

Cooperative Jamming and Relay Selection for Covert Communications
CoRR, 2023 This paper investigates the covert communications via cooperative jamming and relay selection in a wireless relay system, where a source intends to transmit a message to its destination with the help of a selected relay, and a warden attempts to detect the existence of wireless transmissions from both the source and relay, while friendly jammers send ...
