Air-to-Ground Two-Phase Covert Transmission Aided by a Full-Duplex UAV Relay
This paper investigates an air-to-ground two phase covert transmission (AtG-TPCT) system, which is associated with an unmanned aerial vehicle transmitter Alice (UAV-A), a fullduplex UAV relay (UAV-R) and multiple uncertainly located wardens. Accordingly, given the bounded location uncertainty of wardens, we formulate a...
