摘      要：Unmanned Aerial Vehicle(UAV) is an air base station featuring flexible deployment and *** can significantly improve the communication quality of the system due to its line-of-sight channel connection with ground ***,due to the openness of UAV-to-Ground channels,the communication between ground users devices and UAV is easily *** this paper,we aim to improve the security of communication system by using full-duplex UAV as a mobile air base *** UAV sends interference signals to eavesdroppers and receives signals from ground *** jointly optimize the scheduling between the UAV and ground devices,the transmission power of the UAV and ground devices,as well as the trajectory of the UAV to maximize the minimum average security communication data *** optimization problem is mixed with integers and nonconvex ***,this problem is not a standard convex optimization problem,which can not be solved with standard *** this in mind,we propose an effective algorithm which solves this problem iteratively by applying Successive Convex Approximation(SCA),variable relaxation and ***,numerical results demonstrate the effectiveness of the proposed algorithm.
