Abstract
In the field of wireless communication,COMP(coordinated multi-point transmission)joint communication is widely used because it can enhance the signal quality significantly.In this paper,the COMP technology is proposed to enhance the performance of physical layer information monitoring.Multiple legitimate monitors are adopted to jointly eavesdrop multiple orthogonal suspicious communication pairs.Furthermore,UAV(unmanned aerial vehicle)is utilized to jam these suspicious communication pairs.The aim of this paper is to jointly optimize the location of the UAV as well as the jamming power allocation to maximize the minimum probability of success among multiple suspicious communication pairs.The Monte Carlo method is used to verify the approximate value and exact value of the cumulative distribution function(CDF)of the COMP signal-to-noise ratio(SNR).Given that the proposed optimization problem is highly non-convex,successive convex approximation(SCA)and block coordinate descent(BCD)method are used to optimize the position of the UAV and the jamming power allocation alternately in order to obtain a local optimal solution.Simulation results show that the proposed scheme can significantly improve the minimum eavesdropping success probability of the system in comparison with the other schemes.关键词
