空中智能反射面赋能的通信抗干扰传输方法研究
Anti-Jamming Communication Transmission Powered by Aerial Intelligent Reflecting Surfaces
摘要
Abstract
To address the issue of susceptibility to ground-based malicious jamming attacks in wireless communication scenarios,this paper investigates a communication anti-jamming transmission method empowered by aerial intelligent reflecting surface(AIRS)technology.AIRS effectively overcomes the problem of signal blockage between base stations and users due to obstacles in complex communication scenarios by dynamically enhancing user signals and suppressing malicious interference signals to improve communication performance.The proposed method achieves the maximum system sum-rate through jointly optimizing the base station transmit power,the deployment of AIRS positions,and the AIRS phase shift matrix.Due to the multi-variable coupling and non-convexity,it is difficult to directly solve the formulated optimization problem.Therefore,this paper proposes an alternating optimization-based algorithm framework,where the successive convex approximation and semidefinite relaxation techniques are used to find the suboptimal solutions for sub-problems.Simulation results show that the optimized scheme can significantly improve the system's anti-jamming communication performance and ensure the reliability of communication data transmission.关键词
