一种无人机毫米波通信用户视距覆盖优化方法
An line-of-sight coverage optimization method for UAV millimeter-wave communication users
摘要
Abstract
In order to solve the problem of significant millimeter-wave-based UAV communication signal of attenuation in the non-line-of-sight environment,this paper proposes a Line-of-Sight Coverage Optimization(LS-CO)algorithm for users.Firstly,according to the user-provided line-of-sight coverage and the maximized sig-nal-to-noise ratio(SNR)between UAVs and users are established the target questions about the UAVs'position and orientation.And then,the problem is transformed into integer linear programming problem and solved by us-ing greedy algorithm based on geometric method.The simulation results show that compared with the benchmark treatment,the proposed LSCO method can meet the requirements of line-of-sight(LoS)coverage,and improve the SNR value between users and UAVs.关键词
