MA辅助MISO系统中的隐蔽通信研究
Research on Covert Communication in MA-Assisted MISO Systems
摘要
Abstract
This study aims to investigate the covert throughput-constrained problem in movable antenna(MA)-assisted multiple-input single-output(MISO)systems.The research focuses on maximizing the covert communication rate through optimizing the MA positions,leveraging the additional spatial degrees of freedom of MA for flexible beamforming matrix design.A branch-and-bound algorithm is proposed for the joint optimization of MA positions and beamforming,ultimately enhancing the throughput of covert communication systems while ensuring covertness requirements.Theoretical analysis and simulation results validate the effectiveness of the proposed algorithm.关键词
