联合多用户调度与协作干扰选择的无线物理层安全研究
Physical Layer Secrecy Analysis of Joint User Scheduling and Jammer Selection
摘要
Abstract
Physical layer security (PLS) is an effective means to protect communications against eaves‐dropping attacks by exploiting physical characteristics of wireless channels .As the information and com‐munication technology (ICT) has been developed for decades ,PLS attracts more and more attention of researchers .Here ,PLS performance of the joint multi‐user scheduling and the cooperative jammer selec‐tion is explored .With the combination of the two techniques ,the wireless communication security is in‐vestigated .In a wireless communication system with multiple users ,multi‐user scheduling schemes are adopted to choose one legitimate user of the best channel to transmit signals .Meanwhile ,the eavesdrop‐pers are interfered to keep the transmissions between BS and legitimate users confidential for avoiding the interference to the legitimate users .CJ signal is designed so that nulls are formed at the legitimate users . Simulation results show that the joint multi‐user scheduling and cooperative jammer scheme has a better performance of security than the multi‐user scheduling scheme .关键词
