摘　　要：物理层安全信号星座的设计方法的核心思想是调整信号星座使窃听者不能正确解码接收到的信息.运用物理层安全信号星座的设计方法可不需要知道窃听者的信道状态信息,并可用实际的调制信号实现安全保密传输.本文介绍物理层安全信号星座的设计方法的技术要点与发展现状,归纳其基本手段、保密性能分析方法、存在的问题和现有的解决方案.最后讨论了物理层安全信号星座的设计方法进一步的研究方向.The core idea of the signal constellation design approach for physical layer security is to adjust the signal constellation so that the eavesdropper cannot correctly decode the received information. Signal constellation design approach for physical layer security does not need to know the eavesdropper＇s channel state information and can use actual modulation signal to achieve secure and confidential transmission. In this paper,we present the technical points and development status of the signal constellation design approach for physical layer security,and then summarize the basic approach,secure analysis methods,existing problems and solutions. In the end,the directions and future works of the signal constellation design approach for physical layer security are discussed.
