摘要
毫米波频段的通信与感知面临两方面挑战:感通干扰制约彼此性能,耦合作用规律及解耦方法尚不成熟;毫米波强指向性特点导致信息传输存在安全隐患。针对智能交通系统感通算融合网络的物理层安全问题,定义泛在感知、潜在通信、融合计算与内生安全的概念,刻画四者的耦合作用关系;梳理感通算安的研究现状及局限性,阐述资源优化分配、感通耦合干扰认知与建模、感通安性能制约机理等的可行思路。
Communication and sensing in the millimeter-wave(mmWave)frequency band face two major challenges.In‐terference between sensing and communication limits their respective performances,and the coupling mechanisms and decoupling methods are still underdeveloped.The strong directionality of mmWave leads to potential security risks in in‐formation transmission.To address the physical layer security in the ISAC network of intelligent transportation systems,the concepts of ubiquitous sensing,potential communication,integrated computing,and inherent security,and character‐izes the coupling relationships among them were defined.The current research and limitations of sensing,communica‐tion,computation,and security were reviewed,and feasible approaches for resource optimization,cognitive modeling of sensing-communication coupling interference,and the mechanisms constraining the performance of sensing-communication enabled security were presented.
