提出了一种基于延迟锁定环的混合相位共轭器（DLL-HPC）作为5G波束成形的可能解决方案。理论背景，独特的能力，和实验验证。所提出的DLL-HPC提供了与现有波束形成协议的向后兼容性，以及亚毫秒波束控制和零通信开销的自动移动的目标跟踪。概念验证DLL-HPC原型已由商用组件构建，可在5G NR-FR 1频段运行，这表明该技术可以通过现有技术轻松采用。
A delay-locked loop based hybrid phase conjugator (DLL-HPC) is presented as a possible solution for 5G beamforming. Theoretical background, unique capabilities, and experimental verification are presented. The proposed DLL-HPC provides backwards compatibility with existing beamforming protocols as well as sub-millisecond beamsteering and automatic mobile target tracking with zero communication overhead. A proof-of-concept DLL-HPC prototype has been constructed from commercially available components to operate in the 5G NR-FR1 band, indicating that the technique can be readily adopted with available technology.
