摘要
阐述了移动通信发展过程中电磁环境的变化,以及伴随的移动通信电磁兼容的发展,并从三个方面对5G移动通信面临的电磁挑战进行了讨论:一是电磁环境的复杂性、融合性;二是M-MIMO架构下5G基站的电磁兼容挑战与解决方案;三是5G移动通信电磁环境标准的研究与演进。最后,探讨了未来移动通信几种可能的新场景以及需要面对的电磁环境挑战,提出了EMC分析方法及工具可能的演进路径,即从基于工程最优思想的设备电磁兼容顶层设计,到室内近场时间反演的自适应时空聚焦,再到大尺度可编程电磁环境。
This paper first describes the evolution of the electromagnetic environment during the development of mobile communications and the development of the electromagnetic compatibility.Then,the electromagnetic challenges of 5G communication are discussed from three aspects,1)the complexity and integration of the electromagnetic environment,2)EMC challenges and solutions for 5G basestation in the M-MIMO architecture,3)the research and evolution of 5G communication electromagnetic environment standards.Finally,the possible new scenarios and electromagnetic environment challenges for future mobile communications are discussed,a possible evolution path of EMC analysis methods and tools is given,from electromagnetic compatibility top-layer design based on the optimal engineering idea to adaptive space-time focusing with indoor near-field time reversal to large scale programmable electromagnetic environment.
