摘要
通过部署智能电磁表面来实现无线传播环境的智能重构是目前6G研究的一个关键,其信道建模是后续进行智能电磁表面规划部署、覆盖/容量及其他网络性能分析的基础.在基于地图(map-based)混合信道模型基础上,基于射线追踪及可控智能电磁表面反射模型给出了一种适用于智能电磁表面部署在复杂实际场景中的信道建模方法。该方法通过把电磁表面建模为由不同来波所激励的多个虚拟逻辑基站,在保持较高精度的基础上,简化了模型算法,降低了运算量,为6G无线传播环境的智能重配研究打下了基础.
One of the crucial aspects in the 6G research is to realize the intelligent reconfiguration of radio channel by deploying intelligent electro-magnetic-surfaces and the channel modeling in this area is the fundamental for future deployment and planning of electro-magnetic-surfaces as well as the analysis of coverage,capacity and other performance of network.In this article,the methodology of channel modeling is presented based on map-based hybrid channel model,ray tracing technology and the model of electro-magnetic surface reflection,which is suitable for the electro-magnetic-surface being deployed in a complex scenario.The proposed algorithm simplifies the modeling procedure and decreases the calculation loaded by modeling the intelligent electro-magnetic-surfaces as the multi-vitural logical base stations stimulated by multi-imping waves,which establishes the basis for the research of intelligent reconfiguration on radio propagation environment.
