摘要
面向900 MHz频段NR网络重耕演进,进行了该频段5G NR系统与邻频DME系统的共存分析。首先介绍了系统干扰模型,而后阐述了系统干扰仿真的实现,包括使用的仿真参数、传播模型及仿真拓扑,并给出了仿真分析结果,最后针对分析结果给出了相关建议。
Aiming at the refarming evolution of 900 MHz band,it analyzes the coexistence of 5G NR system and adjacent frequency Distance Measure Equipment(DME)system in this band.Firstly,the system interference model is introduced,and then the realization of system interference simulation is described,including the simulation parameters,propagation model and simulation topology,and the simulation analysis results are given.Finally,some suggestions are given according to the analysis results.
