针对近年来低轨星座通信系统与地面 IMT 业务系统频率共用兼容性分析中,双方系统在时间维度、空间维度存在大尺度差异的问题,提出一种仿真建模方法,即在传统空间业务系统和地面 IMT 系统建模仿真的基础上,增加以时空换算为手段的微观与宏观系统间映射关系进行建模的仿真方法。
In response to the compatibility analysis of frequency sharing between low orbit constellations and IMT systems in recent years
which has caused large-scale differences in time and spatial dimensions between the two systems
a simulation modeling method was proposed that added a mapping relationship between micro and macro systems used spatiotemporal conversion as a means of modeling on the basis of traditional space business system and ground IMT system modeling and simulation.
