Research on Three-Dimensional Geometry-Based Channel Modeling for Power Internet of Things Communications

  • 摘要: 当前研究主要采用椭圆模型描述第6代 (6G)电力物联网(IoT)物理层多节点通信场景,忽视了信号传输路径的俯仰角对系统性能造成的影响。为解决这一问题,该文通过建立3维半椭球体几何传输模型描述6G电力物联网物理层通信场景,提高了电力物联网异构网物理层数据传输分析过程中的准确度。在提出的传输分析算法中,通过推导电力物联网通信无线传输信道中不同传输路径的复冲激响应函数表达式,揭示物理层数据的传输特性。数值分析不同传输路径间的互相关特性,探索电力物联网的时域传输特性,验证上述信道传输特性仿真结果的正确性,对于分析与设计电力物联网无线通信系统具有重要的理论依据和技术支撑。
