Radio wave propagation interference and compatibility analysis in ITU-R
-
摘要: 对国际电信联盟无线通信部第三研究组干扰与兼容性分析相关的标准文本(建议书、手册、报告等)进行了系统的整理与分析，介绍了导致无线电信号干扰的主要传播机理，对于标准文本中干扰与兼容性分析的传播模型进行了简要的介绍，给出了相关传播模型和标准的最新进展，对于标准与模型的发展趋势进行了展望。Abstract: The standard texts (Recommendations, Manuals, Reports, etc.) in ITU-R SG3 related to the interference and compatibility analysis are systematically organized and analyzed in this contribution. The main propagation mechanisms leading to radio signal interference are introduced. The propagation models of interference and compatibility analysis are also briefly introduced. In particular, the latest developments of related propagation models and standards are also given in this paper, while the development of standards and models is proposed in the conclusion.
