摘　　要：本文研究了5G系统与广播电视卫星接收系统的干扰共存问题。确定了5G信号干扰类型,建立了单链路干扰模型,制定了干扰保护准则,对已知5G干扰信号源进行了确定性分析,在不同参数条件下利用MATLAB对干扰状态进行了模拟仿真,同时提出了卫星接收系统抗5G干扰的有效措施。相关研究结果可作为行业内5G干扰卫星信号问题的参考借鉴。This paper studies co-existing interference between 5G system and radio and television satellite receiving system.In the paper,interference types of 5G signals are determined,single-link interference model is established,interference protection criteria is formulated,deterministic analysis of known 5G interference signal source is carried out,interference state is simulated with MATLAB under different parameters,and effective measures against 5G interference in satellite receiving system are also proposed.Relevant research results can be used as a reference in the industry for 5G interference satellite signal problems.
