摘要
工信部正式发布了5G系统中频段的频率使用规划,其中3300MHz?3600MHz范围段和我国C波段卫星电视业务存在干扰可能。为了保证两者之间避免有害干扰而保持正常运营,需要开展干扰共存研究。本文主要针对5G系统基站对C波段卫星电视接收系统的干扰分析,通过测试干扰模型计算出基站设立参考,并提出协调解决5G系统通信基站与卫星地球站及接收站的电磁兼容共存方法。
MIIT has officially issued a frequency utilization plan for 5G system,in which the range of 3300MHz-3600MHz and Chinese C-band satellite TV business may have interference.In order to avoid harmful interference and maintain normal operation,it is necessary to carry out interference coexistence research.This paper mainly analyzes the interference of 5G base station to C-band satellite TV receiving system,to establish base station establishment by the interference model,and puts forward a coordinated solution to electromagnetic compatibility coexistence of 5G base station with satellite earth station and receiving station.
