摘要
为了解决5G通信基站对C波段单收地球站的干扰共存问题,选取一个干扰的实例作为研究对象,分析干扰成因,并通过实测数据得出带外抑制比ACLR是影响邻频干扰大小的主要因素。根据地球站的干扰保护准则并通过工程实践,可计算得出两系统邻频共存时需要保持的ACLR。
In order to solve the interference coexistence issue of 5G communication base station to C-band single-receiving earth station,this paper selects an interference example as the research object,analyzes the cause of interference,and obtains that ACLR (Adjacent Channel Leakage Ratio) is the main factor affecting the adjacent frequency interference strength through measured data.According to the interference protection guidelines of the earth station and the engineering practice,the ACLR that maintains the coexistence of the two adjacent frequency systems can be calculated.
