摘　　要：进入新世纪以来,社会经济和科技的进步极大地改变了人们的生活生产方式,提升了人们获取信息的便捷度。5G网络因高传输速率、低时延、强连接成为商用首选。然而,5G基站增多,与广播电视C频段频率较为接近,因此对广播电视接收站的正常运行造成了严重影响。基于此,分析5G与卫星信号干扰的原理,提出加装滤波器预防干扰,并验证其效果。测试表明,加装滤波器可显著减少或消除5G信号的干扰,提高卫星接收系统的稳定性。Since the beginning of the new century,the progress of social economy and science and technology has greatly changed people's way of life and production,and improved the convenience of people's access to information.5G network has become the first choice for commercial use due to its high transmission rate,low delay and strong connection.However,the increase of 5G base stations is closer to the C-band frequency of radio and television,so it has a serious impact on the normal operation of radio and television receiving stations.Based on this,analysis of 5G and the principle of the satellite signal interference,put forward to add filter to prevent interference,and verify its effect.The test results show that the addition of filters can significantly reduce or eliminate the interference of 5G signals and improve the stability of the satellite receiving system.
