摘要
5G通信技术的飞速发展,助力社会经济建设,提高了人们的生活水平。但是5G通信信号会严重干扰卫星电视信号,对卫星电视信号产生不良影响。对此,通过对5G通信技术与卫星电视信号的研究分析发现,两者在频率波段上存在重叠现象,在某些频段出现相互干扰的情况,严重影响卫星电视业务。针对这一现象,提出设立干扰协调区域及保护间距、增加卫星电视信号的接收链路、采用窄带高频头消除干扰信号、用大口径卫星接收天线减少干扰、用C波段滤波器抑制信号以及加增屏蔽网等解决措施,来保障卫星电视信号不受5G信号的干扰。
The rapid development of 5G communication technology has helped social and economic construction and improved people’s living standards.However,5G communication signal will seriously interfere with satellite TV signal and have a negative impact on satellite TV signal.In this regard,through the research and analysis of 5G communication technology and satellite TV signals,it is found that they overlap in frequency bands and interfere with each other in some frequency bands,which seriously affects satellite TV services.In view of this phenomenon,it is proposed to set up interference coordination area and protection spacing,increase the receiving link of satellite TV signal,eliminate interference signal with narrow-band tuner,reduce interference with large-diameter satellite receiving antenna,suppress signal with C-band filter and add shielding network,so as to ensure that satellite TV signal is not interfered by 5G signal.
