摘　　要：2020年3月25日,工业和信息化部就700 MHz频段频率使用规划做出通知。700 MHz频段原为广播电视业务所使用,许多无线话筒也使用这个频段,造成了业务上的重叠。针对此问题,以5G基站对无线话筒接收系统的干扰为例展开分析,提出避免同频干扰和邻频干扰、保证无线话筒音频质量的对策。On March 25,2020,the Ministry of Industry and Information Technology issued a notice on the frequency use planning of 700 MHz band.The 700 MHz frequency band was originally used for radio and television services,and many wireless microphones also used this frequency band,resulting in overlapping services.In order to solve this problem,the interference case of wireless microphone receiving system is analyzed by 5G base station,and the countermeasures to avoid co-frequency and adjacent frequency interference and ensure the audio quality of wireless microphone are put forward.
