Research on Co Frequency Interference Test Method in Electromagnetic Environment of Metro Communication System
With the continuous development of communication technology,the subway commu-nication system is faced with increasingly serious electromagnetic environment interference.It is necessary to find the interference source in time in the preliminary investigation and preliminary design stage,and avoid interference signal by technical means,so as to ensure the communica-tion quality of signal.A test method of the co-frequency interference in the electromagnetic environment of subway communication system is introduced,the purpose of which is to verify whether there is interference signal of metro communication system in different frequency bands.The test method is operable,and the test results provide a basis for subway designers to optimize the system design scheme,which is an essential part of the subway system before completion and acceptance.
