| Abstract: | In this paper, the testing and analysis methods for coverage of radio and television in tunnels have been discussed. It includes data collection by the outfield test, statistics in EXCEL, simulation of field intensity distribution by MATLAB, and so on. Then the situation of coverage about FM, DTV and CMMB can be mastered. The methods can provide reference for coverage testing in other closed regions such as metro. |
