隧道中的广播电视信号覆盖测试

摘要

In this paper, the testing and analysis methods for coverage of radio and television in tunnels are 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.%介绍了隧道中广播电视信号的测试与分析方法,通过移动路测采集数据、Excel表单统计数据、Matlab软件仿真场强分布,全面掌握隧道中调频广播(FM)、移动电视以及CMMB信号的覆盖情况,为地铁等其他封闭区域内的信号覆盖测试提供参考.
