地面数字电视单频网覆盖效果监测系统研究

Research on Monitoring System of DTMB SFN Coverage

本文讨论一套基于分布式技术的地面数字电视单频网覆盖效果监测系统,用户能够通过使用本系统实时掌握地面数字电视单频网覆盖区域覆盖效果,主要包括信号质量、信号交叠区的接收效果等。系统可以对地面数字电视信号进行解调,处理信号的各项参数信息,利用现有通信网络,将监测设备采集到的数据回传到监测系统服务器,进行分析和处理。

This paper is focus on a system of DTMB SFN coverage quality monitoring. The indicators of the DTMB SFN coverage quality, such as signal level, BER, and reception quality, are transfered by the 3G/4G network to the monitoring server. Users will see all those indicators from the web UI provided by the system.
