河北省中央节目地面数字电视覆盖网优化研究

Optimization Research on DTMB Networks for CCTV Programs of Hebei Province

概括介绍了河北省频率规划方案,逐一确定了网络优化工作所需的技术参数,重点分析了网络优化工作的原理和方法。通过区域单频网和多频网实例,解决了存在的干扰问题,提出了河北省中央节目地面数字电视覆盖网组网的优化参数和方案,为其他省份开展类似工作提供了技术参考。

The work introduced by this paper is part of the DTMB coverage project for CCTV programs. In this paper, the DTMB frequency plan of Hebei province is summarized. The technical parameters for network optimization are determined one by one. The principle and method for network optimization are mainly analyzed. The interference problems are solved in case studies of municipal SFNs and MFNs. The optimized parameters and scheme used tot DTMB networks for CCTV programs of Hebei province are put forward. The work may provide technical reference for other provinces.
