全国地面数字电视700兆赫频率迁移工作已经基本完成,地面数字电视可用频率资源紧缺,组建地面数字电视单频网成为解决该问题的最佳方案.如何确保地面数字电视单频网成功组网以及稳定运行成为地面数字电视系统运行和维护的重要工作.本文通过分析在700兆赫频率迁移项目单频网验收测试工作中遇到的实际案例,发现了单频网组网在实际操作中可能出现的问题,给出了排查单频网组网失败问题的具体方法,并总结了消除单频网干扰的工作流程,为地面数字电视单频网运维工作提供了借鉴和参考.
Verification of SFN Networking and Analysis of Networking Failure Cases in 700 MHz Frequency Migration Project
The 700 MHz frequency migration work for DTMB has been basically completed,and the available frequency resources for DTMB are scarce.Establishing a single frequency network for DTMB has become the best solution to solve this problem.How to ensure the successful networking and stable operation of a SFN has become an important task for the operation and maintenance of DTMB systems.This article analyzes the actual cases encountered in the acceptance testing of SFN in the 700 MHz frequency migration project,discovers the possible problems that may occur in the actual operation of SFN networking,provides specific methods for troubleshooting SFN networking failures,and summarizes the workflow for eliminating SFN interference,providing reference and guidance for the operation and maintenance of SFN in DTMB.
