无锡地面数字电视覆盖与同频干扰分析和测试

摘要

In this paper, the planning process for coverage of 33 channel DTTB in Wuxi is discussed. It analyzes the coverage effect and co-channel interference of analog TV by theoretical calculation and coverage simulation, considering mansion and Er Mao-feng launch. Also, the result of practical measuring proves that the planning is feasible. The coverage planning can provide reference for DTTB in other cities.%介绍了无锡DS-33频道地面数字电视的覆盖规划过程,通过理论计算和覆盖仿真,详细分析广电大厦发射点、二茅峰发射点的覆盖效果以及对周边城市同频道模拟电视信号的干扰情况,并由实际测试结果验证规划的可行性,为其他城市的地面数字电视覆盖规划提供参考.
