摘　　要：本文在介绍江西省中央无线覆盖工程的基础上,结合江西七○七高山发射台基础在江西省中央无线覆盖工程中的天馈线系统设计方案进行了剖析。同时,在江西省中央无线覆盖工程省级单频网优化工作中,介绍了针对高山发射台覆盖特点,进行规划参数调整,进而实现优化覆盖的大区域单频网覆盖优化方法。本文所做工作和研究,能够为高山发射台更好地服务我国未来地面数字电视的发展提供工程经验与技术支撑。Based on the introduction of central wireless coverage project in Jiangxi Province, this paper analyzes a design of antenna feeder system in the central wireless coverage project in Jiangxi Province, combining with the foundation of the 707 transmitting station in Jiangxi Province. Meanwhile, in the provincial single-frequency network optimization of the central wireless coverage project in Jiangxi, a large-area SFN coverage optimization method for transmitting station on high mountains is introduced, considering the coverage characteristics and the parameter adjustment. The work and research done in this paper provide engineering experience and technical support for the development of mountain transmitting station, and for a better DTTB service in China.
