摘要
在数字化、信息化的时代背景下,尽快完成传统广播的数字化是广播网最紧迫的任务,而频率规划则是数字广播网络建设的技术基础。本文通过对场强计算中相关技术参数的研究,对中国数字音频广播(China Digital Radio,以下简称CDR)系统在VHF调频频段上的最小中值场强进行推导,对未来CDR系统网络建设具有指导意义。
At the age of digitalization and information, the most crucial task of terrestrial audio broadcasting networks is the completion of transition of digital audio broadcasting. However, the technical foundation of networks construction is the work of frequency planning. In this paper, we study the technical parameters for frequency planning of China Digital Radio system (CDR) in VHF band, and deduce the minimum medium field strength, which is constructive for the development networks of CDR system.
