Recommendation ITU-R BS.1660-7
(10/2015)
Technical basis for planning of terrestrial
digital sound broadcasting in the VHF band

Broadcasting service (sound)
ii Rec. ITU-R BS.1660-7
Foreword
The role of the Radiocommunication Sector is to ensure the rational, equitable, efficient and economical use of the radio-
frequency spectrum by all radiocommunication services, including satellite services, and carry out studies without limit
of frequency range on the basis of which Recommendations are adopted.
The regulatory and policy functions of the Radiocommunication Sector are performed by World and Regional
Radiocommunication Conferences and Radiocommunication Assemblies supported by Study Groups.
Policy on Intellectual Property Right (IPR)
ITU-R policy on IPR is described in the Common Patent Policy for ITU-T/ITU-R/ISO/IEC referenced in Annex 1 of
Resolution ITU-R 1. Forms to be used for the submission of patent statements and licensing declarations by patent holders
are available from http://www.itu.int/ITU-R/go/patents/en where the Guidelines for Implementation of the Common
Patent Policy for ITU-T/ITU-R/ISO/IEC and the ITU-R patent information database can also be found.

Rec. ITU-R BS.1660-7 1
RECOMMENDATION ITU-R BS.1660-7*
Technical basis for planning of terrestrial digital sound
broadcasting in the VHF band
(Question ITU-R 56/6)
(2003-2005-2005-2006-2011-2012-2015)
Scope
This Recommendation describes the planning criteria, which could be used for planning of terrestrial
digital sound broadcasting in the VHF band, for Digital Systems A, F and G of
Recommendation ITU-R BS.1114.
The ITU Radiocommunication Assembly,
considering
a) Recommendations ITU-R BS.774 and ITU-R BS.1114;
b) ITU-R Digital Sound Broadcasting Handbook Terrestrial and satellite digital sound
broadcasting to vehicular, portable and fixed receivers in the VHF/UHF bands,
recommends
1 that the planning criteria as described in Annex 1 for Digital System A and Annex 2 for
Digital System F and Annex 3 for Digital System G could be used for planning of terrestrial digital
sound broadcasting in the VHF band.
Annex 1
Technical basis for planning of terrestrial digital sound
broadcasting System A (T-DAB) in the VHF band
1 General
This Recommendation contains relevant T-DAB system parameters and network concepts, including
a description of single frequency networks (SFNs).
The receiving antenna, which is assumed to be representative for mobile and portable reception, has
a height of 1.5 m above ground level, omnidirectional with a gain slightly lower than a dipole.
The field strength prediction method relies on curves for 50% locations, 50% time for the wanted
signal and 50% locations, 1% time for the unwanted signal.
For the calculation of tropospheric (1% time) and continuous (50% time) interference, see
Recommendation ITU-R BT.655.
* The Administration of the Syrian Arab Republic is not in a position to accept the content of this
Recommendation, nor for it to be used as a technical basis for the planning of sound broadcasting in the VHF
band, at the forthcoming Regional Radiocommunication Conferences planning of the digital terrestrial
broadcasting service in parts of Regions 1 and 3.
摘要:

本文档标题为《ITU-R BS.1660-7-2015 地面数字声音广播甚高频(VHF)系统计划的技术基础》,是国际电信联盟无线电通信部门(ITU-R)发布的一项重要技术标准。该标准为全球地面数字声音广播在甚高频(VHF)频段的系统规划与部署提供了关键技术基础和指导原则。BS.1660-7版本涵盖了系统参数、频谱规划方法、干扰协调机制以及覆盖预测模型等核心内容,旨在确保不同国家和地区在VHF频段实现高效、可靠且兼容的数字声音广播服务。对于广播工程师、频谱管理机构以及广电行业从业者而言,理解本标准
