摘要
分别介绍了由国际电联(ITU)推荐的世界数字无线电组织DRM和美国iBiquity数字公司带内同频IBOC2个可实现30MHz以下地面数字音频广播的系统方案的技术要点和指标,并对2个方案进行了对比研究,提出了对发展中国数字调幅广播的建议。
Digital Radio Mondiale (DRM) and iBiquity Digital's In-band On-Channle (IBOC) are two schemes of terrestrial digital audio broadcasting under 30 MHz recommended by ITU. In this paper, the major techniques adopted by these two systems are introduced. Based on the prudent comparison and analysis, some comments are made for the development of digital AM audio broadcasting in China.
