调频频段模数同播系统在北斗地基增强系统中的应用实践

Application and Practice of FM Analog-digital Simulcast System in Beidou Ground-based Augmentation System

广西广播电视技术中心开展利用调频频段模数同播系统播发北斗地基增强差分修正数据的应用实践,数字信号和调频广播信号在同一频点上带内同播,共用一副天线发射。本文介绍了技术方案、实施步骤、播出指标及应用效果。

Guangxi Radio&TV Broadcasting Technology Center carried out application practice of using analog-digital multicast system in FM frequency band to broadcast Beidou ground-based enhanced difference correction data. Digital signal and FM radio signal are transmitted by the same frequency and the same antenna.. This paper introduces technological schemes, implementation steps, broadcasting indicators and application effect.
