This work proposes suitable network configurations for single frequency networks (SFNs) with ATSC 1.0 based on network coverage calculations and the laboratory multipath handling performance of commercial receivers. SFNs are widely used for delivering terrestrial digital television services because of their efficient use of the spectrum. In Mexico the analogue television transmissions switch-off occurred on 31 December 2016. Thus it is expected the adopted ATSC 1.0 system will be in force for the next several years despite the recent standardization of the ATSC 3.0 system. As ATSC 1.0 uses 8-VSB modulation the multipath handling capability of receivers is critical for the design of SFNs. The presented network planning results help develop technical normativity for implementing SFNs in Mexico and other countries that use ATSC 1.0. SFNs with transmitter separation up to 130 km are fully covered for outdoor reception mainly due to the directivity of the receiving antenna. Moreover for indoor reception at least 70% of an SFN coverage area can be achieved with a transmitter separation of up to 60 km depending on the radiated power and the transmitter antenna height.

基于接收机多径处理性能的ATSC 1.0单频网络设计参数分析

这项工作基于网络覆盖计算和商业接收器的实验室多径处理性能,为采用 ATSC 1.0 的单频网络 (SFN) 提出了合适的网络配置。SFN 因其对频谱的高效使用而被广泛用于提供地面数字电视服务。在墨西哥,模拟电视传输关闭发生在 2016 年 12 月 31 日。因此,尽管最近对 ATSC 3.0 系统进行了标准化,但预计采用的 ATSC 1.0 系统将在未来几年内生效。由于 ATSC 1.0 使用 8-VSB 调制,因此接收机的多径处理能力对于 SFN 的设计至关重要。所呈现的网络规划结果有助于制定在墨西哥和其他使用 ATSC 1.0 的国家实施 SFN 的技术规范性。主要由于接收天线的方向性,发射机间隔达 130 公里的 SFN 完全可以用于室外接收。此外,对于室内接收,根据辐射功率和发射机天线高度,发射机间隔可达 60 公里,可实现至少 70% 的 SFN 覆盖区域。
