Planning of Single Frequency Networks for DVB-T2

Abstract

Nowadays, especially in Europe, the second generation of Digital Video Broadcasting Terrestrial system, abbreviated as DVB-T2, gradually replaces its predecessor DVB-T. Compared to DVB-T, DVB-T2 is a more versatile system with several configuration settings. Thanks to this, the planning of Single Frequency Networks (SFNs) used to effectively cover a certain area by DVB-T2 signal can be more flexible and straightforward. This paper deals with the design of SFNs for DVB-T2, especially with focus on the study of DVB-T2 system parameters (e.g. guard interval) and transmission conditions (e.g. multipath propagation) directly affecting performance of SFNs. For this purpose, RadioLab, RadioBase and Networks SFN utilities from CRC data software are used. Real DVB-T2 system configuration for Multiplex 21 (MUX 21) used in Brno (Czech Republic) is employed in this study. The simulation-based results can help to identify places with lower signal coverage or interfering sources as well as to find appropriate approaches to solve these issues.
