Abstract
One of the ways to clarify the zones of a television signal’s confident reception in single-frequency networks (SFN) DVB-T2 deployed on previously existing infrastructure of analog signal’s television is considered. A simulation model of the SFN broadcasting consist of module of the propagation of radio waves, module of a transmitting station, module of a receiving station and a geoinformation system. It has been revealed that the DVB-T2 broadcasting modes, the effective antenna suspension heights and the effective radiated power of transmitters, which are used in DVB-T2 broadcasting, can lead not only to the appearance of areas of intra-character interference with reduced television signal quality inside the service area, but also to the effect of the so-called "intra-network amplification". The discrepancy between the used protective interval (PI) and the topology of the studied OSS has been established.
