Měření parametrů DVB-T vysílání v jednofrekvenční síti SFN a návrh řešení pro STA ve vybraných problémových lokalitách.

Abstract

This thesis introduces into with signal digitalization area. System is also called DVB-T and has been implemented into every household. Together with implementation of this system spurious signal called „pre-echo „has occurred. It has very bad influence on signal interception in family or prefabricated houses. On some digital receivers which are called SET-TOP-BOX the „pre-echo „effect tends to make screen cube patterns. Customers push on receiver producers for „pre-echo „effect mitigation and service improvement. This thesis is to map few localities digital and with help of signal measuring results try to offer proposel for optimal treatment of „pre-echo „effect in those chosen localities.
