Network planning for digital terrestrial television and radio broadcasting
Dostal, Radek ; Ulovec,, Karel (referee) ; Kratochvíl, Tomáš (advisor)
Master’s thesis is focused on SFN (Single Frequency Network) and MFN (Multi Frequency Network) networks design in digital television broadcasting based on DVB-T standard and digital radio broadcasting based on T-DAB standard. First part of the thesis is focused on the theoretical description of the MPEG-2 TS transmission, its propagation from transmitter across free space, to be decoded in the DVB-T receiver. In the second, practical part of the thesis, basic parameters of a software package for broadcast network design in RadioLab, RadioBase and Sítě SFN are introduced and the results are displayed on the digital terrain map and morphologic map. Within solution of this thesis was created signal coverage model of DVB-T digital transmitters in entire area of the Czech Republic, so called networks no. 1-4, according to its status in spring 2010, and its future expansion, which is known from TPP (Technical Plan of Conversion) document. At the conclusion of thesis there were made experiments with the modeling of transmitters’ radiated power, guard interval selection and location of DVB-T transmitters in the SFN network.

Performance analysis of SFNs transmitters of DVB-T2
Bárta, Vojtěch ; Miloš, Jiří (referee) ; Polák, Ladislav (advisor)
The diploma thesis deals with the design and analysis of Single Frequency Networks (SFNs) transmitters for Digital Video Broadcasting – second generation of the Terrestrial (DVB-T2). In this thesis, the software of the Czech company CRC data is used. Main attention is focused on the SFN Networks computational system for the analysis and design od DVB-T2 SFN networks, in which a series of simulations of the transmitting Multiplex 21 (CH26) have been performed. The simulation-based results are used to identify locations with lower signal coverage or interfering sources as well as to find appropriate approaches to solve these issues. The rightness of the performed simulations is verified by field measurements in cooperation with the Czech Telecommunications Office (CTU), and finally a discussion on how to improve the performance of SFN networks follows.

SFN and MFN networks design in DVB-T
Dostal, Radek ; Láčík, Jaroslav (referee) ; Kratochvíl, Tomáš (advisor)
Bachelor’s thesis is focused on SFN (Single Frequency Network) and MFN (Multi Frequency Network) networks design in digital television broadcasting based on DVB-T standard. First part of the thesis is focused on the theoretical description of the MPEG-2 transport stream and basic parameters of broadcasting network, transmitters and transmission path. In practical part are introduced basic parameters of a software package for broadcast network design in RadioLab, RadioBase and Sítě SFN, and results displayed on the digital terrain map and morphologic map. Within solution of this thesis was created signal coverage model of digital transmitters in entire area of Czech Republic, so called networks no.1-4, according to its status in spring 2008. Next is focused on government order about convert from analog to digital video broadcasting terrestrial.
