Simulation of the DVB-C2 transmission
Chovaneček, Libor ; Fliegel, Karel (referee) ; Kratochvíl, Tomáš (advisor)
The theme of this thesis is simulation of DVB-C2 transmission. The first part of this thesis is focused mainly on theory, where it describes differences between digital and analog television transmission. The project also explains principle of operation DVB-C and DVB-C2 systems with focus on channel coding a modulation. Application for simulation of DVB-C2 transmission, which is developed in the MATLAB environment is described in the second part. The last part of this thesis includes results of simulations of DVB-C2 transmission and their comparison with measured values of DVB-C transmission.
Simulation of the DVB-C and DVB-C2 transmission and their comparison
Cibulka, Tomáš ; Hüttl, Ondřej (referee) ; Polák, Ladislav (advisor)
This Master thesis deals with description, analysis and simulation of standards of digital video broadcasting DVB-C and DVB-C2. There is described mainly the transmission system, channel coding, type of modulation and OFDM symbols generation. Furthermore, channel models, used for the exploring of their performances are described too. There was created an application with a graphical interface in MATLAB, which simulates transmission in DVB-C2. Based on simulations there are compared influences of each settings on bit error rate of data transmission for both standards. Finally, obtained simulation results are compared with theoretical values.
Comparison of modern television broadcast standards
Musil, Karel ; Vaněk, Jiří (advisor) ; Pavlík, Jan (referee)
This bachelor thesis is thematically focused on modern TV broadcast standards. The emphasis is on the future development and possibilities. The first part provides a comprehensive overview of the main topic addressed in terms of significant changes in the second generation of digital technology. Including methods currently tested. The greatest emphasis is placed on terrestrial broadcast due to the significance of this method in the Czech Republic and currently ongoing transition to the second generation of broadcasting. The second part focuses on the analysis of the actual developments, and the not too distant future of the television broadcasting. The actual situation of the auction of frequencies is introduced together with the estimation of the allocation of the spectrum. Analyses the potential costs for the viewer and the signal provider, and compare the status of broadcasting in Europe with the situation in the Czech Republic. Further, are defined and analysed the possibilities of the next development of the terrestrial broadcasting.
