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.

FSO transceiver for link quality estimation
Novák, Marek ; Vlček, Čestmír (referee) ; Wilfert, Otakar (advisor)
Tato diplomová práce pojednává o zmírnění bitové chybovosti bezkabelového optického spoje s užitím principu reciprocity aplikovaného na komunikační kanál, spolu s možností kódování přenášených dat. V této práci je implementováno LDPC a Reed-Solomonovo kódování pro jejich vyhovující vlastnosti. Zbytková rámcová chybovost je vypočtena a k dispozici jako výstup systému, který je implementovaný v hradlovém poli (FPGA).

Simulation of the RF transmission channel for the DVB-T2
Strouhal, Adam ; Hüttl, Ondřej (referee) ; Polák, Ladislav (advisor)
This Master thesis is focused on detailed description of the DVB-T2 system. This work deals with the description of the particular parts of models and with typical RF transmission channels for fixed and mobile reception. In order to simulate the impact of the fading transmission channels on the transmitted signal there was developed an appropriate application in MATLAB. The graphic user interface of this application allows set the transmission parameters of DVB-T2 and the parameters of the transmission channels. Results of simulations with various settings are evaluated and compared with the results, obtained from the DVB-T measurements.

Simulation of the DVB-S2 Transmission
Klíma, Jindřich ; Fliegel, Karel (referee) ; Kaller, Ondřej (advisor)
This thesis is focusing on the second satellite digital TV standard, DVB-S2. It deals with the principle of the digital TV and the first standard DVB-S. It also describes the very beginning and characteristics of the DVB-S2, new technologies in use, architecture and the individual topics are then explained more in detail. The thesis also contains the program of transmission simulation of DVB-S2 in MATLAB. In the laboratory of television technology UREL, two standards were measured and compared with the values obtained from the program. The functionality of the program and the benefits of DVB-S2 were verified afterwards.
