Measurement and analysis of the DAB system
Kaštánek, Petr ; Kufa, Jan (referee) ; Polák, Ladislav (advisor)
This thesis deals with the measurement and analysis the performance of the Digital Audio Broadcasting (DAB) system. Theoretical part of the work contains a brief description of the signal processing chain of DAB. Attention is devoted to physical layer (PHY). In the experimental part of the work is designed and implemented laboratory measuring workplace for reception, processing and evaluation of DAB signal. The RTL2832U software defined radio (SDR) is used as a receiver of the DAB signal. The functionality of the proposed concept is verified by a detailed measurement.

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.

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.

Laboratory Workplace For Performance Measurement Of The Dab/Dab+ System
Kaštánek, Petr
In this paper, a simple laboratory measurement workplace, proposed for educational purposes, to measure the performance of the DAB/DAB+ signal is presented. The RTL2832U software defined radio (SDR) is used as a receiver of the DAB signal in the measurement setup. Freeware available program DAB Player is used to analyze the DAB signal on the objective and subjective level. The functionality of the proposed concept as well as the applied measurement methodology is verified by simple experimental measurements.

Laboratory Workplace For Measuring Performances Of Dvb-T2/T2-Lite Systems
Krejčíř, Dominik
This paper presents a simple measurement setup to explore performances of DVB-T2/T2-Lite systems. The proposed concept is realized in a form of measurement workplace in laboratory conditions and an appropriate measurement methodology is adopted. It is possible to measure objective parameters of the DVB-T2/T2-Lite signal or evaluate its performance subjectively. Functionality of the proposed concept is verified by a set of experimental measurements.
