Laboratory workplace for measurement of DVB-T2 MISO broadcasting
Bárta, Vojtěch ; Kratochvíl, Tomáš (referee) ; Polák, Ladislav (advisor)
This bachelor thesis deals with measurement and analysis of DVB-T2 MISO broadcasts. The theoretical part of the thesis describes the broadcasting chain of the DVB-T2 system at the level of the physical layers. Attention is paid to both SISO and MISO transmit modes. In the experimental part of the work is to design a measuring workplace for monitoring and analysis of DVB-T2 MISO transmission in laboratory conditions. The functionality of the proposed concept and chosen measuring methodology was verified by a set of experimental measurements.

Slab bridge over the Lužnice River
Bárta, Vojtěch ; Zich, Miloš (referee) ; Panáček, Josef (advisor)
The goal of this bachelor´s thesis is to design a slab bridge over the Lužnice river. The bridge consists of a one span. Implementation was designed in three studies, of which is developed in detail the study of prestressed monolithic slab. To create a static model and to calculate the internal forces is used Scia Engineer 2012. The assessment is processed manually according to European standards. Losses of preload are estimated, the effect of shrinkage and creep is neglected.

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.

Analýza udržitelného rozvoje vybraných států Afriky, se speciálním zřetelem na využití půdy a návrhy rámcových opatření
Bárta, Vojtěch
Abstract Title: Analysis of sustainable development in selected African countries, with special reference to land use and proposals for framework measures. This work consisted of selecting 3 developing countries in Africa according to selected criteria and then analysing pre-determined areas of these selected countries. Subsequently, proposals and measures leading to the promotion of sustainable development of the analyzed countries were built on the analysis. The results of the work were based on the proposals and measures that were established for the individual states, and for the analyzed states in aggregate, concluding the work with a summary of the results in order to prepare them for possible use by anyone, in the further development of this issue. The selected states represented three very diverse territories, including a state whose territory extends into the Sahara Desert. The draft frameworks, which were designed to promote their sustainable development, focused on combating the degradation of the torpid soil type following deforestation, providing water for agriculture and other purposes, combating desertification, agricultural policy and combating corruption. These draft measures were designed to be as feasible as possible, taking into account the lack of resources available to developing countries and other limitations of these territories.

Laboratory Workplace To Measure Dvb-T2 Miso Signal
Bárta, Vojtěch
This article presents a laboratory workplace to measure DVB-T2 MISO signal under laboratory conditions. The performance of DVB-T2 MISO signal influenced by different transmission conditions can be evaluated in terms of the most commonly used objective parameters, like BER before and after channel decoding and MER. Functionality of the proposed concept and the adopted measurement methodology are verified by a set of experimental measurements.
