The doctor study programme provides the specialised university education to the graduates of the previous master study in electronics and communication technologies. The students are educated in various branches of theoretical and applied electronics and communication techniques. The students make deeper their theoretical knowledge of higher mathematics and physics, and they earn also knowledge of applied informatics and computer techniques.
They get ability to produce scientific works.

The doctors are able to solve scientific and complex engineering tasks from the area of electronics and communications.
Wide fundamentals and deep theoretical basis of the study program bring high adaptability and high qualification of doctors for the most of requirements of their future creative practice in all areas of electronic engineering and communications.
The doctors are competent to work as scientists and researchers in many areas of basic research or research and development, as high-specialists in the development, design, construction, and application areas in many institutions, companies, and organisations of the electrical and electronic research, development, and industry as in the areas of communication and data transmission services and systems, inclusively in the special institutions of the state administration. In all of these branches they are able to work also as the leading scientific-, research-, development- or technical-managers.

1. Adaptive OFDM

   The work is oriented into the domain of multicarrier systems using OFDM principle. The aim of the work is to design new algorithms for multicarrier system adaptation to external conditions (SNR, fading etc.). The proposed methods are assumed to work in cognitive radio applications. The system parameters like number of subcarriers have to be adapted to actual situation in the channel (presence of primary users). The developed algorithms should be implemented in FPGA or DSP devices.

2. Advanced Models of EMI Filters

   The project is focused on the analysis of EMI filters performance and on creating their models. The models will have to respect the real circuitry of the EMI filter. The models itself have to contain the spurious parameters which degrade the filters performance in higher frequency range. The parameters of the filters for models will be taken from the measured data in common measuring systems. The modern optimization method should be necessary to use during the creation of filter models. The project has to have also the analysis of the worst-case performance analysis of tested filters.

3. Analysis and optimization of DVB-T/H digital television broadcast networks

   The doctoral theme is focused on analysis of SFN (Single Frequency Network) and MFN (Multi Frequency Network) broadcast networks parameters for digital television according to DVB-T/H standard. With the analysis is essential focus on coverage criteria of useful signal transmitters set and interference influence evaluation on signal coverage. Further analysis deals with time synchronization in networks, guard interval evaluation, according coverage evaluation and network design parameters optimization. The conditions of network design are results of regional conference RRC06. For the analysis is available commercial SW called "SFN Networks" (SW interface only in Czech) or self-created evaluation algorithms for radio signals propagation in terrain profile in limited area. The aim of the work is evaluation of the SFN and MFN networks parameters influence on required coverage and evaluation of the transmitters requirements for the same reason.

4. Analysis and simulation of the signals transmission in DVB-H/SH standard

   The doctoral theme is focused on signal processing and transmission analysis of digital television for mobile terminals in DVB-H (Handheld) and DVB-SH (Satellite Handheld) standards. These standards deal with the reception characterized by the model of transmission channel with multipath reception and Doppler shift (i.e. "portable" and "mobile" reception). Prerequisite of the successful analysis is design of convenient simulation model of the transmission and digital modulation with optional parameters of each block and their software application (Matlab, Simulink). Model of the transmission channel should be designed with the possibility of multipath reception and selective fading simulation. The aim of the work is evaluation of the modulator and transmission channel parameters on achieved bit-error rate and quality of the transmission.

5. Analysis and simulation of the signals transmission in second generation DVB standards

   The doctoral theme is focused on signal processing and transmission analysis of digital television for DVB-S2/C2/T2 transmissions. According to available information these standards and their proposals deal with the data capacity increase, N stage single- and multi-carriers modulations, MIMO systems, alternative way of channel equalization and signaling of transmission parameters and possibility of new services (HDTV, Video on Demand, interactive services etc.). Prerequisite of the successful analysis is design of simulation models of the transmission and digital modulations with optional parameters of each block and their software application (Matlab, Simulink). The aim of the work is comparison of second generation DVB standards performance parameters and their transmission characteristics with the first generation standards (DVB-S, DVB-C a DVB-T) and critical discussion of achieved results.

6. EMI Three-Phase Filters Performance Analyses Under Uncertain Conditions

   The project is focused on the analysis of three-phase (or multiphase) EMI filters. The analysis has to be focused on the uncertain impedance termination of the EMI filters. The termination has a dominant influence on the filter's insertion loss and also on so call "worst-case" performance. The results will be checked by a lot of measurements and also several mathematical analyses. For these analyses will be designed accurate filter's models.

7. Modeling of periodic structures in time domain by method of moments

   The project is focused on the research of numerical methods in the time domain for modeling periodic structures of infinite size based on the Floquet's theorem and the periodic Green's function. Further attention of the project should be concentrated on modeling periodic structures of finite size. The emphasis will be put on the efficiency and stability of solution. Developed methods will be used for the analysis of frequency-selective surfaces and metamaterials.

8. Modulation identification for cognitive radio applications

   The cognitive radio approach is supposed to be used in future communication systems. The cognitive transmitter performs the spectral analysis and in the case of free frequency band can allocate the channel reserved for other (primary) users. The aim of the dissertation is to propose new methods for received signal parameter estimation (primarily the type of modulation). The influence of environment like nonlinearity, multipath propagation and low power of detected signal have to be taken into the account.
