Issued topics of Doctoral Study Program
The aim of the project is in the solutions of amplifiers or multipliers in advanced classes E, F, G and other in the microwave band. These classes allow improving various parameters of standard circuits, such as efficiency, intermodulation level and others, depending on specific application. The change of parameters is done with the use of manipulation of harmonic frequencies of input signal. In the work it will be necessary to simulate those circuits, to realize selected designs and select proper methodology of measurements in the case of designed circuits.

Requirement of effective utilization of radio frequency (RF) channels fed to the development of cognitive radio (CR), which can allocate free frequency bands, detect the parameters of transmitted signals in the occupied bands, etc. The CR can then be reconfigured (change the transfer protocol, modulation, bandwidth, etc.) in order to share RF spectrum without harmful interference with other users. The aim of the project is analysis and development of reliable and efficient spectrum sensing algorithms. The project will be dominantly focused on comparison and improvement of the known spectrum sensing methods typical for the non-cooperative systems (energy detection, cyclostationary detection, matched filter detection, etc) and on their optimization and combination for specific applications (mobile communications, sensor networks, etc). Some sensing techniques suitable for cooperative systems can also be investigated.

The project is focused on the analysis of non-standard electromagnetic environments for electromagnetic interference measurements. The analysis has to be focused on different measurement techniques and also some calibrations of the unknown environment. The main aim is to gain similar result of measurements in the uncertain condition as in the semi-anechoic chambers by special measurement setups and corrections. The analysis has to cover also full and semi-anechoic chambers and also reverberations and only shielded rooms.

Cross-Layer Optimization is different approach for communication than OSI model. Because of feedback between layer interface is possible to adjust system parameters for compensation of the actual channel conditions. These adjustment leads to eliminate outage of connection or packet loss. The goal of the project is to enhance state-of-the-art simulation tools for adaptation of performance due to channel conditions. The application part is transmission of the streamed video in LTE and LTE-A systems with adaptation of the source coder based on video quality evaluation and channel conditions.

A present day high-speed wireless communication systems are based on optical and microwave frequency bands usage. Their reliability and availability are largely affected by atmospheric conditions (rain, snow fall and fog). Due to the difference of the wavelength used, the combination of both the systems offers very reliable communication tool, because more reliable transmission channel can be chosen according to the atmospheric conditions. The aim of the project is investigation and modeling of the transmission channel in view of both the systems, determination of the link availability and transmission capacity of combined link and finding algorithms for an optimal allocation of data flow. A number of measurements on real communication systems and statistical evaluation of measured data will be included in the project.

Within the scope of thesis, student will analyze the modern algorithms in processing chain from the single/multi picture capturing, up to picture interpretation (classic view, 3-D TV, free-point view). The aim of several systems is the real-time processing; therefore, the knowledge of highly time consuming parts of algorithms, or potential bottlenecks is significant. The real-time processing can be achieved also by heterogeneous systems (i.e. by combination of CPUs, GPUs, DSPs) with high level of parallelization. The result of thesis should be the optimized model of fundamental blocks of compression chain on specific hardware multi-cores platform as well. Remark: Topic cooperates with the project of Simula Research Laboratory (Oslo, Norway) for image processing of the football match.

Ultra wide-band (UWB) technology is considered to be a suitable candidate for many applications in area of data transmission or positioning due to its wideband nature. Utilization of this technology requires the knowledge of the specific channel properties in frequency band from 3.1 GHz to 10.6 GHz. The aim of the project is research of the UWB channel properties and creation of UWB channel models for specific applications in area of positioning and data transmission in outdoor and indoor environments and in vehicle interiors. Utilization of these models is assumed for applications of sensor networks in vehicles, for WPAN multimedia communications, positioning of the cars in a parking lot, or for application of the car to car communication (Car-2-Car technology).
