The aims of the proposed project are to explore opportunity of detection and localization of short-circuit and micro short circuits in winding of small motors. The micro short-circuit causes the electromagnetic interferences which are transmitted to free space or is inducted into the power supply network. In the concept of detection and localization of these failures is good to take into account following approaches: antenna measurement; detection of failures in magnetic field of motor and monitoring the current distribution of tested motor in wide frequency range. Further, there is necessary to classify influence of short-circuits and micro short-circuits in wide frequency range of electromagnetic interference. More over for this type of interference detection could be used the spectral power density of interfering signal. Keep in mind, that such measurements have to be done by normally used measuring devices e.g. low cost spectrum analyser or oscilloscope. Finally, develop and introduce simple methodology for measuring and classification of short-circuit and micro short-circuit influence in small motors. Classification methodology has to be very simple to use and have to provide clear results. The simple methodology for localization of short-circuit position have to be also developed. The precision and resolution of the proposed methodology has to be at minimum for each stage of motor winding. The design and development of simple device for micro short-circuit in small motors has to be part of whole Ph. D. project.

Steadily growing number of communication devices per area and increasing quality of services require allocation of more frequency resources. Millimeter wave (MMW) frequencies between 30 and 300 GHz are very prospective for next-generation broadband cellular networks. Specific limitations of MMW signal propagation, extremely large bandwidth and time variable environment caused by mobile users connected to a backhaul networks traveling in rugged municipal environments create unprecedented challenges to the development of broadband communication systems using advanced technologies for eliminating the undesirable time varying channel features. The aim of the project is measurement and modelling of the broadband non-stationary MMW channel (between mobile users and backhaul) in time and spatial domain in order to evaluate feasibility of advanced techniques such as beamforming or massive MIMO spatial multiplexing implementation. The main goals of this topic include the effect of multipath components propagation on the time/spatial energy distribution and its statistical evaluation.

In present-day communication systems (such as digital television), the error control coding of the transmitted data is often applied independently of the source coding: parity is added to the source-coded digital signal, resulting in fixed correction capacity related to the code rate. For digital video signals such a scheme provides unchanged picture quality up to the point of exceeding the capacity of the code, where the quality drops rapidly. The aim of this project is to explore the usability of Unequal Error Protection (UEP) and Joint Source-Channel Coding (JSCC) techniques in the area of new broadcasting services (e.g., DVB-NGH) and propose optimal setup of these coding schemes for real transmission conditions. The proposed techniques should allow for graceful degradation of visual quality in degrading reception conditions, increasing the universality of systems under consideration.

Design of final applications supposes proposals of own network solutions of electronically controllable oscillators and generators of signals with specific output waveforms. One goal of this work consists in specification of parameters of active elements and blocks required for their utilization in such applications. Theoretical hypotheses will be verified by computer simulations and by experiments with commercially available elements (behavioral emulator), or eventually by simulations and realization of proposed systems in available CMOS technology (AMIS 0.35 um, TSMC 0.18 um).
