Narrow-band PLC modem
Skala, Milan ; Krajsa, Ondřej (referee) ; Mišurec, Jiří (advisor)
This bachelor's thesis deals with narrow band PLC modem for 230/400 V power line. In the first chapter we can find basic theory about using modulation, interference, impedance of line, communication, capacitive and inductive coupler. Next chapter deals with design and simulation of capacitive coupler, transceiver circuit, receiver circuit, power supply and circuit for modem synchronization with power line frequency. In this chapter we can find information about building a converter from UART to USB. Third chapter of this thesis is dedicated to designing the printed circuit board and building the modem. Last chapter deals with setting the modem switches, description of its inputs and outputs and basic manual for the modem's software.

Analysis and modeling of Power Line Communication
Mlýnek, Petr ; Orgoň, Miloš (referee) ; Pospíchal, Ladislav (referee) ; Mišurec, Jiří (advisor)
The dissertation thesis focuses on the analysis and modelling of power line communication. In first part of the thesis, a basic information of power line communication are described, primarily principle, advantage and disadvantage. The physical layer of the transmission and the fundament of modelling are described later. In the following section the objectives of the dissertation thesis are specified. Experimental verification of the created models and creating of indoor and outdoor models are one of the major goals of this work. These models approximate the real parameters of the power lines communication with sufficient precision. A detailed analysis of existing and current research in power line communication modeling, especially for the power line models, then follows. Based on this analysis a mathematical description of the models is specified and reference model for different scenarios is designed. The communication channel model, power line model and noise model are designed in own solution part. In this part the main goals, experimental verification of created models and designed of models for indoor and outdoor line were also realized. By merging of individual models, PLC communication system model with all parameters analyzed in detail arise. The analyzed parameters which were previously published, do not contain these parameters coherently. The last part of the thesis gives a summary of the results of these analyzes and discussion of simulation results.

The Models of Power Lines for PLC Data Communication Systems
Fajkus, Petr ; Mišurec, Jiří (referee) ; Lázničková, Ilona (advisor)
Bachelor's thesis is focused on the issue of data communications over power lines. This technology is known as PLC (Power Line Communication). Wider deployment of this technology into practice at present prevents a number of shortcomings. Main problems are disturbance useful signal on power lines, radiation interference, small reach of useful signal and elements of energy network, which affect the transmission. In the analysis of sub-problems, it appears that it is appropriate to have a computer power line model, allowing a computer simulation of data communication over power line. It is necessary to combine two different, conflicting requirements. Power lines are not primarily intended for data communication, and data lines are not designed for the transmission of electricity. Both types of line are described the same primary parameters, but they operate in completely different modes. This thesis examines these modes and possible models of power and data lines in terms of data communication. The main part is devoted to the draft power line model for data communication and computer verification of the functionality of the new proposed model.
