The diploma´s thesis is focussed on principles and characteristics of Powerline Communication. Powerline communication is a technology using powerlines for transmitting information. Its narrowband variant is developing in the field of remote data reading nowadays. There is a lot of solutions that need to be tested and simulated prior ro putting into practice. This thesis deals with preparing the OMNeT++ simulation enviroment for purposes of simulating the narrowband service PLC.

Title: Comparison of off-ice training in ice hockey in Canada and Czech republic in season. Objectives: Analyzing and comparing seletcted approaches of coaches from Canada and Czech republic. Methods: In our thesis we used a method of analysis and a method of comparison. The analysis method we used in the analysis of individual physical abilities of each period and annual training cycle and comparison method of comparing the information obtained from college internship, literature and expert consultations. Results: Based on comparison of several selected aproaches of strength and conditioning we can claim that selected strength and condtioning coaches use similar training philososphy, their work varies in mobility and endurance training and in using different modern technology. We also bulit mobility program. Keywords: ice hockey, off-ice training, comparison, strength stimulation, mobility stimulation

The master´s thesis is focussed on principles and characteristics of Powerline Communications (PLC), practical usage possibilities and advantages and disadvantage of it. There are described mudulations and a channel encoding which are in PLC used. The main part of the thesis deals with a design of a channel as transfer function through the use of two methods, an echo model and the ABCD matrix. After finishing of the design of transfer function the model of communication was created in the Matlab-Simulink program. There were used the narrowband modulations in the model and analyzed the bit error rate of the tranfer data. In the end all results were treated graphically and evaluated.
