Vectoring in xDSL systems
Rada, Dominik ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
This bachelor's thesis presents the approximation of VDSL2 and G.fast transmission systems according to pre-selected cable types. The thesis is also focused on the principle of vectoring and its use. The components of the thesis are explained by initialization process in modems with support of vectoring and approximation of Pre-Coder algorithms. A part of the thesis is a created user application in MATLAB, which displays the influence of vectoring on the transfer rates based on user input. In addition, the application captures primary and secondary line parameters, transmission characteristics, and transmitted masks.

Power line parameters
Kavan, Pavel ; Krajsa, Ondřej (referee) ; Mlýnek, Petr (advisor)
At the beginning is diploma thesis focused on a distribute power line parameters measurement and examination changes of this parameters depending on using of various power line cables. On the basis of measurements is made a transmission channel in Matlab & Simulink, where are executed simulations with power transmission line. The simulated power line is based on measured distribute parameters or physical proportions of cabels. By changing different parts of simulated communication channel is a symbol error rate expressed on the lenght of transmission line.
