Orthogonal Frequency Division Multiplex
Spurný, Jan ; Maršálek, Roman (referee) ; Hanus, Stanislav (advisor)
OFDM is now days very important and widely used modulation technology, which allows high transmission speeds and is able to be used within radio communication channels. The aim of this bachelor`s project is to gain understanding of OFDM modulation, and an analysis of the processing signals, which are used. And finally, form a block diagram of modulator and demodulator in MATLAB environment, which allows observing signal in time and frequency domain.

G.fast transmission technology
Zvařič, Filip ; Číž, Radim (referee) ; Šilhavý, Pavel (advisor)
This diploma thesis focuses on G.fast and VDSL2 technologies and their comparison. G.fast has the prerequisites for replacing VDSL2 for short distances. This work describes in detail the modulation techniques of both DSL technologies - DMT modulation used by both technologies. The aim of this work is to create a software for comparing the transfer rates of all profiles of both technologies, including the effects of far-end crosstalk. This is performed in the Matlab environment. This work describes how the program works and how to run the simulations. The results of selected simulations and their charts are enclosed in this work.
