Simulation of multipah propagation of multistate modulations
Polák, Ladislav ; Pust, Radim (referee) ; Šebela, Radek (advisor)
The diploma thesis Simulation of Multipath Propagation of Multistate Modulations is focused on the development of an appropriate algorithm in MATLAB environment, which is capable to simulate the impact of the multipath propagation on received signal (error rate) on the basis of given parameters of the transmission channels. Mechanisms and characteristics of the wave propagation in communication environment, types of digital modulations and their most important parameters are described in the first part of this thesis. The second part is focused on the simulation itself. Created GUI (Graphical User Interface) is able to display constellation diagrams of transmitted and received signals, as well as their bit error rate. It is also possible to compare these data with the data of signal, which is passed by a non-fading channel.

Analysis of digital modulation robustness at various types of interference
Uher, Tomáš ; Šilhavý, Pavel (referee) ; Kubánková, Anna (advisor)
This bachelor thesis concisely describes essential type of modulation technique for transmission of binary signal. In first part there are summarized advantages and disadvantages for each described modulation technique. There are described proceeding of modulation and demodulation too. Selected digital modulations are tested for Gaussian, Rice and Rayleigh transmission channels. In final part there are compared theoretical and measured values and summarized analysis.
