Optical infrastructures of 5th generation mobile networks (5G)
Jančošek, Matúš ; Münster, Petr (referee) ; Látal, Michal (advisor)
The bachelor thesis deals with the analysis of the current state of optical networks used in telecommunications. There is an analysis of the current state of optical networks and a comparison of the last two generations of mobile networks. The main part of the work is the simulation of optical transmission. Three different types of modulations are compared, three different types of optical fibers according to the ITU-T type and four different wavelengths, which present standard and non-standard wavelengths. The second simulation is a comparison of modulations and the effect of distance on bit error rate. The results of the analyses are presented in the tables.

Analysis of the transmission in the mobile digital audio broadcasting
Kresta, Daniel ; Ulovec,, Karel (referee) ; Kratochvíl, Tomáš (advisor)
This thesis deals with an analysis of a system called Digital Audio Broadcast and describes its mathematical model created in MATLAB program. In the first part basic blocks of a transmitter and a receiver are analyzed along with their principles. Then different types of transmission channels for static, portable and mobile receivers are described. The second part contains description of the DAB mathematical model itself. Individual blocks are described in the order of the DAB signal path, from the transmitter through the transmission channel to the receiver side. In this part the graphical user interface is also described. In the final part the results of experimental measurements and simulations are presented.
