Localization system making use of GPS and GSM
Klozar, Lukáš ; Pust, Radim (referee) ; Šebela, Radek (advisor)
Aim of this master´s project is to analyse localization possibilities in GSM and GPS wireless networks. Choise of proper module and design location device for both GPS and GSM networks. Design and construction of system, which is able to designate it´s positron, using both GPS and GSM networks. The location informations, are send to Internet server, using GPRS system. Localization techniques in both wireless network are described. The system which is able to get position information was designed and constructed. The module´s driving software and the software, which process the localization informations and controls the database storing process, was designed.

Modelling and simulation of communication system receiver for unmanned aircraft
Hoferek, Jakub ; Prokeš, Aleš (referee) ; Maršálek, Roman (advisor)
This diploma thesis deals with the simulation of the radio communication system for satellite control of unmanned aircraft, namely the command and control communication link – the forward link. The aim of the thesis is to create a simulator in the Matlab environment. The simulator includes a model of the transmitter, radio channel and receiver. Four-state CPM modulation with partial response and filtered symbol shape is used. The radio channel performs noise, frequency Doppler shift and time delay to the received signal. Subsequently, in the Acquisition Unit, the Doppler shift and time delay are detected and compensated. At the end of the thesis, the simulation results of the presented model are presented in the form of graphs đť¸s/đť‘0.
