VSAT Terminal Model
Kudlička, Miroslav ; Ondráš, Radek (referee) ; Baran, Ondřej (advisor)
This work deals with the description of the communication using the VSAT satellite network. A used network topology, frequency bands, satellite orbits and also an access technology are defined. The next part is focused on the VSAT terminal, where the block diagram is shown. A model of the indoor unit IDU is designed in the system background of Ansoft Designer. Individual parts of the system model are analyzed in terms of input variables. The results of the simulation are shown. The curves of BER before Viterbi decoding and after Viterbi decoding are shown too.

Broadband Amplifier for the Counter
Kudlička, Miroslav ; Frýza, Tomáš (referee) ; Říčný, Václav (advisor)
This work deals with possibilities design of broadband amplifier fit for the counter LCK-1. There are described three methods for possibilities solvings. The method by discretes of parts with stagger-tuned circuits, the method by operational amplifier THS3201 and the method by monolitic amplifier ERA-3. The Method by operational amplifier THS3201 is chosen like the best method, because this operational amplifier can amplify very small signals. There is designed of amplifier THS3201 in the simulation software PSpice and this results are take into account for realization broadband amplifier.
