Programme for channel coding demonstration
Závorka, Radek ; Vařacha, František (referee) ; Prokeš, Aleš (advisor)
The main subject of this thesis is creating a programme, used for channel coding demonstration. This programme will be used for teaching purposes. The programme contains various codes from simple ones, to those which almost reach Shanon’s channel capacity theorem. Specifically these are the Hamming code, cyclic code, convolutional code and LDPC code. These functions are based on theoretical background described in this thesis and have been programed in Matlab. Practical output of this thesis is user interface, where the user is able to input information word, simulate transmission through the transmission channel and observe coding and decoding for each code. This thesis also contains a comparison between individual codes, concerning bit-error rate depending on SNR and various parameters. There is a computer lab with theoretical background, assignment and sheets for convenient accomplishment of each task.

Temperature measurements with PT100 for aerospace applications
Závorka, Radek ; Dobesch, Aleš (referee) ; Kolka, Zdeněk (advisor)
This bachelor thesis deals with design of temperature measurement system, which is focused on aviation applications. The design emphasizes fulfilment of aviation standards, especially protection against voltage needle pulses and transient phenomena caused by lightning. Device must be resistant against electromagnetic interference. The core of equipment is AD converter with current source from Texas Instruments, which is suitable for connect different type of sensors. The whole system is controlled by microcontroller from ARM series. The measurement values are display on monitor of computer, which is connect by serial line.

Measurement-Based 60 Ghz Tapped-Delay-Line Channel Model
Zavorka, Radek
With the development of communication technology a new electromagnetic spectrum isnecessary. It is the reason for the research of millimeter waves (MMW) about 60 GHz. This paper isfocused on the evaluation impact of multipath components on receive signals. It depends on the radiationpattern of used antennas and the direction of the receiving antenna related to the line of sight (LOS)component. The multipath components (MPCs) are received from surrounding points around the centerof the transmitter. To model the MPCs propagation a basic Tap Delay Line (TDL) model is establishedincluding individual tap indexes and important points are compared mutually. Research is alsofocused on the determination of the reflectivity of the surrounding objects.
