Measurement and analysis of the DAB system
Kaštánek, Petr ; Kufa, Jan (referee) ; Polák, Ladislav (advisor)
This thesis deals with the measurement and analysis the performance of the Digital Audio Broadcasting (DAB) system. Theoretical part of the work contains a brief description of the signal processing chain of DAB. Attention is devoted to physical layer (PHY). In the experimental part of the work is designed and implemented laboratory measuring workplace for reception, processing and evaluation of DAB signal. The RTL2832U software defined radio (SDR) is used as a receiver of the DAB signal. The functionality of the proposed concept is verified by a detailed measurement.

Software for the analysis of the remote-reading of the meters
Přívětivý, Radek ; Tříska, Martin (referee) ; Mego, Roman (advisor)
There are describes the principles of remote meter reading in the home and components of smart grids for reading these meters in the first part of master’s thesis. The next part of the thesis contains description of standard Wireless M-Bus and ZigBee. The next chapter is description of the circuit Realtek RTL2832U, which is part of the selected tuner. Another part is devoted to basic description of modulation focusing on the angle modulation – FM, FSK. In the final part is a detailed description of the received signal. AES encryption and created software.

Laboratory Workplace For Performance Measurement Of The Dab/Dab+ System
Kaštánek, Petr
In this paper, a simple laboratory measurement workplace, proposed for educational purposes, to measure the performance of the DAB/DAB+ signal is presented. The RTL2832U software defined radio (SDR) is used as a receiver of the DAB signal in the measurement setup. Freeware available program DAB Player is used to analyze the DAB signal on the objective and subjective level. The functionality of the proposed concept as well as the applied measurement methodology is verified by simple experimental measurements.
