Measurement of the DVB-T2-based MISO Signal influenced by I/Q-errors in the OFDM Modulator
 Buchta, Simon ; Polák, Ladislav
The Second Generation Digital Video Broadcasting Terrestrial (DVB-T2) system stands out as the most advanced system among the second generation DVB standards. Among others, it supports the multiple-input single-output (MISO) transmission technique to enhance terrestrial TV broadcasting. This paper focuses on a performance study of the DVB-T2 system utilizing the MISO technique for various fixed transmission scenarios, which are modeled by different transmission channel models. Additionally, it considers imperfections of the transmitter, due to errors in the Orthogonal Frequency-Division Multiplexing (OFDM) modulator. To facilitate this study, a laboratory measurement workstation with an appropriate measurement methodology is established. The proposed concept enables the interchangeability of measurement equipment and set-top-boxes (STBs).

Laboratory workplace for measurement of DVB-T2 MISO broadcasting
 Bárta, Vojtěch ; Kratochvíl, Tomáš (referee) ; Polák, Ladislav (advisor)
This bachelor thesis deals with measurement and analysis of DVB-T2 MISO broadcasts. The theoretical part of the thesis describes the broadcasting chain of the DVB-T2 system at the level of the physical layers. Attention is paid to both SISO and MISO transmit modes. In the experimental part of the work is to design a measuring workplace for monitoring and analysis of DVB-T2 MISO transmission in laboratory conditions. The functionality of the proposed concept and chosen measuring methodology was verified by a set of experimental measurements.
