Abstract: 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).
