Results of the DVB-T2 Field Trial in Germany

Abstract

The second generation digital video broadcasting system for terrestrial broadcasting (DVB-T2) was designed using a toolbox concept. Compared with its predecessor DVB-T, the new standard introduces many new algorithms and allows for a more flexible parameter configuration. The parameters can be perfectly optimized for each reception scenario, ranging from stationary reception with roof-top aerials, up to portable or mobile reception. However, all countries that have already introduced DVB-T2 mainly focus on stationary reception. In contrast, stationary reception is no relevant option for a potential introduction of DVB-T2 in Germany. Instead, a potential roll-out would focus on the benefits of terrestrial broadcasting compared to satellite and cable, i.e., mobility. Within an extensive field trial in northern Germany, the performance of the different parameter configurations and new algorithms offered by DVB-T2 were analyzed in detail, e.g., multiple physical layer pipes, rotated constellations, and multiple-input single-output. This paper presents the trial network and the obtained measurement results, which are based on thousands of individual measurements. Moreover, the document gives recommendations for an optimal parameter configuration.Index Terms-Digital video broadcasting system for terrestrial broadcasting (DVB-T2), mobile reception, portable reception, field trial, terrestrial broadcasting, Doppler frequency, Bose-Chaudhuri-Hocquenghem (BCH) code packet error rate.

CNR and BER Ranges for the DVB-T2 Reception-Success

“…Improving the reception-quality can be carried-out by several schemes, such as by implementing a MISO (multiple-input single-output) technique [9] at the transmitting-side, deploying a SFN (single-frequency-network) [10], [11] or OCR (on-channel repeater) [12], [13] in the network segment, or employing a multiple-antenna (MA) method [14], [15] at the receiving-end. Several field-measurements and field-trials of DVB-T2 have also been carried-out [16]- [21]. Based on the obtained data, the required SNR threshold [19] and minimum CNR [16] are estimated, by referring to the FBER (frame block error rate) and QEF (quasi error-free) criteria, respectively.…”

Picture-Based Multiple-AntennaTechnique for the DVB-T2 Receiver

“…Several countries have adopted DVB-T2 and migrate from analog one to it. Fieldmeasurement on signal-strength distribution [3] and field-trial especially for guiding parameters setting at the transmittingside [4] have been carried out as well.…”
