DVB-T2 Thresholds for Portable Indoor Reception Scenarios Respecting IQ-Errors

Popis výsledku v původním jazyce

The second generation digital terrestrial video broadcasting system (DVB-T2), compared to its predecessor, has extended options of system configurations to broadcast TV services for different transmission scenarios. This paper, according to the report ITU-R BT.2254-2, presents minimal carrier-to-noise (C/N) values for the correct reception of DVB-T2 signal, fulfilling quasi-error-free (QEF) condition, under portable indoor reception scenarios. The influence of different code rates (CRs), M-QAM modulations, guard interval (GI) lengths and pilot patterns (PPs) on the DVB-T2 performance is studied. In addition, this study takes into account In-phase and Quadrature (IQ) errors, which can occur in the Orthogonal Frequency Division Multiplexing (OFDM) modulator. All the theory-based results are confirmed by extensive laboratory measurements. The obtained results extend the ITU-R BT.224-2 report with a new set of C/N values for DVB-T2 signals under different portable indoor reception scenarios, which can be used by the broadcasters for DVB-T2 network planning.
