Performance Evaluation of a DVB-T2 Mobile System Using a New Time-Variant FIR-Channel

Abstract:

The second generation terrestrial digital television standard DVB-T2 was standardized in 2009. When evaluating the overall performance of such communication systems, different channel models are used to model different reception scenarios. Commonly used channel models are AWGN, Rayleigh, Ricean, and TU-6. However, since each of the models simulate a specific reception scenario, it is difficult to ascertain the realistic overall performance of the system. In this paper, we introduce a simple channel model using a time-variant FIR filter. The FIR-filtering is based on mobile field measurements obtained in Helsinki, Finland, in 2010. We apply FIR-filtering on the measurement results in order to replicate a real time-variant channel model which enables performance evaluation of the DVB-T2 system in a mobile environment. Based on the time-variant FIR-filter channel model, we simulate the performance of the DVB-T2 system, and show that there is a small performance loss when the channel conditions vary in time.
