Compared to current standards like DVB-H or DVB-SH, the largest improvement in next generation systems is expected to be achieved by means of better diversity in the time, frequency, and space domains. In this sense, DVB-NGH is the first broadcasting system to exploit the use of diversity in the three domains by incorporating at the physical layer long time interleaving (TI), time-frequency slicing (TFS), and multiple-input multiple-output (MIMO). This paper investigates the gains of using time, frequency, and space diversity in DVB-NGH, as well as the mutual influence between the different types of diversity. To this purpose, we employ an information-theoretic approach based on the outage capacity of the channel in addition to physical layer simulations.Gozálvez Serrano, D.; Gómez Barquero, D.; Vargas Paredero, DE.; Cardona Marcet, N.
