This paper describes the main features of the DVB-NGH Bit-Interleaved Coded Modulation (BICM) module. This latter is derived from a sub-set of DVB-T2 BICM components with additional features intended to first lower receiver complexity and power consumption and then to increase receiver robustness over mobile reception. Therefore, the long code block size was removed, a different range of coding rates was chosen, non-uniform constellations were adopted in order to provide shaping gain, and the principle of signal space diversity was extended to four-dimensional rotated constellations. Moreover the structure of the time interleaver offers the possibility to significantly increase the interleaving depth, a feature required for mobility over terrestrial and satellite links.
