[en] The Bit-Interleaved Coded Modulation (BICM)
block implemented in the second generation digital terrestrial television broadcasting system (DVB-T2) introduces a modified
block interleaver: the column-twist interleaver. The aim of this paper is to study how the properties, dispersion, s-parameter and memory of this interleaver are influenced by the choice of the twisting parameters. Our challenge is to put forward a set of twisting parameters that could make this interleaver more efficient, regarding the listed properties, than the ones used in
the DVB-T2 system.
