Abstract

A coding and modulation apparatus and method are presented. The apparatus (10) comprises an encoder (11) that encodes input data into cell words, and a modulator (12) that modulates said cell words into constellation values of a non-uniform constellation. The modulator (12) is configured to use, based on the total number M of constellation points of the constellation, the signal-to-noise ratio SNR in dB and the number n of the dimension of the constellation, an n-dimensional non-uniform constellation from a group of constellations, wherein each constellation point of an n-dimensional constellation diagram is defined by an n-tupel of constellation values, said n-tupel of constellation values defining parameter settings of a transmission parameter used by a transmission apparatus for transmitting a transmission stream obtained by conversion of said constellation values.
