Abstract
A coding and modulation apparatus and method are presented. The apparatus () comprises an encoder () that encodes input data into cell words, and a modulator () that modulates said cell words into constellation values of a non-uniform constellation. The modulator () 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 channel characteristics, a non-uniform constellation from a group of constellations comprising one or more of predetermined constellations defined by the constellation position vector u1 . . . v, wherein v=sqrt(M)/2−1.
