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 channel characteristics, a nonuniform constellation from a group of constellations comprising one or more of predetermined constellations defined by the constellation position vector u 1  . . . v, wherein v=sqrt(M)/2−1.

Claim (Index 7):
A coding and modulation method, comprising:\n encoding input data into cell words; modulating, by circuitry, the cell words into constellation points of a non-uniform constellation (NUC); and converting said constellation values into one or more data streams, wherein:\n the NUC is a Quadrature Amplitude Modulation (QAM) constellation having 1024 constellation points, each constellation point having an in-phase and a quadrature-phase component, each component having a constellation position u 0-15 =(1, 1.0005, 2.0897, 2.0888, 3.9945, 3.9931, 5.3843, 5.3894, 7.5206, 7.6013, 9.3371, 9.8429, 11.9255, 13.3962, 15.8981, 19.1591), or \u2212u 0-15 , and being associated with one of a plurality of bit labels as follows: \n 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 0 0 0 0 1 1 1 1 1 1 1 1 0 0 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 \u2212u 15 \u2212u 14 \u2212u 13 \u2212u 12 \u2212u 11 \u2212u 10 \u2212u 9 \u2212u 8 \u2212u 7 \u2212u 6 \u2212u 5 \u2212u 4 \u2212u 3 \u2212u 2 \u2212u 1 \u2212u 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 0 0 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 0 u 0 u 1 u 2 u 3 u 4 u 5 u 6 u 7 u 8 u 9 u 10 u 11 u 12 u 13 u 14 u 15
