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 and the code rate, a non-uniform constellation from one or several groups of constellations each comprising one or more constellations.

Claim (Index 6):
A coding and modulation apparatus, comprising:\n encoder circuitry configured to encode input data into cell words; and modulator circuitry configured to modulate said cell words into constellation values of a non-uniform constellation, wherein the modulator circuitry uses the following quarter of a non-uniform constellation having a total number of M=64 constellation points and the code rate 8/15, the constellation points are defined by a constellation position vector W 0 . . . b-1  with b=M/4 w0 0.2920 + 1.4827i w1 0.8411 + 1.2563i w2 0.2174 + 1.0211i w3 0.5702 + 0.8798i w4 1.4827 + 0.2920i w5 1.2563 + 0.8410i w6 1.0211 + 0.2174i w7 0.8798 + 0.5702i w8 0.1475 + 0.3040i w9 0.1691 + 0.3028i w10 0.1871 + 0.6855i w11 0.3563 + 0.6126i w12 0.3040 + 0.1475i w13 0.3028 + 0.1691i w14 0.6855 + 0.1871i w15 0.6126 + 0.3563i and the other three quarters are derived by symmetry from the said quarter of a non-uniform constellation and wherein the bit positions of the non-uniform constellation are interchanged.
