1. A receiving apparatus comprising:
a receiver configured to receive at least one transmission stream including symbols representative of constellation values; and
at least one processor configured to demodulate the symbols into cell words associated with Low Density Parity Check (LDPC) codewords; wherein
each of the symbols is associated with a point of a NUC, Non-Uniform Constellation,
the NUC includes sixteen points;
the NUC includes complex points defined by their real and imaginary parts as:
0.9555+j0.9555
0.9555+j0.2949
0.2949+j0.9555
0.2949+j0.2949;
and wherein a code rate of the LDPC is 12/15.
