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 10-bit cell words and to decode the 10-bit cell words into output data words representing Forward Error Correction (FEC) data words, wherein each 10-bit cell word is associated with a point of a Non-Uniform Constellation (NUC),
wherein each point (Zq) of the NUC has an in-phase component Re(Zq) and a quadrature component Im(Zq),
wherein the in-phase component Re(Zq) corresponds to a constellation position of a first vector (u0, u1, u2, u3, u4, u5, u6, u7, u8, u9, u10, u11, u12, u13, u14, u15),
wherein the quadrature component Im(Zq) corresponds to a constellation position of the first vector (u0, u1, u2, u3, u4, u5, u6, u7, u8, u9, u10, u11, u12, u13, u14, u15), and
wherein the first vector (u0, u1, u2, u3, u4, u5, u6, u7, u8, u9, u10, u11, u12, u13, u14, u15) corresponds to a vector defined as (1, 2.5983, 4.5193, 6.1649, 8.2107, 9.9594, 12.0321, 13.9574, 16.2598, 18.4269, 20.9273, 23.4863, 26.4823, 29.7085, 33.6247, 38.5854).
