Abstract:
A modulator and a modulation method using a non-uniform 16-symbol signal constellation are disclosed. The modulator includes a memory and a processor. The memory receives a codeword corresponding to a low-density parity check (LDPC) code having a code rate of 4/15. The processor maps the codeword to 16 symbols of the non-uniform 16-symbol signal constellation on a 4-bit basis.

Claim (Index 3):
The BICM reception device of  claim 2 , wherein a vector corresponding to four symbols w 0 , w 1 , w 2 , and w 3  of a first group is w, a vector corresponding to four symbols w 4 , w 5 , w 6  and w 7  of a second group is \u2212conj(w) (conj(w) is a function that outputs conjugate complex numbers of all elements of w), a vector corresponding to four symbols w 12 , w 13 , w 14  and w 15  of a third group is \u2212w, and a vector corresponding to four symbols w 5 , w 9 , w 10  and w 11  of a fourth group is conj(w).
