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 6):
The BICM reception device of  claim 1 , wherein the 16 symbols are defined as shown in the following Table: TABLE W Constellation 0 0.3412 + 0.5241i 1 0.5241 + 0.3412i 2 0.5797 + 1.1282i 3 1.1282 + 0.5797i 4 \u22120.3412 + 0.5241i\u2002 5 \u22120.5241 + 0.3412i\u2002 6 \u22120.5797 + 1.1282i\u2002 7 \u22121.1282 + 0.5797i\u2002 8 0.3412 \u2212 0.5241i 9 0.5241 \u2212 0.3412i 10 0.5797 \u2212 1.1282i 11 1.1282 \u2212 0.5797i 12 \u22120.3412 \u2212 0.5241i\u2002 13 \u22120.5241 \u2212 0.3412i\u2002 14 \u22120.5797 \u2212 1.1282i\u2002 15 \u22121.1282 \u2212 0.5797i
