MODULATOR AND MODULATION METHOD USING NON-UNIFORM 16-SYMBOL SIGNAL CONSTELLATION FOR LOW-DENSITY PARITY CHECK CODEWORD HAVING 3/15 CODE RATE |
| 摘要 |
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 3/15. The processor maps the codeword to 16 symbols of the non-uniform 16-symbol signal constellation on a 4-bit basis. |

1. A modulation method using a non-uniform 16-symbol signal constellation, comprising:
receiving a codeword corresponding to a low-density parity check (LDPC) code having a code rate of 3/15; and mapping the codeword to 16 symbols of the non-uniform 16-symbol signal constellation on a 4-bit basis. |
