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 1):
A BICM reception device, comprising:\n a demodulator configured to perform demodulation corresponding to 16-symbol mapping using 16 symbols of a non-uniform 16-symbol signal constellation; a bit deinterleaver configured to perform group-unit deinterleaving on interleaved values, the interleaved values generated after the demodulation; and a decoder configured to restore information bits by LDPC-decoding deinterleaved values generated based on the group-unit deinterleaving, the deinterleaved values corresponding to a LDPC codeword having a code rate of 4/15, wherein the group-unit deinterleaving is performed on a group basis, the size of the group corresponding to a parallel factor of the LDPC codeword.
