Abstract:
A bit interleaver, a bit-interleaved coded modulation (BICM) device and a bit interleaving method are disclosed herein. The bit interleaver includes a first memory, a processor, and a second memory. The first memory stores a low-density parity check (LDPC) codeword having a length of 16200 and a code rate of 2/15. The processor generates an interleaved codeword by interleaving the LDPC codeword on a bit group basis. The size of the bit group corresponds to a parallel factor of the LDPC codeword. The second memory provides the interleaved codeword to a modulator for 16-symbol mapping.

Claim (Index 1):
A BICM reception device, comprising:\n a demodulator configured to perform demodulation corresponding to 16-symbol mapping; 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 length of 16200 and a code rate of 2/15, 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.
