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 64800 and a code rate of 3/15. 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 256-symbol mapping."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Bit interleaver for low-density parity check codeword having length of 64800 and code rate of 3/15 and 256-symbol mapping, and bit interleaving method using same","description":"A bit interleaver, a bit-interleaved coded modulation (BICM) device and a bit interleaving method are disclosed herein.
