The BICM reception device includes a demodulator, a bit deinterleaver, and a decoder. The demodulator performs demodulation corresponding to 1024-symbol mapping. The bit deinterleaver performs group-unit deinterleaving on interleaved values. The interleaved values are generated after the demodulation. The decoder restores information bits by LDPC-decoding deinterleaved values generated based on the group-unit deinterleaving. The deinterleaved values corresponds to a LDPC codeword having a length of 64800 and a code rate of 2/15."},"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 2/15 and 1024-symbol mapping, and bit interleaving method using same","description":"A bit-interleaved coded modulation (BICM) reception device and a BICM reception method are disclosed herein.
