Abstract
A transmitting apparatus is provided. The transmitting apparatus includes a segmenter configured to segment Layer 1 (L1) signaling; and an encoder configured to perform Low-Density Parity Check (LDPC) encoding with respect to each of the segmented L1 signalings, and the encoder punctures parity bits from LDPC parity bits added by the LDPC encoding as many as bits of a predetermined group unit.
Claims30
A transmitting apparatus comprising:
- a segmenter configured to segment Layer 1 (L1) signaling;
- and
- an encoder configured to perform Low-Density Parity-Check (LDPC) encoding with respect to each of the segmented L1 signalings,
- wherein the encoder punctures as many parity bits from LDPC parity bits added by the LDPC encoding as bits of a predetermined group unit.
A transmitting apparatus comprising:
- an encoder configured to perform Low-Density Parity-Check (LDPC) encoding with respect to Layer 1 (L1) signaling and generate an LDPC codeword;
- a bit interleaver configured to interleave the LDPC codeword on a bit basis;
- a demultiplexer configured to demultiplex the bit-interleaved LDPC codeword into a cell word;
- and
- a constellation mapper configured to map the cell word onto a constellation point.
A method for processing signals of a transmitting apparatus, the method comprising:
- segmenting Layer 1 (L1) signaling;
- and
- performing Low-Density Parity-Check (LDPC) encoding with respect to each of the segmented L1 signalings,
- wherein the performing the encoding comprises puncturing as many parity bits from LDPC parity bits added by the LDPC encoding as bits of a predetermined group unit.
A method for processing signals of a transmitting apparatus, the method comprising:
- performing Low-Density Parity-Check (LDPC) encoding with respect to Layer 1 (L1) signaling and generating an LDPC codeword;
- interleaving the LDPC codeword on a bit basis;
- demultiplexing the bit-interleaved LDPC codeword into a cell word;
- and
- mapping the cell word onto a constellation point.
A receiving apparatus which receives a signal from a transmitting apparatus and processes the signal, the receiving apparatus comprising:
- a decoder configured to perform decoding using a value corresponding to a Low-Density Parity-Check (LDPC) codeword;
- and
- a desegmenter configured to desegment segmented Layer 1 (L1) signaling which is generated by the decoding,
- wherein the decoder inserts corresponding values to bits that are punctured on a basis of a predetermined group unit by the transmitting apparatus.
A receiving apparatus which receives a signal from a transmitting apparatus and processes the signal, the receiving apparatus comprising:
- a demodulator configured to demodulate the received signal and generate a value corresponding to a Low-Density Parity-Check (LDPC) codeword;
- a multiplexer configured to multiplex the value corresponding to the LDPC codeword;
- a bit deinterleaver configured to deinterleave the value corresponding to the LDPC code word, which is multiplexed;
- and
- a decoder configured to perform decoding using the value corresponding to the LDPC codeword, which is deinterleaved.
