Abstract
A transmitter apparatus and a receiver apparatus are provided. The transmitter apparatus includes: an encoder configured to generate a low density parity check (LDPC) by performing LDPC encoding; an interleaver configured to interleave the LDPC codeword; and a modulator configured to map the interleaved LDPC codeword onto a modulation symbol. The modulator maps a bit included in a predetermined group from among a plurality of groups constituting the LDPC codeword onto a predetermined bit in the modulation symbol.
Claims5
A transmitter comprising:
- a Low Density Parity Check (LDPC) encoder configured to encode input bits to generate parity bits;
- an interleaver configured to interleave an LDPC codeword comprising the input bits and the parity bits;
- and
- a mapper configured to map the interleaved LDPC codeword onto a plurality of constellation points,
- wherein the interleaver comprises:
- a parity interleaver configured to interleave the parity bits;
- a group-wise interleaver configured to interleave a plurality of bit groups constituting the parity interleaved LDPC codeword;
- and
- a block interleaver configured to interleave the group-wise interleaved LDPC codeword.
