TRANSMITTER APPARATUS AND SIGNAL PROCESSING METHOD THEREOF |
摘要 |
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. |

1. An interleaving method of a transmitter, the interleaving method comprising:
encoding input bits to generate parity bits; interleaving a Low Density Parity Check (LDPC) codeword comprising the input bits and the parity bits; and mapping the interleaved LDPC codeword onto a plurality of constellation points, wherein the interleaving comprises: interleaving the parity bits; splitting the interleaved LDPC codeword comprising the input bits and the interleaved parity bits into a plurality of bit groups; interleaving the plurality of bit groups; and interleaving the interleaved plurality of bit groups. |
