TRANSMITTING APPARATUS AND INTERLEAVING METHOD THEREOF

摘要

A transmitting apparatus is disclosed. The transmitting apparatus comprises: an encoder generating a low-density parity check (LDPC) codeword by LDPC encoding; an interleaver interleaving the LDPC codeword; and a modulator configured to map the interleaved LDPC codeword onto a modulation symbol. The modulator can map a bit included in a predetermined bit group among the bit groups constituting the LDPC codeword onto the predetermined bit in the modulation symbol.
