1. A transmitter apparatus comprising:
- an encoder configured to generate a low density parity check (LDPC) codeword 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,wherein the modulator is configured to map 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.

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.
