摘要： A transmitting apparatus is disclosed. The transmitting apparatus includes an encoder to perform channel encoding with respect to bits and generate a codeword, an interleaver to interleave the codeword, and a modulator to map the interleaved codeword onto a non-uniform constellation according to a modulation scheme, and the constellation may include constellation points defined based on various tables according to the modulation scheme.

摘要： A transmitting apparatus is provided. The transmitting apparatus includes: an encoder configured to perform a low-density parity check (LDPC) encoding on input bits using a parity check matrix to generate an LDPC codeword comprising information word bits and parity bits; 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 further configured to map a bit included in a predetermined bit group from among a plurality of bit groups constituting the LDPC codeword onto a predetermined bit of the modulation symbol.

摘要： A method for transmitting information is provided. The method for transmitting information comprises the steps of: mapping signalling information to one or more preamble symbols of a first frame, mapping data to one or more data symbols of the first frame, dividing additional information into two or more parts, mapping a first part of the additional information to one or more preamble symbols of the first frame, mapping a second part of the additional information to at least one of (i) one or more data symbols of the first frame, and (ii) one or more preamble symbols of a second frame and transmitting the frames.
