    Abstract: A transmitter is provided. The transmitter includes: an outer encoder configured to encode input bits to generate outer-encoded bits including the input bits and parity bits; a zero padder configured to generate a plurality of bit groups each of which is formed of a same number of bits, maps the outer-encoded bits to some of the bits in the bit groups, and pads zero bits to remaining bits in the bit groups, based on a predetermined shortening pattern, thereby to constitute Low Density Parity Check (LDPC) information bits; and an LDPC encoder configured to encode the LDPC information bits, wherein the remaining bits in which zero bits are padded include some of the bit groups which are not sequentially disposed in the LDPC information bits.

    Abstract: A transmitting apparatus and a receiving apparatus are provided. The transmitting apparatus includes 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 modulate the interleaved LDPC codeword according to a modulation method to generate a modulation symbol. The interleaver performs interleaving by dividing the LDPC codeword into a plurality of groups, rearranging an order of the plurality of groups in group units, and dividing the plurality of rearranged groups based on a modulation order according to the modulation method.

    Abstract: A transmitter is provided. The transmitter includes: a Low Density Parity Check (LDPC) encoder which encodes input bits including outer encoded bits to generate an LDPC codeword including the input bits and parity bits to be transmitted to a receiver in a current frame; a puncturer which punctures a part of the parity bits which is not transmitted in the current frame; and an additional parity generator which selects at least a part of the parity bits to generate additional parity bits transmitted to the receiver in a previous frame of the current frame, wherein a number of the additional parity bits is determined based on a number of the outer encoded bits and a number of the parity bits left after the puncturing.

    Abstract: A transmitter is provided. The transmitter includes: an outer encoder configured to encode input bits to generate outer-encoded bits including the input bits and parity bits; a zero padder configured to generate a plurality of bit groups each of which is formed of a same number of bits, determine whether a number of the outer-encoded bits satisfies a predetermined number of bits required according to at least one of a code rate and a code length for Low Density Parity Check (LDPC) encoding, pads zero bits to some of the bits in the bit groups if the number of the outer-encoded bits is less than the predetermined number of bits, and maps the outer-encoded bits to remaining bits in the bit groups, based on a predetermined shortening pattern, thereby to constitute LDPC information bits; and an LDPC encoder configured to encode the LDPC information bits, wherein the some of the bits, in which zero bits are padded, are included in some of the bit groups which are not sequentially disposed in the LDPC information bits.

    Abstract: Provided is a signal interleaving method which includes: interleaving parity bits by encoding input bits based on a low density parity check (LDPC) code according to a code rate of 6/15 and a code length of 64800; splitting a codeword comprising the input bits and the interleaved parity bits into a plurality of bit groups; interleaving the plurality of bit groups according to a specific permutation order to provide an interleaved codeword; de-multiplexing bits of the interleaved codeword to generate data cells; mapping the data cells onto constellation points for 1024-quadrature amplitude modulation (QAM); and transmitting a signal based on the constellation points.
