Abstract:
A transmitter is provided. The transmitter includes: a Low Density Parity Check (LDPC) encoder configured to encode input bits to generate an LDPC codeword including the input bits and parity bits to be transmitted in a current frame; a parity permutator configured to perform by group-wise interleaving a plurality of bit groups configuring the parity bits based on a group-wise interleaving pattern comprising a first pattern and a second pattern; a puncturer configured to puncture some of the parity-permutated parity bits; and an additional parity generator configured to select at least some of the punctured parity bits to generate additional parity bits to be transmitted in a previous frame of the current frame, based on the first pattern and the second pattern.

Claim (Index 1):
A broadcasting signal transmitting apparatus which is operable in a mode among a plurality of modes, the broadcasting signal transmitting apparatus comprising:\n an encoder configured to encode information bits comprising input bits to generate parity bits based on a low density parity check (LDPC) code having a code rate of the mode being 3/15 and a code length of the mode being 16200 bits, wherein the input bits are based on signalling information about a broadcasting data; a parity permutator configured to split a codeword into a plurality of bit groups, the codeword comprising the information bits and the parity bits, and interleave bit groups including the parity bits among the plurality of bit groups based on a permutation order of the mode, to provide an interleaved codeword; a puncturer configured to calculate a number of parity bits to be punctured based on a number of the information bits, and puncture bits of the interleaved codeword based on the calculated number; a mapper configured to map the input bits and parity bits of the interleaved codeword remaining after the puncturing onto constellation points, wherein the constellation points are generated based on a quadrature phase shift keying (QPSK) of the mode; a signal generator configured to generate a broadcast signal based on the constellation points using an orthogonal frequency division multiplexing(OFDM) scheme; and a transmitter configured to transmit the broadcast signal, wherein bits of 20 th , 24 th , 44 th , 12 th , 22 th , 40 th , 19 th , 32 th , 38 th , 41 th , 30 th , 33 th , 14 th , 28 th , 39 th  and 42 th  bit groups among the plurality of bit groups are punctured, and wherein the bit groups to be punctured are determined based on the permutation order of the mode and the calculated number.
