TRANSMITTING APPARATUS AND INTERLEAVING METHOD THEREOF |
| 摘要 |
A transmitting apparatus is provided. The transmitting apparatus includes: an encoder configured to generate a low density parity check (LDPC) codeword by LDPC encoding based on a parity check matrix; 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. |

1. A transmitting apparatus comprising:
a Low Density Parity Check (LDPC) encoder configured to encode input bits to generate parity bits according to a code rate of 5/15 and a code length of 16200; an interleaver configured to interleave an LDPC codeword comprising the input bits and the parity bits; and a mapper configured to map the interleaved LDPC codeword onto constellation points for QPSK, wherein the interleaver is configured to group-wise interleave a plurality of bit groups constituting the LDPC codeword using the following equation:
Yj=Xπ(j)(0≦j<Ngroup), where Xj is a jth bit group among the plurality of bit groups, Yj is a interleaved jth bit group, Ngroup is a total number of the plurality of bit groups, and π(j) denotes a permutation order for group wise interleaving, and wherein the π(j) is defined as the table below;CodeOrder of group-wise interleavingRateπ(j) (0 ≦ j < 45)5/150123456789101112131415161718192021222324252627282930313233343536373839404142434435729111432382820172539194112103004443221513343723153618421633312722364024419268. |
