Transmitting apparatus, interleaving method thereof, receiving apparatus, and deinterleaving method thereof

摘要

A transmitting apparatus and method, and a receiving apparatus and method are provided. The transmitting apparatus includes: an encoder configured to perform encoding on data including information bits; and a bit interleaver configured to perform interleaving on the information bits and parity bits generated by the encoding, wherein the bit interleaver is configured to classify the generated parity bits into a plurality of groups and write the information bits and the generated parity bits in a plurality of columns in a column direction such that parity bits included in a predetermined group among the plurality of groups are arranged in predetermined positions in the plurality of columns, to perform the interleaving.

1. A transmitting apparatus comprising:
an encoder configured to encode information bits to generate parity bits; and a bit interleaver configured to interleave codeword bits comprising the information bits and the parity bits, wherein the bit interleaver is configured to write the codeword bits in a plurality of columns in a column direction and read the codeword bits written in the plurality of columns in a row direction, wherein the bit interleaver adjusts a starting position where the codeword bits are written on at least one of the plurality of columns such that parity bits which are disposed at predetermined intervals in the codeword bits are written on a same row in the plurality of columns, and wherein the parity bits which are disposed at predetermined intervals in the codeword bits are bits with relatively low correlation from among the parity bits in the codeword bits.
