An apparatus includes an encoder configured to encode source data and generate a codeword composed of a plurality of bits, and an interleaver configured to perform, on the codeword, block-based interleaving including a plurality of sub-blocks, wherein the interleaver is configured to generate a first reference input index of a first reference sub-block from among the sub-blocks, generate, based on the first reference input index, a first input index of a first sub-block from among the sub-blocks, the first sub-block being arranged to be adjacent to the first reference sub-block in a first direction, and store, in an internal memory, bits corresponding to the first reference sub-block and the first sub-block, according to the first reference input index and the first input index, respectively.

Method and apparatus for performing block interleaving for data transmission

The present disclosure relates to a decoding method. The decoding method includes a sequentially determining series of source bits from a codeword by performing a first decoding operation and a second decoding operation. For instance, a series of N source bits may be divided into a first bit group of X source bits and a second bit group of Y source bits. The initial X source bits are sequentially determined in the first decoding operation and the remaining Y source bits are sequentially determined in the second decoding operation. The first decoding operation includes sorting at least 2L reliability values, which are calculated from L bit sequences, where L is an integer greater than 0. The second decoding operation includes determining a source bit in each of the L bit sequences, based on the at least 2L reliability values.
