    摘要： A signal transmission apparatus in a communication system is disclosed. A channel interleaver generates an interleaved vector by channel-interleaving a Low Density Parity Check (LDPC) codeword according to a channel interleaving rule, and a modulator generates a modulation symbol by modulating the interleaved vector according to a modulation scheme. The channel interleaving rule is one of a first channel interleaving rule and a second channel interleaving rule. The first channel interleaving rule is a rule for setting degree distribution for nodes in a factor graph of the LDPC codeword separately for individual levels supported by the modulation scheme. The second channel interleaving rule is a rule for allowing coded bits included in the LDPC codeword to be interleaved according to an unequal error characteristic of the modulation scheme.

    摘要： A signal reception apparatus for a communication system is disclosed in which the signal reception apparatus receives a signal and decodes the received signal using a second decoding scheme approximated from a first decoding scheme. The second decoding scheme is a scheme of applying a correction value to a third decoding scheme approximated from the first decoding scheme, and the correction value is a value for correcting a difference between a first signal obtained by decoding the received signal using the first decoding scheme and a second signal obtained by decoding the received signal using the third decoding scheme.
