Abstract:
1. An encoding apparatus comprising: a modulation rule applying section modulating user data into a data code sequence formed of logic 1 and logic 0 according to a predetermined rule, and obtaining modulation-rule-applied encoded sequence data; an interleave section interleaving the modulation-rule-applied encoded sequence data, and obtaining interleaved sequence data; an LDPC parity generating section subjecting the interleaved sequence data to low density parity check (LDPC) encoding processing, and obtaining LDPC parity sequence data; an inserting section configured to receive the modulation-rule-applied encoded sequence data and the LDPC parity sequence data, and insert species of the LDPC parity sequence data in the modulation-rule-applied encoded sequence data in a predetermined distributed manner, and obtaining output data; and an output section transmitting the output data.
