DATA PROCESSING APPARATUS AND DATA PROCESSING METHOD Russian patent published in 2018 - IPC H03M13/19 H04L1/00 H04L27/34 

FIELD: communication.

SUBSTANCE: invention relates to communication techniques and can be used for data processing. For this, a code bit of an LDPC code in which a code length is 16200 bits and an encoding rate is 8/15 is interchanged with a symbol bit of a symbol corresponding to any of 8 signal points defined by 8PSK. When 3 bits of code bits stored in three units of storages having a storage capacity of 16200/3 bits and read bit by bit from the units of storages are allocated to one symbol, (#i + 1)-th bit from a most significant bit of the 3 bits of code bits is set to a bit b#i, (#i + 1)-th bit from a most significant bit of 3 bits of symbol bits of the one symbol is set to a bit y#i, and a bit b0 is interchanged with a bit y1, bit b1 is interchanged with a bit y0, and a bit b2 is interchanged with a bit y2.

EFFECT: technical result is to ensure a good quality of communication when transmitting data using the LDPC code.
