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 technology and is intended for data processing. In the data transmission device, in interchanging to interchange a code bit of an LDPC code in which a code length is 16200 bits and an encoding rate is 8/15 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, bit b0, a bit b1 and a bit b2 are interchanged with a bit y1 bit y0, and a bit y2, respectively. Position of the interchanged code bit obtained from data transmitted from the transmitting device is returned to an original position.

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