DATA PROCESSING APPARATUS AND DATA PROCESSING METHOD Russian patent published in 2018 - IPC H03M13/11 H03M13/25 H03M13/27 

FIELD: general-purpose electronic circuits.

SUBSTANCE: group of inventions relates to the field of data processing and can be used for encoding / decoding using an LDPC code. LDPC code contains information bits and parity bits. Parity check matrix includes an information matrix section corresponding to the information bits, and a parity matrix section corresponding to the parity bits. Information matrix section is represented by a check matrix initial value table. Parity check matrix initial value table is a table which shows the position of 1 elements of the information matrix section for each of 360 rows.

EFFECT: technical result is high resistance of the LDPC code to errors.
