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

FIELD: information technology.

SUBSTANCE: group of inventions refers to the field of data processing and can be used for encoding / decoding using the LDPC code. LDPC code has a code length of 16,200 bits and a code rate of 12/15. LDPC code includes an information bit and a parity bit, and the parity check matrix H is executed with the information part of the matrix, corresponding to the information bit of the LDPC code and a part of the parity matrix, corresponding to the parity bit. Informational part of the parity check matrix H is represented by a table of initial values ​​of the parity check matrix representing the position of element 1 in the informational part of the matrix with an interval of 360 columns.

EFFECT: technical result is a reduction in the error rate in data transmission.
