DATA PROCESSING APPARATUS AND DATA PROCESSING METHOD Russian patent published in 2016 - IPC H03M13/19 G06F11/10 

FIELD: data processing.

SUBSTANCE: invention relates to data processing device and method of data processing. For this purpose, when LDPC code (low density parity check), having length of 16,200 code bits and coding rate of 8/15, displayed on 16 signal points, if (#i+1)st of most significant bits significant bits symbol bits for 4×2 bits and symbol bits for 4×2 bits from two successive symbols set of bits b#i and y#i accordingly, demultiplexer performs mutual replacement for extraction b0, b1, b2, b3, b4, b5, b6 and b7 for y0, y4, y3, y1, y2, y5, y6 and y7, respectively. This technology may be used in transmitting system, etc., which transmits LDPC code.

EFFECT: technical result is increase of data stability to error.
