DEVICE AND METHOD FOR DISPLAY AND REVERSE DISPLAY OF SIGNALS IN COMMUNICATION SYSTEM USING CODE WITH LOW DENSITY OF PARITY CHECKS Russian patent published in 2019 - IPC H03M13/11 H03M13/25 H03M13/27 

FIELD: physics.

SUBSTANCE: invention relates to data transmission and is intended for display and reverse display of a signal in a system using a low-density parity check (LDPC) code. In the method, bits of the LDPC codeword are written on columns and read in rows, sub-streams are generated by demultiplexing the read bits using a demultiplexing scheme, and bits included in each sub-stream are mapped to symbols in a group of signals, wherein the demultiplexing scheme is determined in accordance with the modulation scheme used in the signal transmitter, the length of the LDPC codeword, and the number of sub-streams.

EFFECT: technical result is minimization of probability of QAM symbol errors.
