DEVICE FOR DECODING LDPC CODES Russian patent published in 2015 - IPC H03M13/00 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering and telecommunication systems. The device for decoding LDPC codes includes: a control device, first through third memory units, an arithmetic unit, first and second stacks, first through fifth counters, a first latch register, a T flip-flop, first through sixth switches, a code comparator circuit, first and second AND elements, a first adder.

EFFECT: high throughput of LDPC code device due to the exclusion of codeword symbols, reliability of which is higher than a given threshold, from LDPC code checking levels at each iteration of the decoding algorithm.
