Learning LDPC codes with quantized density evolution over relaxed protographs
Gennady Shutkov, Dmitry Artemasov, Alexey Frolov +2
We consider the design of low-density parity-check (LDPC) codes for a given iterative decoder. Despite tools such as direct simulation, density evolution (DE), and EXIT-chart analy…

Iterative Neural Rollback Chase-Pyndiah Decoding
Dmitry Artemasov, Oleg Nesterenkov, Kirill Andreev +2
Iterative decoding is essential in modern communication systems, especially optical communications, where error-correcting codes such as turbo product codes (TPC) and staircase cod…

Generalized LDPC codes with low-complexity decoding and fast convergence
Dawit Simegn, Dmitry Artemasov, Kirill Andreev +2
We consider generalized low-density parity-check (GLDPC) codes with component codes that are duals of Cordaro-Wagner codes. Two efficient decoding algorithms are proposed: one base…
