Check-Belief Propagation Decoding of LDPC Codes [PDF]

IEEE Transactions on Communications, 2023
Variant belief propagation (BP) algorithms are applied to low-density parity-check (LDPC) codes. However, conventional decoders suffer from a large resource consumption due to gathering messages from all the neighbour variable-nodes and/or check-nodes through cumulative calculations. In this paper, a check-belief propagation (CBP) decoding algorithm is

Exploiting degeneracy in belief propagation decoding of quantum codes [PDF]

npj Quantum Information, 2022
Quantum information needs to be protected by quantum error-correcting codes due to imperfect physical devices and operations. One would like to have an efficient and high-performance decoding procedure for the class of quantum stabilizer codes.

Efficient Decoding of Turbo Codes with Nonbinary Belief Propagation [PDF]

EURASIP Journal on Wireless Communications and Networking, 2008
This paper presents a new approach to decode turbo codes using a nonbinary belief propagation decoder. The proposed approach can be decomposed into two main steps.

Adaptive Learned Belief Propagation for Decoding Error-Correcting Codes [PDF]

Entropy
Weighted belief propagation (WBP) for the decoding of linear block codes is considered. In WBP, the Tanner graph of the code is unrolled with respect to the iterations of the belief propagation decoder.

Branch-Assisted Sign-Flipping Belief Propagation Decoding for Topological Quantum Codes Based on Hypergraph Product Structure

IEEE Transactions on Quantum Engineering, 2023
Topological codes, a kind of quantum error correction code, have been used for current quantum computers due to their local qubit layout and high threshold.

Belief Propagation List Decoding of Polar Codes [PDF]

IEEE Communications Letters, 2018
We propose a belief propagation list (BPL) decoder with comparable performance to the successive cancellation list (SCL) decoder of polar codes, which already achieves the maximum likelihood (ML) bound of polar codes for sufficiently large list size $L$.

An Efficient Two-Stage Decoding Scheme for LDPC-CRC Concatenated Codes [PDF]

Entropy
In modern communication systems, the concatenation of a low-density parity-check (LDPC) code with a cyclic redundancy check (CRC) code is commonly used for error correction.

Reduced-Complexity Belief Propagation Decoding for LDPC Codes

IEEE Access
Two methods are proposed to reduce the complexity of the belief propagation (BP) decoding for low-density parity-check (LDPC) codes, with the focus on the layered decoding for quasi-cyclic LDPC (QC-LDPC) codes.
