On fuzzy syndrome hashing with LDPC coding [PDF]
Proceedings of the 4th International Symposium on Applied Sciences in Biomedical and Communication Technologies, 2011 The last decades have seen a growing interest in hash functions that allow some sort of tolerance, e.g. for the purpose of biometric authentication. Among these, the syndrome fuzzy hashing construction allows to securely store biometric data and to perform user authentication without the need of sharing any secret key.

A path splitting and pruning strategy on list decoder for PAC codes
IET Communications, Volume 18, Issue 18, Page 1292-1299, November 2024.The paper introduces a novel low‐complexity list decoding algorithm for polarization‐adjusted convolutional codes. By incorporating path splitting and pruning strategies based on highly reliable information bits, our algorithm significantly reduces decoding complexity while maintaining optimal performance.

Research on unequal error protection of irregular LDPC codes
Tongxin xuebao, 2005 An irregular low-density parity-check （LDPC） code with unequal error protection （UEP） property was proposed. A weight-increasing parity-check （WIPC） matrix was constructed.

Binary Representaion for Non-binary LDPC Code with Decoder Design [PDF]
arXiv, 2020 The equivalent binary parity check matrices for the binary images of the cycle-free non-binary LDPC codes have numerous bit-level cycles. In this paper, we show how to transform these binary parity check matrices into their cycle-free forms. It is shown that the proposed methodology can be adopted not only for the binary images of non-binary LDPC codes

Decoding Optimization for 5G LDPC Codes by Machine Learning
IEEE Access, 2018 In this paper, we propose a generalized minimum-sum decoding algorithm using a linear approximation (LAMS) for protograph-based low-density parity-check (PB-LDPC) codes with quasi-cyclic (QC) structures.

IET Communications, Volume 18, Issue 17, Page 1071-1078, October 2024.The study integrates dimmable constant weight polar‐coded non‐orthogonal multiple access (CWPC‐NOMA) with orthogonal space‐time block coding (OSTBC) for visible light communication (VLC). The proposed scheme enhances spectral efficiency and reliability while optimizing resource utilization and leveraging transmit diversity.

Differentially Encoded LDPC Codes—Part II: General Case and Code Optimization
EURASIP Journal on Wireless Communications and Networking, 2008 This two-part series of papers studies the theory and practice of differentially encoded low-density parity-check (DE-LDPC) codes, especially in the context of noncoherent detection. Part I showed that a special class of DE-LDPC codes, product accumulate

CeSR + Assisted LDPC: A Holistic Strategy to Improve MLC NAND Flash Reliability
IEEE Access, 2020 NAND flash suffers from program interference and retention errors, which negatively affect its reliability. Existing schemes preprocess raw data before writing them to reduce Raw Bit Error Rate (RBER) and leverage ECCs (such as LDPC codes) to reduce ...

Deriving Good LDPC Convolutional Codes from LDPC Block Codes [PDF]
arXiv, 2010 Low-density parity-check (LDPC) convolutional codes are capable of achieving excellent performance with low encoding and decoding complexity. In this paper we discuss several graph-cover-based methods for deriving families of time-invariant and time-varying LDPC convolutional codes from LDPC block codes and show how earlier proposed LDPC convolutional ...
