LDPC Codes Achieve List Decoding Capacity [PDF]

open access: yesIEEE Annual Symposium on Foundations of Computer Science, 2019
We show that Gallager's ensemble of Low-Density Parity Check (LDPC) codes achieves list-decoding capacity with high probability. These are the first graph-based codes shown to have this property.

Nonbinary Spatially-Coupled LDPC Codes on the Binary Erasure Channel [PDF]

open access: yes, 2012
We analyze the asymptotic performance of nonbinary spatially-coupled low-density parity-check (SC-LDPC) codes built on the general linear group, when the transmission takes place over the binary erasure channel.

Performance Analysis for Cooperative Communication System with QC-LDPC Codes Constructed with Integer Sequences

open access: yesDiscrete Dynamics in Nature and Society, 2015
This paper presents four different integer sequences to construct quasi-cyclic low-density parity-check (QC-LDPC) codes with mathematical theory. The paper introduces the procedure of the coding principle and coding.

New Construction of Low-Density Parity-Check Codes Based on Vector Space Over Finite Fields

open access: yesIEEE Access, 2020
Low-Density Parity-Check (LDPC) codes have low linear decoding complexity, which is a kind of good codes with excellent performance. Therefore, LDPC codes have great research value.

Tree-Based Construction of LDPC Codes Having Good Pseudocodeword Weights [PDF]

open access: yes, 2005
We present a tree-based construction of LDPC codes that have minimum pseudocodeword weight equal to or almost equal to the minimum distance, and perform well with iterative decoding.

Partitioning qubits in hypergraph product codes to implement logical gates [PDF]

open access: yesQuantum, 2023
The promise of high-rate low-density parity check (LDPC) codes to substantially reduce the overhead of fault-tolerant quantum computation depends on constructing efficient, fault-tolerant implementations of logical gates on such codes.

Augmented decoders for LDPC codes [PDF]

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
Abstract The performance of a belief propagation decoder for low-density parity-check codes is limited by the presence of trapping sets in the code’s graph. This leads to an error floor at higher signal-to-noise ratios. We propose the use of an augmented decoder which operates by iteratively decoding on a set of graphs which have a subset of repeated ...

On fuzzy syndrome hashing with LDPC coding [PDF]

open access: yesProceedings 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.

Block Markov superposition transmission of LDPC codes

open access: yesJournal of Information and Intelligence, 2023
In this paper, based on the block Markov superposition transmission (BMST) technique, we present a new class of coupled low-density parity-check (LDPC) codes for the transport block (TB)-based transmission to improve the error-correcting performance. For

On the Minimum Distance of Generalized Spatially Coupled LDPC Codes [PDF]

open access: yes, 2013
Families of generalized spatially-coupled low-density parity-check (GSC-LDPC) code ensembles can be formed by terminating protograph-based generalized LDPC convolutional (GLDPCC) codes.
