Design of Low-Density Parity-Check Code Pair for Joint Source-Channel Coding Systems Based on Graph Theory. [PDF]
Entropy (Basel), 2023 In this article, a graph-theoretic method (taking advantage of constraints among sets associated with the corresponding parity-check matrices) is applied for the construction of a double low-density parity-check (D-LDPC) code (also known as LDPC code ...

EXIT Charts for Low-Density Algebra-Check Codes. [PDF]
Entropy (Basel)This paper focuses on the Low-Density Algebra-Check (LDAC) code, a novel low-rate channel code derived from the Low-Density Parity-Check (LDPC) code with expanded algebra-check constraints.

An Efficient Two-Stage Decoding Scheme for LDPC-CRC Concatenated Codes. [PDF]
Entropy (Basel)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.

An improved method for counting 6-cycles in low-density parity-check codes [PDF]
Serbian Journal of Electrical Engineering, 2023 Since their rediscovery in the early 1990s, low-density parity-check (LDPC) codes have become the most popular error-correcting codes owing to their excellent performance. An LDPC code is a linear block code that has a sparse parity-check matrix.

Decoding across the quantum low-density parity-check code landscape
Physical Review Research, 2020 We show that belief propagation combined with ordered statistics post-processing is a general decoder for quantum low-density parity-check codes constructed from the hypergraph product.

LDPC Code Design for Nonuniform Power-Line Channels
EURASIP Journal on Advances in Signal Processing, 2007 We investigate low-density parity-check code design for discrete multitone channels over power lines. Discrete multitone channels are well modeled as nonuniform channels, that is, different bits experience various channel parameters.

Low density parity check coding [PDF]
IEEE Communications Letters, 2005 This thesis explores the properties of the family of Low Density Parity Check Codes (LDPCC). In addition to Gallager's original binary regular LDPCCs, the class of irregular LDPCCs and non-binary LDPCCs developed from the binary regular LDPCC is also studied.

On the Stopping Distance of SA-LDPC Codes by Transversal Designs
IEEE Access, 2018 In this paper, we analyze the size of the smallest stopping set (called the stopping distance) for the parity-check matrix of a superposed array low-density parity-check (SA-LDPC) code for column weights 3 and 4 by using the transversal design (TD ...
