Design of Low-Density Parity-Check Code Pair for Joint Source-Channel Coding Systems Based on Graph Theory [PDF]

open access: yesEntropy, 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 ...

Array Convolutional Low-Density Parity-Check Codes [PDF]

open access: yesIEEE Communications Letters, 2013
This paper presents a design technique for obtaining regular time-invariant low-density parity-check convolutional (RTI-LDPCC) codes with low complexity and good performance. We start from previous approaches which unwrap a low-density parity-check (LDPC)

Statistical mechanics of low-density parity-check codes [PDF]

open access: greenJournal of Physics A: Mathematical and General, 2004
We review recent theoretical progress on the statistical mechanics of error correcting codes, focusing on low-density parity-check (LDPC) codes in general, and on Gallager and MacKay-Neal codes in particular. By exploiting the relation between LDPC codes and Ising spin systems with multispin interactions, one can carry out a statistical mechanics based

Thresholds of Absorbing Sets in Low-Density Parity-Check Codes [PDF]

open access: greenIEEE Transactions on Communications, 2017
In this paper, we investigate absorbing sets, responsible of error floors in Low Density Parity Check codes. We look for a concise, quantitative way to rate the absorbing sets' dangerousness. Based on a simplified model for iterative decoding evolution, we show that absorbing sets exhibit a threshold behavior. An absorbing set with at least one channel

An improved method for counting 6-cycles in low-density parity-check codes [PDF]

open access: yesSerbian 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.

On Girth Conditioning for Low-Density Parity-Check Codes [PDF]

open access: yesIEEE Transactions on Communications, 2011
Low-density parity-check (LDPC) codes are gaining interest for high data rate applications in both terrestrial and spatial communications. They can be designed and studied through a bipartite graph whose characteristics affect the performance. This paper proposes a low-complexity method to improve the performance of LDPC codes by selectively removing ...
