Digital image information hiding algorithm research based on LDPC code
EURASIP Journal on Image and Video Processing, 2018 LDPC (low-density parity-check code) is a parity check code, and its performance is very close to Shannon limit. It is a sort of good channel code which has good ability of error correction. The coding can be introduced to an information-hiding algorithm

Fast bootstrap and reliable readout using hidden references for DNA data storage
iMeta, Volume 5, Issue 1, February 2026.This study provides a bootstrap readout framework for DNA data storage based on multiple‐fold hidden references. We employ a multi‐stage alignment and error correction strategy, transforming the de novo readout into a resequencing‐like workflow. Correlation to the hidden watermark reference identifies low‐error‐rate reads, and bit‐wise consensus ...

Construction of Short-length High-rates Ldpc Codes Using Difference Families [PDF]
, 2007 Low-density parity-check (LDPC) code is linear-block error-correcting code defined by sparse parity-check matrix. It isdecoded using the massage-passing algorithm, and in many cases, capable of outperforming turbo code.

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.The sixth generation (6G) wireless networks are used to provide a large coverage, and also this generation needed to support different emerging applications in harsh areas with higher user equipment mobility. For the above case, a new modulation technique called orthogonal time–frequency space (OTFS) modulation has emerged as a promising technique to ...

Design and Performance of Rate-compatible Non-Binary LDPC Convolutional Codes
, 2011 In this paper, we present a construction method of non-binary low-density parity-check (LDPC) convolutional codes. Our construction method is an extension of Felstroem and Zigangirov construction for non-binary LDPC convolutional codes.

Acceleration of low density parity check code (LDPC) decoding by successive overrelaxations [PDF]
Electronics Letters, 2018 Belief propagation and variants are the usual decoding algorithms for low‐density parity check codes. The successive overrelaxations are applied to increase the convergence speed of the decoding process. Performances are reported and improvements over the reference algorithms are observed.

PERBANDINGAN KINERJA LDPC PADA KANAL AWGN DENGAN MODULASI QPSK DAN BPSK [PDF]
, 2011 Low Density Parity Check (LDPC) codes are one class of linear block coding techniques. The name comes from the characteristics of the LDPC parity check matrix was that only contain a little bit of '1 'if compared with the number of bits of '0'.
