The Analytical Description of Regular LDPC Codes Correcting Ability
Transport and Telecommunication, 2014 The analytical description of regular LDPC (Low-Density Parity Check) codes correcting ability has been investigated. The statistical dependencies for the maximum number of corrected bits per the code word as a function of LDPC code word length and code ...

Effective identification of dominant fully absorbing sets for Raptor-like LDPC codes
ETRI Journal, 2023 The error-rate floor of low-density parity-check (LDPC) codes is attributed to the trapping sets of their Tanner graphs. Among them, fully absorbing sets dominantly affect the error-rate performance, especially for short blocklengths.

Threshold Analysis of Non-Binary Spatially-Coupled LDPC Codes with Windowed Decoding
, 2014 In this paper we study the iterative decoding threshold performance of non-binary spatially-coupled low-density parity-check (NB-SC-LDPC) code ensembles for both the binary erasure channel (BEC) and the binary-input additive white Gaussian noise channel (

LDPC convolutional codes based on braided convolutional codes [PDF]
2008 IEEE International Symposium on Information Theory, 2008 We introduce and analyze new constructions of LDPC convolutional codes and their tail-biting versions which are obtained from braided convolutional codes. The basic ideas behind the encoding and decoding architectures for these codes are presented. Additionally, asymptotic results concerning the iterative thresholds are shown for different ensembles ...

A Non‐Binary Dual Cascade Polar Codes Construction and Low‐Complexity SCL Decoding
Electronics Letters, Volume 61, Issue 1, January/December 2025.First, we design an error‐correction approach including two cascade non‐binary polar coding (NB‐CPolar) structures and a cyclic redundancy check (CRC) code. Second, we propose a low‐complexity decoding algorithm based on non‐binary successive cancellation list (NB‐LSCL) decoding.

Novel construction of QC-LDPC codes with modified 2-D GRS codes
Tongxin xuebao, 2015 The construction method for QC-LDPC (quasi-cyclic low density parity-check) code with modified two-dimensional generalized reed-solomon (2-D GRS) code is proposed using the generator polynomial of GRS code,so thus the constructed code can have better ...

Iterative decoding of SOVA and LDPC product code for bit-patterned media recoding
AIP Advances, 2018 The demand for high-density storage systems has increased due to the exponential growth of data. Bit-patterned media recording (BPMR) is one of the promising technologies to achieve the density of 1Tbit/in2 and higher.

Minimum Distance Distribution of Irregular Generalized LDPC Code Ensembles
, 2013 In this paper, the minimum distance distribution of irregular generalized LDPC (GLDPC) code ensembles is investigated. Two classes of GLDPC code ensembles are analyzed; in one case, the Tanner graph is regular from the variable node perspective, and in ...

On the Invisible Backdoor Attacks on Peer‐to‐Peer Semantic Vehicular Networks
Electronics Letters, Volume 61, Issue 1, January/December 2025.ABSTRACT Peer‐to‐peer semantic vehicular networks (P2P‐SVNs) use semantic communication to enable efficient vehicle‐to‐vehicle interaction by exchanging meaning instead of raw data. However, P2P‐SVNs face unique backdoor threats where attackers embed triggers in semantic features. Current research predominantly focuses on explicit trigger patterns that
