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.

CONSTRUCTION OF REGULAR LDPC LIKE CODES BASED ON FULL RANK CODES AND THEIR ITERATIVE DECODING USING A PARITY CHECK TREE [PDF]
ICTACT Journal on Communication Technology, 2011 Low density parity check (LDPC) codes are capacity-approaching codes, which means that practical constructions exist that allow the noise threshold to be set very close to the theoretical Shannon limit for a memory less channel.

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

Finite Length Analysis of Low-Density Parity-Check Codes on Impulsive Noise Channels
IEEE Access, 2016 Low-density parity-check (LDPC) codes with very long block lengths are well known for their powerful error correction, but it is not always desirable to employ long codes in communication systems, where latency is a serious issue, such as voice and video

IET Optoelectronics, Volume 19, Issue 1, January/December 2025.We apply a deep learning (DL) technique to binary signalling design for optical wireless communication (OWC) system with a 2D LED transmitter array and an arrayed 2D receiver. It is demonstrated that the DL‐based signalling design algorithm is feasible for OWC system, considering physical channel effect. ABSTRACT Recently, deep learning (DL) techniques

Design of rate-compatible LDPC codes based on uniform shortening distribution
Engineering and Applied Science Research, 2018 Information shortening is a methodology to construct rate-compatible codes. Recently, LDPC codes have been shown that uniform shortening distribution is a criterion to achieve excellent performance.

, 2018 In this paper, we propose a characterization for non-elementary trapping sets (NETSs) of low-density parity-check (LDPC) codes. The characterization is based on viewing a NETS as a hierarchy of embedded graphs starting from an ETS.

IET Quantum Communication, Volume 6, Issue 1, January/December 2025.This paper evaluates Cascade and LDPC codes for information reconciliation in industrial quantum key distribution systems. We highlight efficient methods for minimising key mismatches and optimising performance by analysing often overlooked aspects and proposing new metrics.

Design of LDPC code for uncorrelated Rayleigh fading channel using modified outage probability
ICT ExpressIn this paper, we propose a new design metric called modified outage probability (MOP) for protograph-based low-density parity-check (LDPC) codes over the uncorrelated Rayleigh fading channel.
