Spatially Coupled Generalized Low-Density Parity-Check Codes Over Class-A Impulsive Noise Channels
IEEE Access, 2019 In this paper, a class of spatially coupled generalized low-density parity-check (SC-GLDPC) codes with minimum coupling width is introduced to mitigate the Class-A impulsive noise. Codes with minimum coupling width are beneficial to simple code structure,

Hybrid neural coded modulation: Design and training methods
ICT Express, 2022 We propose a hybrid coded modulation scheme which composes of inner and outer codes. The outer-code can be any standard binary linear code with efficient soft decoding capability (e.g. low-density parity-check (LDPC) codes).

New Codes on Graphs Constructed by Connecting Spatially Coupled Chains
, 2012 A novel code construction based on spatially coupled low-density parity-check (SC-LDPC) codes is presented. The proposed code ensembles are described by protographs, comprised of several protograph-based chains characterizing individual SC-LDPC codes. We

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 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.

Performance Evaluation of Low Density Parity Check (LDPC) Codes Over Gigabit Ethernet Protocol
Transactions on Networks and Communications, 2016 Error Correcting Low density Parity Check codes enable the communication systems to have a low-power, reliable transmission over noisy channels and can achieve data rates very close to Shannon limit when iteratively decoded. They are used in many digital communication systems such as digital video broadcasting (DVB-S2), MIMO-WLAN (802.11n), WMAN ...

IET Quantum Communication, Volume 6, Issue 1, January/December 2025.A novel secure image transmission scheme has been proposed using the logistic chaos map and the Ekert protocol. The quantum key distribution can be used to generate seed parameters for classical chaos, thus ensuring a strong encryption method. ABSTRACT The emergence of quantum computing has introduced unprecedented security challenges to conventional ...
