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 ...

On the Design and Implementation and Evaluation of Euclidean Geometry Quasi-Cyclic LDPC Codes for NAND Flash Memories

IEEE Open Journal of the Communications Society
As data storage demands continue to grow, ensuring the reliability of NAND flash devices after a large number of Program/Erase (P/E) cycles have elapsed has become a critical requirement.

Secret Key Extraction Using Stable Channel Impulse Response in OFDM Wireless Networks

IET Communications, Volume 20, Issue 1, January/December 2026.
The process of converting a complex impulse response (CIR) highest peak into a binary sequence is called ‘quantisation’. By quantising the CIR highest peaks, Alice and Bob will generate the secret key bit sequences KA and KB, respectively. The number of CIR highest peaks is infinite, and these highest peaks can be easily selected from the set of CIRs ...

Design of low-density parity-check codes: An overview

, 2011
This article provides an overview of the conflicting design tradeoffs of low-density parity-check (LDPC) codes and thus advocates a more holistic approach to their design for wireless channels.

Joint Blind Identification of Cyclic Codes and Synchronization Scramblers From Synchronous Scrambling Sequences of Cyclic Codes Based on Soft Decision Information

IET Communications, Volume 20, Issue 1, January/December 2026.
A communication model for collaborative and non‐collaborative scenarios is proposed, where the error correction code used by the transmitter is a cyclic code and the scrambler used is a synchronous scrambler. The contents of the dashed boxes are the tasks of the non‐collaborative receiver and our research targets the contents of the red boxes, that is,

Generalized Low-Density Parity-Check Coding Aided Multilevel Codes

, 2006
Classic Low-Density Parity-Check (LDPC) codes have recently been used as component codes in Multilevel Coding (MLC) due to their impressive BER performance as well as owing to their flexible coding rates.

Quantum Low-Density Parity-Check Codes

PRX Quantum, 2021
Quantum error correction is an indispensable ingredient for scalable quantum computing. In this Perspective we discuss a particular class of quantum codes called “quantum low-density parity-check (LDPC) codes.” The codes we discuss are alternatives to ...

A Two‐Stage Genetic Algorithm for Joint Optimization of PAPR and PSLR for Precise Signal Reconstruction in OFDM‐ISAC Systems

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper presents a two‐stage genetic algorithm based waveform design framework for OFDM integrated sensing and communication (ISAC) systems. In Stage‐1, a multi‐objective genetic algorithm jointly optimizes the peak‐to‐average power ratio (PAPR) and peak sidelobe level ratio (PSLR) under forward error correction and reserved subcarrier constraints ...

Construction of regular quasi-cyclic protograph LDPC codes based on Vandermonde matrices

, 2008
In this contribution, we investigate the attainable performance of quasi-cyclic (QC) protograph Low-Density Parity-Check (LDPC) codes for transmission over both Additive White Gaussian Noise (AWGN) and uncorrelated Rayleigh channels.

Age‐of‐Information‐Aware Bandwidth Resource Allocation Strategy for NR‐V2X

IET Communications, Volume 20, Issue 1, January/December 2026.
3rd Generation Partnership Project (3GPP) introduces new medium access control features in New Radio Vehicle‐to‐Everything (NR‐V2X) Mode 2, such as the semi‐persistent scheduling re‐evaluation mechanism, and specifies decentralised congestion control based on system‐level metrics including channel busy ratio and channel occupancy ratio, these ...
