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,

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 ...

Efficient LDPC Code Design based on Genetic Algorithm for IoT Applications

EAI Endorsed Transactions on Industrial Networks and Intelligent Systems
In this paper, we propose a low-density parity check (LDPC) code design scheme that improves the performance of the existing genetic algorithm-based LDPC scheme. In particular, we enhance the performance of the LDPC code by removing the girth-4 property

An Efficient Method to Construct Parity-Check Matrices for Recursively Encoding Spatially Coupled LDPC Codes †

Entropy, 2016
Spatially coupled low-density parity-check (LDPC) codes have attracted considerable attention due to their promising performance. Recursive encoding of the codes with low delay and low complexity has been proposed in the literature but with constraints ...

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 ...

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.

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,

Performance of Data‐Driven 5G OFDM‐Based Passive Radar Under Dynamic Modulation Order and LDPC Coding

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This article evaluates the performance of a data‐driven 5G OFDM‐based passive radar under dynamic modulation orders and low‐density parity‐check (LDPC) coding for integrated sensing and communication (ISAC) applications. Simulations demonstrate that maintaining standard communication reliability via LDPC coding minimises signal reconstruction errors ...
