Regularised Hyper Parameter Bi Level Optimisation With Continual Learning Based Deep Neural Network for Beamforming in Ultra‐Wide Band System

IET Communications, Volume 20, Issue 1, January/December 2026.
This research proposes a Regularised Hyperparameter Bilevel Optimisation with Continual Learning‐based Deep Neural Network (RHBO‐CLDNN) for beamforming in an Ultra‐Wide Band (UWB) system. The RHBO ensures the hyperparameter efficiency at both upper and lower levels, which allows DNN to fine‐tune the unique characteristics of the UWB system, which leads

An Indoor Robust Localization Algorithm Based on Data Association Technique

Sensors, 2020
As a key technology of the Internet of Things, wireless sensor network (WSN) has been used widely in indoor localization systems. However, when the sensor is transmitting signals, it is affected by the non-line-of-sight (NLOS) transmission, and the ...

Secure Transmission in ISAC Systems Aided by Active STAR‐RIS

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper investigates the secure transmission problem in an active simultaneous transmitting and reflecting intelligent reflecting surfaces (STAR‐RIS)‐aided integrated sensing and communication downlink system. Our objective is to maximize the sum secrecy rate by jointly optimizing the base station beamforming vectors, the sensing signal covariance ...

Trade‐off‐aware Optimisation of UAV Base Station Deployment in Smart IoT Environments Using Strength Pareto Evolutionary Algorithm

IET Communications, Volume 20, Issue 1, January/December 2026.
This study presents a Strength Pareto Evolutionary Algorithm 2 (SPEA2)‐based multi‐objective framework for optimised deployment of drone base stations (DBSs) in Internet of Things (IoT) networks. The model simultaneously enhances user coverage and reduces path loss under realistic urban propagation conditions. Results confirm the framework's ability to

Near‐Field 3D Stochastic Channel Modelling and Performance Analysis for Cooperative STAR‐RIS Systems With Cylindrical Transmit Arrays

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper develops a near‐field three‐dimensional geometry‐based stochastic channel model for cooperative STAR‐RIS systems equipped with cylindrical transmit arrays at the base station. The proposed model captures spherical wavefront propagation effects and coupled azimuth‐elevation characteristics under realistic near‐field conditions.

Neurodynamic robust adaptive UWB localization algorithm with NLOS mitigation

Scientific Reports
For the robust localization in mixed line-of-sight (LOS) and non-line-of-sight (NLOS) indoor environments, we proposed a max-min optimization estimator from a measurement model and introduced an adaptive loss function to optimize the estimation. However,
