Random Sign Repetition Time-Hopping UWB with Multiuser Detection
EURASIP Journal on Wireless Communications and Networking, 2005 A modified time-hopping (TH) ultra-wideband (UWB), called the random sign repetition TH-UWB, is considered to improve the performance of the minimum mean square error (MMSE) multiuser detector.

Design of compact balanced ultra‐wideband bandpass filter with half mode dumbbell DGS
Electronics Letters, 2016 A new compact balanced ultra‐wideband (UWB) bandpass filter using half mode dumbbell defected ground structure (DGS) is presented. To realise the UWB response, the ‘T’ shape multiple‐mode resonator with short‐ended stub is employed.

Electronics Letters, Volume 62, Issue 1, January/December 2026.Child‐presence detection systems based on ultra‐wideband radar can suffer false alarms when trunk‐lid motion resembles in‐cabin human activity. We propose a lightweight streaming time‐domain detector that uses sliding‐window skewness and kurtosis of the radar amplitude to distinguish stationary trunk plateaus from irregular human motion without ...

Characterization of an aperture-stacked patch antenna for ultra-wideband wearable radio systems
Journal of Telecommunications and Information Technology, 2005 This paper presents, for the first time, the time-domain characteristics of an aperture-stacked patch antenna (ASPA) for ultra-wideband (UWB) wearable devices. The methodology of antennas characterization for UWB radio systems is also outlined.

IET Networks, Volume 15, Issue 1, January/December 2026.This work investigates suitable MAC protocols for medical optical wireless body‐area networks (WBANs), focussing on multiple access management. Using realistic channel models, we evaluate the network performance in terms of energy efficiency, quality‐of‐service and scalability for different IEEE protocols, for both intra‐ and extra‐WBAN connectivity in
