Joint Time Synchronisation and Localisation Method by TDOA Observation in 5G Networks

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This work proposes a method for joint time synchronisation and localisation problems and proposes to obtain the initial values of the alternating iteration algorithm through solving the MVIE problem. The simulations showcase the satisfying positioning accuracy and clock synchronisation accuracy of the proposed method.

Machine Learning Approach for Predicting Electromagnetic Shielding Effectiveness of Metallic Grids in the Time and Frequency Domains

open access: yesIET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.
Accurate evaluation of electromagnetic shielding effectiveness (SE) is essential for protecting electronic systems against electromagnetic interference (EMI) and electromagnetic pulses (EMP). This study investigates both time‐domain (TDSE) and frequency‐domain (FDSE) shielding effectiveness of metallic grid structures using full‐wave simulations and ...

Obstacle‐Aware Navigation for MAVs Using Constant Flow Divergence Control and Texton‐Based Visual Cues

open access: yesJournal of Robotics, Volume 2026, Issue 1, 2026.
Tiny flying insects rely heavily on optical flow for landings and navigation. By maintaining a constant optical flow divergence, they can approach targets or obstacles with an exponential decay of both relative distance and velocity. Previous studies have shown that Micro Air Vehicles (MAVs) leverage this control strategy for efficient landings and ...
