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

Blocking Interference Mechanism in Networked Radios Under UWB HPM
This paper conducts a systematic cross‐level analysis of the damage mechanism encompassing ‘electromagnetic interference–hardware impairment–communication performance’ for QPSK‐based networked radios. Using ultra‐wide spectrum pulse signals as the interference source, the study considers the scenario where electromagnetic interference causes damage to ...

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 ...
