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

Carrying Carbon? Negative and Positive Carbon Leakage With International Transport
Journal of Economics &Management Strategy, Volume 34, Issue 4, Page 971-990, Winter 2025.ABSTRACT This paper studies how carbon pricing affects greenhouse gas (GHG) emissions from international transport, production, and consumption of traded goods by modeling the international transport sector explicitly. Strategic behavior of a transport firm generates a novel mechanism of carbon leakage across borders and sectors.

UAVs‐Assisted Low‐Bit Quantized CF‐mMIMO Systems With MmWave Communications Under MRC Detection
IET Communications, Volume 19, Issue 1, January/December 2025.ABSTRACT The cell‐free massive multiple input multiple output (CF‐mMIMO) approach, due to its high coverage and the ability to attenuate the large‐scale fading impacts in wireless communications, has drawn a lot of attention. Additionally, because of their movement ability, low power, and low‐cost employed infrastructures, unmanned aerial vehicles ...
