Distributed massive UAV jamming optimization algorithm with artificial bee colony
IET Communications, Volume 17, Issue 2, Page 197-206, January 2023., 2023 Abstract With the massive application of unmanned aerial vehicles (UAVs) in disaster relief, fire protection, security and other fields, jamming countermeasures to UAVs in airports and competition venues have become the core link of security in high‐level matches and important places. The existing jamming sources are mainly single point jamming. Due to

Comparison and Synergy of BPSK and BOC Modulations in GNSS Reflectometry
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 Signals from global navigation satellite systems (GNSSs) have been advocated as opportunities for remote sensing of the Earth. In the multi-GNSS era, signals from different constellation, at different frequency, and under different modulation are ...

Addressing robust travel mode identification with individual trip‐chain trajectory noise reduction
IET Intelligent Transport Systems, Volume 17, Issue 1, Page 129-143, January 2023., 2023 Abstract Identifying travel modes from Global Navigation Satellite System (GNSS) trajectories is helpful for traffic management. In mode identification, the motion features are extracted from trajectories to train the classifiers. However, features would be distorted by the positioning noise when migrating existing frameworks to poor‐quality tracks ...

GNSS Time Synchronization in Vehicular Ad-Hoc Networks: Benefits and Feasibility [PDF]
Hasan, Khondokar Fida, Yanming Feng, and Yu-Chu Tian. "GNSS Time
Synchronization in Vehicular Ad-Hoc Networks: Benefits and Feasibility." IEEE
Transactions on Intelligent Transportation Systems (2018), 2018 Time synchronization is critical for the operation of distributed systems in networked environments. It is also demanded in vehicular ad-hoc networks (VANETs), which, as a special type of wireless networks, are becoming increasingly important for emerging cooperative intelligent transport systems.
