An Adaptive UWB Synchronization Algorithm based on The IEEE 802.15.4-2020 Protocol

In recent years, UWB technology has become a promising solution for indoor positioning. UWB has advantages such as wide bandwidth and strong resistance to multipath interference, making it widely used in the field of indoor positioning. The accuracy of indoor positioning critically depends on the ranging precision, which is closely related to the physical layer synchronization. In this study, a comprehensive simulation of the IEEE 802.15.4-2020 protocol’s UWB physical layer was performed. We focused on analyzing a new method to improve synchronization accuracy and capture efficiency under high noise conditions. The simulation results demonstrated the effectiveness of this method in enhancing synchronization accuracy.
