Two-Step Time of Arrival Estimation for Pulse-Based Ultra-Wideband Systems

open access: yesEURASIP Journal on Advances in Signal Processing, 2008
In cooperative localization systems, wireless nodes need to exchange accurate position-related information such as time-of-arrival (TOA) and angle-of-arrival (AOA), in order to obtain accurate location information.

Decawave UWB Clock Drift Correction and Power Self-Calibration

open access: yesSensors, 2019
The position accuracy based on Decawave Ultra-Wideband (UWB) is affected mainly by three factors: hardware delays, clock drift, and signal power. This article discusses the last two factors.
