Title
Robust time-of-arrival self calibration and indoor localization using Wi-Fi round-trip time measurements
Abstract
The problem of estimating receiver-sender node positions from measured receiver-sender distances is a key issue in different applications such as microphone array calibration, radio antenna array calibration, mapping and positioning using UWB and mapping and positioning using round-trip-time measurements between mobile phones and Wi-Fi-units. Thanks to recent research in this area we have an increased understanding of the geometry of this problem. In this paper, we study the problem of missing information and the presence of outliers in the given data. We propose a novel hypothesis and test framework that efficiently finds initial estimates of the unknown parameters and combine such methods with optimization techniques to obtain accurate and robust systems. The proposed systems are evaluated using Wi-Fi round-trip time measurements to give a realistic example of indoor localization. The resulting map of the anchor points is validated against ground truth measurements with promising results.
