Indoor localisation is a currently a key issue, from robotics to the Internet of Things. With hardware advancements making Ultra-Wideband devices more accurate and low powered (potentially even passive), this unlocks the potential of having such devices in common place around factories and homes, enabling an alternative method of navigation. Therefore, anchor calibration indoors becomes a key problem...
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...
In this paper, we focus on solving the time delay as a separate problem to the reconstruction of the microphone and sound locations. The time delay estimation appears as one of the main steps in sensor calibration problem, once the time delays are known or estimated, we can solve the time-difference-of-arrival problems by converting them to time-of-arrival problems. In this paper we make use of an...
