Double Reply ToA Algorithm Robust to a Timer Offset for a UWB System

This paper deals with a new ranging algorithm in an ultra-wideband system. The conventional ToA algorithm determines the distance between devices by estimating the propagation time. However, due to different timer offsets in each device, the accuracy of this estimation can be compromised. In this pa...

Beschreibung
Zusammenfassung:	This paper deals with a new ranging algorithm in an ultra-wideband system. The conventional ToA algorithm determines the distance between devices by estimating the propagation time. However, due to different timer offsets in each device, the accuracy of this estimation can be compromised. In this paper, a double reply ToA algorithm is proposed to increase the ranging accuracy without increasing hardware complexity.
