In this paper, we propose a solution adapted to Impulse Radio — Ultra Wideband (IR-UWB) integrated receivers devoted to indoor localization, making usage of multipath information under imposed time resolution and low complexity constraints. The Multipath Components (MPCs) can ideally be tracked by capturing their space-time correlation under mobility. The proposed architecture is composed of Multiple...
In this paper we jointly address the problems of node location tracking and indoor mapping in the absence of infrastructure, relying on peer-to-peer IEEE 802.15.4a Impulse Radio - Ultra Wideband (IR-UWB) links. Coarse Time of Arrival (ToA) measurements, which are obtained within a low complexity Energy Detection (ED) receiver, are mapped into the direct path and single-bounce reflected multipath components...
This paper investigates the impact of realistic antennas on joint anchor-less localization and indoor characterization based on Impulse Radio (IR) Ultra Wideband (UWB) communications. In this frame, the Maximum Averaged Likelihood (MAL) algorithm and its extended version are considered, both relying on a tree approach consisting in two stages. The first part of the process, which is common to both...
