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...
This paper presents an algorithm that enables anchor-less localization for pairs of static Impulse Radio - Ultra Wide Band (IR-UWB) devices in a room. The estimation progresses through a tree, as the most significant received paths are successively considered. Unlikely path parameters estimates are progressively rejected, relying on cross-correlation (i.e. with respect to predicted waveforms), as...
This paper presents an algorithm that interprets the waveforms associated with received mutipath components in order to estimate their Direction of Arrival (DoA), Direction of Departure (DoD) and Incident Angle to the Indoor Surface (IAIS) in the context of Impulse Radio - Ultra Wide Band (IR-UWB) communications. The proposed solution combines a deterministic description of the filtering effects of...
This paper presents an algorithm that interprets the specificities of the received waveforms associated with well-isolated multipath echoes, depending on the type of interaction and on the direction-dependent signal deformations due to antennas. The goal is to jointly estimate Direction of Arrival (DoA), Direction of Departure (DoD) and reflecting material for simple-bounce interaction in a peer-to-peer...
In this paper, we present an algorithm that interprets the specificities of the received direct path, depending on the particular deformations due to antennas, in the context of Impulse Radio - Ultra Wide Band (IR-UWB) peer-to-peer communications. The goal is to jointly estimate direct path Direction of Arrival (DoA) and Direction of Departure (DoD). The proposed technique is mainly based on prior...
