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...
In this paper, we propose an estimation scheme to overcome singularities which may deteriorate time difference of arrival (TDoA) based localization accuracy when using least square (LS) estimator. The solution is based on total least square (TLS) estimator. We provide an algorithm of localization which exploits the rank and the condition number of matrices in order to enhance accuracy. The Monte Carlo...
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...
In this paper, localization based on Received Signal Strength (RSS) is investigated assuming a path loss log normal shadowing model. On the one hand, indirect RSS-based estimation schemes are investigated; these schemes are based on two steps of estimation: estimation of ranges from RSS and then estimation of position using weighted least square approximation. We show that the performances of this...
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...
