Non-Line-of-Sight Localization in Multipath Environments
IEEE Transactions on Mobile Computing, 2008This paper presents a comprehensive Non Line of Sight (NLOS) localization scheme and a least square estimator that leverages on the bi-directional estimation of the Angle of Arrival (AOA) and Time of Arrival (TOA) of signals exchanged between mobile and reference devices.

Non-Line-of-Sight Positioning for Mmwave Communications
2018 IEEE 19th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2018Using information about the wireless communication channel is a well known approach to estimate a users position. So far it has been shown that such methods can provide positioning information in line-of-sight (LOS) situations by estimating channel properties like time of flight, direction of arrival, and direction of departure of a link between a ...

Foveated Non-line-of-sight Imaging
Imaging and Applied Optics Congress, 2020Existing non-line-of-sight imaging techniques suffer from a tradeoff between field of view and spatial resolution. We propose an imaging system that tackles this tradeoff by efficiently combining information from transient imaging and correlography subsystems.

Non-Line-of-Sight Identification Without Channel Statistics
IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020Identifying non-line-of-sight (NLOS) conditions is important to discard, or improve, any location estimates that have been estimated with NLOS ranges. Typically, NLOS identification relies on channel statistics that have been collected for both LOS and NLOS channels. We investigate NLOS identification using distance residuals instead.

On the Value of Collaboration in Non-Line-of-Sight Location Estimation
2014 IEEE Military Communications Conference, 2014In this paper, we investigate the benefit of inter-node collaboration in multidimensional location estimation under nonline-of-sight signal propagation conditions using time-of-arrival range observations. Specifically, for a network of arbitrary size, we establish the value of collaboration for node positioning by proving that the inclusion of an ...

Non-Line-of-Sight Microwave Backhaul in Heterogeneous Networks
2013 IEEE 78th Vehicular Technology Conference (VTC Fall), 2013In this paper we present a study on the applicability and performance of microwave backhauling of small-cells in a heterogeneous network. Microwave backhaul in non-line-of-sight (NLOS) between a hub and a client provides a cost efficient and flexible small-cell deployment.

Analysis of wireless geolocation in a non-line-of-sight environment
IEEE Transactions on Wireless Communications, 2006We present an analysis of the time-of-arrival (TOA), time-difference-of-arrival (TDOA), angle-of-arrival (AOA) and signal strength (SS) based positioning methods in a non-line-of-sight (NLOS) environment. Single path (line-of-sight (LOS) or NLOS) propagation is assumed.
