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.

Analysis of Feature Visibility in Non-Line-Of-Sight Measurements
2019 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2019We formulate an equation describing a general Non-line-of-sight (NLOS) imaging measurement and analyze the properties of the measurement in the Fourier domain regarding the spatial frequencies of the scene it encodes. We conclude that for a relay wall with finite size, certain scene configurations and features are not detectable in an NLOS measurement.

GNSS positioning in non-line-of-sight context—A survey
2016 IEEE 19th International Conference on Intelligent Transportation Systems (ITSC), 2016The reliable and accurate localization of people and vehicles is one of the challenges of intelligent transportation systems (ITS)s. This has led to a variety of technical approaches in recent years. Towards an exact positioning via Global Navigation Satellite Systems (GNSS)s the visibility of satellites is an important factor. In this paper, we review
