3D moving target tracking with measurement fusion of TDoA/FDoA/AoA
ICT Express, 2019 In this paper, we investigate the tracking of the 3D moving target when multiple measurements are available. We propose a particle filter-based 3D target tracking algorithm with measurement of time difference of arrival (TDoA), frequency difference of ...

Sensor Placement to Improve the Positioning Performance Based on Angle of Arrival (AOA)
Wireless Engineering and Technology, 2010 In this paper, a method for sensor placement to improve the placement quality based on angle of arrival of signal in a specific area is proposed. The installation place of sensors may be constrained with specified boundaries. In this me-thod, the criterion of maximum quality of placement is the Cramer-Rao bound.

Optimized hybrid localisation with cooperation in wireless sensor networks [PDF]
, 2017 In this study, the authors introduce a novel hybrid cooperative localisation scheme when both distance and angle measurements are available. Two linear least squares (LLS) hybrid cooperative schemes based on angle of arrival–time of arrival (AoA–ToA) and

3D angle-of-arrival positioning using von Mises-Fisher distribution [PDF]
, 2017 We propose modeling an angle-of-arrival (AOA) positioning measurement as a von Mises-Fisher (VMF) distributed unit vector instead of the conventional normally distributed azimuth and elevation measurements.

mmWave V2V Localization in MU-MIMO Hybrid Beamforming
IEEE Open Journal of Vehicular Technology, 2022 Recent trends for vehicular localization in millimetre-wave (mmWave) channels include employing a combination of parameters such as angle of arrival (AOA), angle of departure (AOD), and time of arrival (TOA) of the transmitted/received signals ...

Hybrid TOA/AOA Approximate Maximum Likelihood Mobile Localization
Journal of Electrical and Computer Engineering, 2010 This letter deals with a hybrid time-of-arrival/angle-of-arrival (TOA/AOA) approximate maximum likelihood (AML) wireless location algorithm. Thanks to the use of both TOA/AOA measurements, the proposed technique can rely on two base stations (BS) only ...
