Optimal Precoders for Tracking the AoD and AoA of a mm-Wave Path [PDF]
, 2018 In millimeter-wave channels, most of the received energy is carried by a few paths. Traditional precoders sweep the angle-of-departure (AoD) and angle-of-arrival (AoA) space with directional precoders to identify directions with largest power.

2D localization with WiFi passive radar and device-based techniques: an analysis of target measurements accuracy [PDF]
, 2018 The aim of the work is to investigate the performance of two localization techniques based on WiFi signals: the WiFi-based passive radar and a device-based technique that exploits the measurement of angle of arrival (AoA) and time difference of arrival ...

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 ...

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

Iterative Regression Based Hybrid Localization for Wireless Sensor Networks
Sensors, 2021 Among various localization methods, a localization method that uses a radio frequency signal-based wireless sensor network has been widely applied due to its robustness against noise factors and few limits on installation location.

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 ...
