Optimal Sensor Arrangements in Angle of Arrival (AoA) and Range Based Localization with Linear Sensor Arrays [PDF]

Sensors, 2013
This paper investigates the linear separation requirements for Angle-of-Arrival (AoA) and range sensors, in order to achieve the optimal performance in estimating the position of a target from multiple and typically noisy sensor measurements. We analyse the sensor-target geometry in terms of the Cramer–Rao inequality and the corresponding Fisher ...

Utilizing Lighting Design Software for Simulation and Planning of Machine Learning Based Angle-of-Arrival (AOA) Visible Light Positioning (VLP) Systems [PDF]

IEEE Photonics Journal, 2022
We propose to utilize a commercially available DIALux lighting design software for simulation and planning of machine learning (ML) based angle-of-arrival (AOA) visible light positioning (VLP) systems. Here, different ML models, for example, second order linear regression (LR), artificial neural-network (ANN), and convolutional neural-network (CNN) are

Implementation and Validation of an Angle of Arrival (AoA) Determination System for Real-time on-board Train Positioning

Transportation Research Procedia, 2016
AbstractThis paper presents the implementation of an Angle of Arrival (AoA) estimation algorithm using FPGA technology as a part of a Smart Train Positioning System (STPS). The STPS takes advantage of the combination of different technologies and techniques, such as GNSS and the AoA of the GSM-R signals, to determine the real time train position ...
