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 ...

Angle-of-Arrival (AOA) Visible Light Positioning (VLP) System Using Solar Cells With Third-Order Regression and Ridge Regression Algorithms [PDF]
IEEE Photonics Journal, 2020 We put forward and demonstrate a angle-of-arrival (AOA) based visible-light-positioning (VLP) system using quadrant-solar-cell (QSC) and third-order ridge regression machine learning (RRML) to improve the positioning accuracy.

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

Estimating Angle of Arrival (AoA) of multiple Echoes in a Steering Vector Space [PDF]
CoRR, 2021 Consider a microphone array, such as those present in Amazon Echos, conference phones, or self-driving cars. One of the goals of these arrays is to decode the angles in which acoustic signals arrive at them. This paper considers the problem of estimating K angle of arrivals (AoA), i.e., the direct path's AoA and the AoA of subsequent echoes ...

Drone’s Angle-of-Arrival Estimation Using a Switched-Beam Antenna and Single-Channel Receiver [PDF]
SensorsIn this study, we propose a method to estimate the Angle-of-Arrival (AoA) of OFDM-based drone signals with wideband and burst characteristics using only a single-channel receiver and a switched-beam antenna.
