Sensor Placement to Improve the Positioning Performance Based on Angle of Arrival (AOA) [PDF]
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.

Low complexity and high accuracy angle of arrival estimation using eigenvalue decomposition with extension to 2D AOA and power estimation [PDF]
EURASIP Journal on Wireless Communications and Networking, 2011 In this paper, an angle of arrival (AOA) estimator is presented. Accurate AOA estimation is very crucial for many applications such as wireless positioning and signal enhancement using space processing techniques. The proposed estimator is based upon applying the eigenvalue decomposition (EVD) method on the crosscorrelation matrix of the received ...

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

High Resolution Methods for Angle of Departure (AOD) and Angle of Arrival (AOA) Estimation in Bistatic Multiple-Input-Multiple-Output (MIMO) Radar Systems [PDF]
Indian Journal of Science and Technology, 2018 Objectives: In this paper we make a comparative study between two adapted methods for the estimation of the angle of departure and the angle of arrival in a Bistatic multiple input multiple output radar system. Methods: We have adapted the high resolution methods known in the literature to the estimation of the parameters of the sources with a Bistatic

Channel Estimation For Mimo-Ofdm Systems of Joint Angle-of-Departure (AOD) or Angle-of-Arrival (AOA)
International Journal of Innovative Technology and Exploring Engineering, 2019 Beamforming with gathering mechanical assembly displays has been considered as an engaging advancement in future remote correspondence structures. To coordinate beamforming, one has to know the angle-of-departure (AoD) or angle-of-arrival (AoA). For data disclosure, the beneficiary in like manner has to know station response.

Inferring Helmet Compliance on E-Scooters Using Bluetooth and Angle-of-Arrival (AoA) Technology
IEEE Transactions on Instrumentation and MeasurementThe use of e-scooters and the associated head injuries have increased significantly in recent years. To protect the head and face of the riders, helmets are essential equipment, sometimes mandatory according to the regulations, which makes them an important research target. In this article, we propose a practical helmet monitoring system for e-scooters
