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 ...

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.

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 ...

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 Measurement
The 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

Optical angle‐of‐arrival (AoA) sensor for the motion analysis of knee joints

Electronics Letters, 2017
The most widely used clinical technique for estimating bone movements in knee joints with acceptable accuracy utilises implantation of heavy metallic beads into the bones. These small metallic objects become visible as highly contrasting features in captured radiographs, thus facilitating post kinematic assessment of bones in human joints with pinpoint
