Implementation and validation of an Angle of Arrival (AOA) determination system

2015 Conference on Design of Circuits and Integrated Systems (DCIS), 2015
This paper presents the implementation and validation of a complete AoA (Angle of Arrival) system. The AoA system is typically used together with smart antenna technology. In this paper the AoA system is part of a mobile wireless communication positioning system. The implementation includes the array antenna, the front ends and the AoA estimation block,

A novel angle of arrival (AOA) positioning algorithm aided by location reliability prior information

2021 IEEE Wireless Communications and Networking Conference (WCNC), 2021
Recently, the indoor positioning system based on the angle of arrival (AOA) has been widely concerned. The positioning system often contains two steps. The first step is the AOA estimation algorithm and the second step is the positioning algorithm using the estimated AOAs.

Angle of arrival (AoA) estimation by using software defined radios

2016 24th Signal Processing and Communication Application Conference (SIU), 2016
Source direction of arrival (DoA) or angle of arrival (AoA) estimation is one of the vital problems in many wireless communication applications such as radar, radio astronomy, sonar and navigation. The resolution of a source direction of arrival estimation can be improved by an uniform linear array (ULA) system with innovative signal processing ...

Multiport Interferometer-Enabled 2-D Angle of Arrival (AOA) Estimation System

IEEE Transactions on Microwave Theory and Techniques, 2017
A systematic scheme for finding the direction of arrival (DOA) or 2-D angle of arrival (AOA) of an electromagnetic beam is proposed and demonstrated in this paper. This system estimates the respective angle of propagation vector of an incoming plane wave in either horizontal or vertical plane.

Verification of a high precision CMOS sensor for angle-of-arrival (AOA) measurement of LED light in ultra-miniaturized applications

The Integration VLSI Journal, 2020
Abstract In this study a specially revised version of the concept for measuring the angle-of-arrival (AOA) of incidence light was used, which is particularly well suited for the construction of trigonometric sensor concepts with external dimensions of only a few millimeters.

Phase based sector resolution in angle of arrival (AoA) computation using a five element circular array

2015 IEEE MTT-S International Microwave and RF Conference (IMaRC), 2015
Many techniques are employed to passively measure Angle of Arrival (AOA) in different EW systems viz. Amplitude Comparison, Phase Comparison, Time Difference of arrival (TDOA) and Rotary Direction Finding (RDF). ‘Base Line Interferometry (BLI)’ is a phase comparison technique.

Review of angle of arrival (AOA) estimations through received signal strength indication (RSSI) for wireless sensors network (WSN)

2015 International Conference on Computer, Communications, and Control Technology (I4CT), 2015
Awareness of the physical location of each node is required by the many wireless sensor network (WSN) applications. There are various tracking schemes available such as time-of-flight, time difference of arrival and angle of arrival. This review paper focuses and describes previous related work regarding of the angle of arrival (AOA) estimations in ...
