Implementation and validation of an Angle of Arrival (AOA) determination system
2015 Conference on Design of Circuits and Integrated Systems (DCIS), 2015This 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,

Angle of arrival (AoA) estimation by using software defined radios
2016 24th Signal Processing and Communication Application Conference (SIU), 2016Source 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, 2017A 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.

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.

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.

Angle–of–Arrival (AoA) Factorization in Multipath Channels
ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021This paper considers the problem of estimating K angle of arrivals (AoA) using an array of M > K microphones. We assume the source signal is human voice, hence unknown to the receiver. Moreover, the signal components that arrive over K spatial paths are strongly correlated since they are delayed copies of the same source signal.

A novel angle of arrival (AOA) positioning algorithm aided by location reliability prior information
2021 IEEE Wireless Communications and Networking Conference (WCNC), 2021Recently, 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.
