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.

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 ...

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,

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.

Performance of ESPRIT and Root-MUSIC for Angle-of-Arrival(AOA) Estimation
2018 IEEE World Symposium on Communication Engineering (WSCE), 2018AOA estimation is used for localization of incident signals such as automotive radar system. [1] There are various methods for estimating the AOA of the signal source. The angle-of-arrival(AOA) estimation algorithms such as MUSIC(MUltiple SIgnal Classification) [2], CBF(conventional beamforming) [3], and capon beamforming [4] require large amounts of ...

On Angle of Arrival (AoA) K̈hler Manifolds Feedback Method for FDD mmWave V2X Systems
2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019The work of cooperative perception realized by mmWave Vehicle to everything (V2X) [3] has pointed out that vehicles require much network bandwidth to exchange sensor information for safe automated driving; e.g., they require higher than 1Gbps V2V bandwidth to ensure safe velocity of 70 km/h.

2019 12th International Conference on Developments in eSystems Engineering (DeSE), 2019
In order to define the location of any electromagnetic transmitting source, two or three directions of arrival (ƒAE, .) estimators are needed to provide two or three different directions for coordination. In the last two decades most of research works are focused on Multiple Signal Classification (MUSIC), and Estimation of Signal Parameters using ...

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.
