Improved Angle-of-Arrival Estimation of Narrow Gaussian Beams for Mobile FSO Platforms

IEEE Transactions on Aerospace and Electronic Systems
Due to the narrow beamwidths of laser Gaussian beams, accurate tracking of laser beam’s angle-of-arrival is an important problem in mobile free-space optical communications.

On the security of Angle of Arrival estimation

2016 IEEE Conference on Communications and Network Security (CNS), 2016
Angle of Arrival (AoA) estimation has found its way to a wide range of applications. Much attention has been paid to study different techniques for AoA estimation and its applications for jamming suppression, however, security vulnerability issues of AoA estimation itself under hostile activity have not been paid the same attention.

Estimation of angles-of-arrival for wideband sources

ICASSP '84. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
High resolution direction of arrival estimation for multiple wideband sources is discussed in this paper. The proposed method involves two steps. Preliminary estimates of the angles are obtained via an eigendecomposition method such as MUSIC for several non-overlapping bands of frequency.

Estimation of angles of arrivals of broadband signals

ICASSP '87. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
A high resolution one-step algorithm for estimating the angles of arrivals of multiple wideband sources is proposed. For a dense and equally spaced array structure, a bilinear transformation is utilized in frequency domain for coherent signal subspace processing.

A simple technique for angle of arrival measurement

2008 IEEE Antennas and Propagation Society International Symposium, 2008
A simple method to calculate the angle of arrival is presented in this paper. The advantages of this method are the unlimited number of the detected angle of arrival in hand and the fact that we donpsilat need to know the nature of the radiating sources in the other hand. However, some disadvantages have been seen.

Network localization using angle of arrival

2008 IEEE International Conference on Electro/Information Technology, 2008
In this paper, we propose two localization methods using angle of arrival (AoA) information. We assume that nodespsila axis orientations are unknown. Therefore, all AoA measurements are employed to calculate the angle differences of two different nodes viewed by the third one.

Angle–of–Arrival (AoA) Factorization in Multipath Channels

ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021
This 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.

Time-of-arrival, angle-of-arrival, and angle-of-departure statistics of a novel simplistic disk channel model

2011 5th International Conference on Signal Processing and Communication Systems (ICSPCS), 2011
This paper introduces a novel simplistic geometrical disk scattering model in which the local scatterers are uniformly distributed in polar coordinates within a disk centered on the mobile station (MS). The proposed joint uniform distribution in polar coordinates results in a higher concentration of scatterers around the disk center and a lower ...

The elevation angle of mobile radio signal arrival

IEEE Transactions on Vehicular Technology, 1973
Field measurements of mobile radio signals have shown that signal arrival is concentrated in elevation angles lower than 16°. This suggests use of an omnidirectional antenna with vertical directivity, instead of the usual whip antenna, to increase average signal strength as a further improvement in the advantages of diversity reception.
