A simple technique for angle of arrival measurement
2008 IEEE Antennas and Propagation Society International Symposium, 2008A 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, 2008In 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), 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.

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, 1973Field 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.

The angle of arrival (AOA) is the most valuable piece of information that can be obtained from an enemy radar because the radar cannot change its position drastically in a very short time frame (i.e., a few milliseconds). Unfortunately AOA information is also the most difficult information to obtain. It requires several antennas with receivers. The two

Angle-of-Arrival Estimation for UWB Signals Clustered in Angle
2006 1st International Symposium on Wireless Pervasive Computing, 2006In this study, the new signal model suitable for ultrawide band (UWB) environments with random angle spread is proposed to estimate the angle-of-arrivals (AOAs) of clusters in a UWB indoor or indoor-to-outdoor wireless communication. The estimation technique based MUSIC algorithm is investigated and the estimates of the AOA and distribution parameter ...

Angle-of-arrival fluctuations in a turbulent atmosphere
The Journal of the Acoustical Society of AmericaAtmospheric turbulence causes fluctuations in the angle-of-arrival (AOA) of sound waves. These fluctuations adversely affect the performance of sensor arrays used for source detection, ranging, and recognition. This article examines, from a theoretical perspective, the variance of the AOA fluctuations measured with two microphones.

Arrival angle estimation in non-Gaussian noise
Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002This paper considers the problem of estimating the direction of arrival of plane waves from sensor array data. It is shown through a multivariate generalization of Whittle's inequality that the least squares estimator and its subspace-based approximations are inefficient when the noise distribution is non-Gaussian.

On Angle-of-Arrival and Time-of-Arrival Statistics of Geometric Scattering Channels
IEEE Transactions on Vehicular Technology, 2009This paper proposes a hyperbolic distribution to model the distribution of random scatterers between a base station (BS) and the user equipment (UE) in multipath mobile environments. New hyperbolic angle-of-arrival (AoA) probability density function (pdf), power azimuth spectrum (PAS), time-of-arrival (ToA) pdf, and power delay spectrum (PDS) are ...
