A unitary transformation method for angle-of-arrival estimation
IEEE Transactions on Signal Processing, 1991Eigenstructure methods for estimating angles of arrival of radiation sources generally require complex computations in computing eigencomponents of the covariance matrix and calculating the search function. A unitary transformation method that transforms the complex covariance matrix of an equally spaced linear array, which is Hermitian persymmetric ...

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 estimation in atmospheric turbulence
The Journal of the Acoustical Society of America, 2005An angle-of-arrival estimator is derived for acoustic waves that propagate in atmospheric turbulence. The estimator directly accounts for the effects of random fluctuations in the propagation environment. The first and second moments of the sound field, as derived from the theory of wave propagation in a random medium, and realistic atmospheric ...

An experimental angle of arrival estimation system
[1991] Conference Record of the Twenty-Fifth Asilomar Conference on Signals, Systems & Computers, 2002The authors describe an experimental hardware system used to estimate the angles of arrival of multiple cochannel emitters. The system consists of a four-element phased array antenna and a personal computer housing four coherentized digital receivers.

Angle of arrival estimation of on-body channels
2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007Angle of arrival (AoA) estimation has been performed on five on-body channels, namely belt-to-chest, belt-to-wrist, belt-to-ankle, belt-to-head and belt-to-back. The transmitter was always placed on the belt whilst the receiver was located on the points mentioned above. A quarter wavelength monopole and a switched beam array were used, respectively, as

An alternative approach for angle of arrival estimation
The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014The Multiple Signals Classification (MUSIC) algorithm is the most popular algorithm for estimating the Angle of Arrival (AOA) of the received signals. This algorithm is based on the calculation of thermal noise Eigenvalues and the corresponding Eigen vectors. All researches in this field assumed isotropic sensors to form the array antennas.

ESPRIT Angles-of-Arrival Estimation with Missing Sensor Data
2019 27th European Signal Processing Conference (EUSIPCO), 2019This paper describes a procedure for Angles-of-Arrival (AoA) estimation for a uniform linear array (ULA) with missing sensors. The novelty of the approach is that, rather than using AoA estimates obtained from contiguous subarrays, we use estimates for the corresponding signal subspaces.

Online angle of arrival estimation in the presence of mutual coupling
2016 IEEE Statistical Signal Processing Workshop (SSP), 2016A novel algorithm for estimating the Angles of Arrival (AoA) of multiple sources in the presence of mutual coupling is derived. We first formulate an “Equality Constrained Quadratic Optimisation” problem, then derive a suitable MUSIC-like algorithm to solve the aforementioned problem, and thus obtain good estimates of the AoA parameters ...

Positioning Based on 2-D Angle of Arrival Estimation
2011 IEEE 73rd Vehicular Technology Conference (VTC Spring), 2011We study the problem of determining the position of a node via the exploitation of 2-D angle of arrival estimation (azimuth and elevation), using orthogonal linear arrays. We also consider the presence of hardware impairments that include RF carrier frequency, phase, and DC offsets.
