Angle of arrival estimation of on-body channels
2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007 Angle 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

Estimation of angles-of-arrival for wideband sources
ICASSP '84. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005High 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, 2005A 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.

On the security of Angle of Arrival estimation
2016 IEEE Conference on Communications and Network Security (CNS), 2016Angle 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.

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 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 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.
