An ESPRIT Algorithm for Tracking Time-Varying Signals [PDF]

open access: yes, 1992
Abstract : ESPRIT is a successful algorithm for determining the constant directions of arrival of a set of narrowband signals on an array of sensors. Unfortunately, its computational burden makes it unsuitable for real time processing of signals with time-varying directions of arrival.

Perspectives on the Current and Future State of Artificial Intelligence in Medical Genetics

open access: yesAmerican Journal of Medical Genetics Part A, Volume 197, Issue 10, October 2025.
ABSTRACT Artificial intelligence (AI) is rapidly transforming numerous aspects of daily life, including clinical practice and biomedical research. In light of this rapid transformation, and in the context of medical genetics, we assembled a group of leaders in the field to respond to the question about how AI is affecting, and especially how AI will ...

Angle of Arrival Estimation Using Cholesky Decomposition

open access: yesInternational Journal of Antennas and Propagation, 2012
An angle of arrival (AOA) estimator is presented. Many applications require accurate AOA estimates such as wireless positioning and signal enhancement using space-processing techniques. The proposed AOA estimator depends on the Cholesky decomposition of

Multidisciplinary study of thorium mobility: formation of turkestanite and steacyite analogues, and structural insights using an XRD‐directed microcrystal preparation technique

open access: yesActa Crystallographica Section B, Volume 81, Issue 4, Page 418-426, August 2025.
A novel focused ion beam and scanning electron microscope‐based technique has been developed for mounting microcrystals on carbon fibre, making them immediately compatible with single‐crystal X‐ray diffraction. This method has been successfully applied to studying the crystal chemistry of a synthetic Th‐bearing, Na analogues of turkestanite and ...

Two-Dimensional Direction-of-Arrival Fast Estimation of Multiple Signals with Matrix Completion Theory in Coprime Planar Array

open access: yesSensors, 2018
In estimating the two-dimensional (2D) direction-of-arrival (DOA) using a coprime planar array, the main issues are the high complexity of spectral peak search and the limited degree of freedom imposed by the number of sensors.

Sparse graph signals – uncertainty principles and recovery

open access: yesGAMM-Mitteilungen, Volume 48, Issue 2, June 2025.
ABSTRACT We study signals that are sparse either on the vertices of a graph or in the graph spectral domain. Recent results on the algebraic properties of random integer matrices as well as on the boundedness of eigenvectors of random matrices imply two types of support size uncertainty principles for graph signals.

SVD filtering and TLS‐ESPRIT algorithm based on stator fault characteristic detection of doubly‐fed induction generator

open access: yesJurnal Engineering, 2019
This study proposes a novel method for detecting faults in the stator of the doubly-fed wind turbines based on the combination of singular value decomposition (SVD) filtering and least-squares parameter invariant signal technique (TLS-ESPRIT). The stator
