2D-Unitary ESPRIT Based Multi-Target Joint Range and Velocity Estimation Algorithm for FMCW Radar
Applied Sciences, 2023 Millimeter-wave FMCW radar has been widely used in joint range-velocity estimation of multiple targets. However, most existing algorithms are unable to estimate the range-velocity information with high accuracy simultaneously and fail to discriminate the

Acta 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 ...

ESPRIT-Forest: Parallel clustering of massive amplicon sequence data in subquadratic time. [PDF]
PLoS Computational Biology, 2017 The rapid development of sequencing technology has led to an explosive accumulation of genomic sequence data. Clustering is often the first step to perform in sequence analysis, and hierarchical clustering is one of the most commonly used approaches for ...

Sparse graph signals – uncertainty principles and recovery
GAMM-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.

Blind Direction-of-Arrival Estimation with Uniform Circular Array in Presence of Mutual Coupling
International Journal of Antennas and Propagation, 2016 A blind direction-of-arrival (DOA) estimation algorithm based on the estimation of signal parameters via rotational invariance techniques (ESPRIT) is proposed for a uniform circular array (UCA) when strong electromagnetic mutual coupling is present ...

Joint DOD and DOA Estimation in Bistatic MIMO Radar With Distributed Nested Arrays
IEEE Access, 2019 In this paper, we investigate the problem of joint direction of departure (DOD) and the direction of arrival (DOA) estimation in bistatic MIMO radar. A new bistatic MIMO radar with the distributed nested array is proposed. Based on the new array, the DOD

Accounting Perspectives, Volume 24, Issue 2, Page 343-391, June 2025.ABSTRACT Compared to large enterprises (LEs), small and medium‐sized enterprises (SMEs) have unique characteristics that may affect their needs in several areas. Thus, the “one‐size‐fits‐all” approach to meeting the needs of both groups of enterprises would be inappropriate in different circumstances.

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