Thinned coprime arrays for DOA estimation [PDF]
, 2017 Sparse arrays can generate a larger aperture than traditional uniform linear arrays (ULA) and offer enhanced degrees-of-freedom (DOFs) which can be exploited in both beamforming and direction-of-arrival (DOA) estimation. One class of sparse arrays is the

A Super Augmented Nested Array With L‐Shaped Geometry for Enhanced Two‐Dimensional DOA Estimation
IET Signal Processing, Volume 2026, Issue 1, 2026.This study proposes an L‐shaped super augmented nested array (LSANA) structure for two‐dimensional (2‐D) direction of arrival (DOA) estimation. The proposed LSANA structure consists of two linear arrays located along the x‐axis and y‐axis, respectively.

Least Order Coprime Factorizations of Rational Matrices: The Canonical Case [PDF]
, 1998 Given an arbitrary real rational matrix G and a domain Gamma g in the closed complex plane we develop a complete theory of coprime factorizations of G over Gamma g having denominators of least possible McMillan degree.

A Hole-free Shifted Coprime Array for DOA Estimation [PDF]
Coprime arrays have recently become a popular trend in estimating the direction of arrival in array signal processing, as they increase the degree of freedom (DOF).

The dimension of well approximable numbers
Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.Abstract In this survey article, we explore a central theme in Diophantine approximation inspired by a celebrated result of Besicovitch on the Hausdorff dimension of well approximable real numbers. We outline some of the key developments stemming from Besicovitch's result, with a focus on the mass transference principle, ubiquity and Diophantine ...

Delay Coprime Array: A New Sparse Linear Array for Fast and Robust DOA Estimation [PDF]
In this letter, we propose a new sparse linear array (SLA), termed delay coprime array (DCA), and correspondingly develop a low-complexity direction of arrival (DOA) estimation algorithm.

A note on the coprime graph of a group [PDF]
, 2016 In this paper we study the coprime graph of a group $G$. The coprime graph of a group $G$, is a graph whose vertices are elements of $G$ and two distinct vertices $x$ and $y$ are adjacent iff $(|x|,|y|)=1$.

Direction-of-Arrival Estimation in Coprime Array Using the ESPRIT-Based Method
, 2019 Coprime arrays have shown potential advantages for direction-of-arrival (DOA) estimation by increasing the number of degrees-of-freedom in the difference coarray domain with fewer physical sensors.
