High-resolution parameter estimation algorithms designed to exploit the prior knowledge
about incident signals from strictly second-order (SO) noncircular (NC) sources allow for a …

Channel estimation is challenging for hybrid millimeter wave (mmWave) large-scale
antenna arrays which are promising in 5G/B5G applications. The challenges are associated …

A structured least squares (SLS)-based ESPRIT algorithm for direction-of-arrival (DOA)
estimation of strictly second-order noncircular signals using a crossed array is devised in …

In this paper, we perform asymptotic analyses of the widely used ESPRIT direction-of-arrival
(DoA) estimator for large arrays, where the array size $ N $ and the number of snapshots $ T …

An ambiguity-free direction of arrival (DOA) estimation method is presented for unfolded
coprime linear array (UCLA) in this paper to resolve noncircular signals. Unlike the existing …

Recently, direction of arrival (DOA) estimation for non-circular (NC) sources has attracted
great attention in array signal processing since NC signals can provide more information to …

Adaptive generalized sidelobe cancelers (GSCs) have been widely used to enhance the
desired signal and instantaneously suppress interference signal and noise. However, the …

In this paper, a novel noncircularity-based localization method for mixed near-field (NF) and
far-field (FF) sources is proposed with a symmetric uniform linear array (ULA) in the …

We investigate the issue of direction of arrival (DOA) estimation of noncircular signals for
coprime linear array (CLA). The noncircular property enhances the degree of freedom and …

This paper presents a cumulant-based algorithm for near-field noncircular sources
localization with a symmetric uniform linear array. It first constructs three extended matrices …
