Direction-of-arrival (DOA) estimation is the preliminary stage of communication, localization,
and sensing. Hence, it is a canonical task for next-generation wireless communications …

Two-dimensional (2D) arrays are fundamental to localization applications. Specifically,
sparse arrays can provide superior direction-of-arrival (DoA) estimation performance with …

Indoor positioning is one of the core technologies of Internet of Things (IoT) and artificial
intelligence (AI) and is expected to play a significant role in the upcoming era of AI …

The problem of locating signals transmitted in the proximity of an antenna array has been
studied extensively in the signal processing literature. In this paper, we consider the …

The problem of passive localization of mixed near-field (NF) and far-field (FF) source signals
in the presence of array gain-phase uncertainties is addressed. A new algorithm is aimed to …

Conventionally, mixed near-field (NF) and far-field (FF) source localization is performed
using a symmetric uniform linear array (ULA). Recently, two symmetric nonuniform linear …

Nested arrays have recently attracted a growing concern owing to their ability of achieving
extended aperture and enhanced degrees of freedom (DOFs) compared to conventional …
