Direction-of-arrival (DOA) estimation plays a crucial role in array signal processing across
various domains, including radar, sonar, wireless communications, and seismic exploration …

Tensor-based methods have attracted significant interest also in array signal processing
(ASP) given the inherently multi-dimensional nature of the problems involved therein. The …

The ability of tensor decomposition (TD)-based methods to recover latent information,
including channel parameters and transmitted symbols in the array signal processing (ASP) …

Large-aperture coprime arrays (CAs) are expected to achieve higher sensing resolution
than conventional dense arrays (DAs), yet with lower hardware and energy cost. However …

The localization of multiple signal sources using sensor arrays has been a long-standing
research challenge. While numerous solutions have been developed, signal space methods …

In this paper, a novel two-phase near-field localization method for the symmetric coprime
array is proposed which comprises two spare uniform linear arrays (ULAs). First, to extract …

A novel low-complexity wavenumber-domain method is proposed for near-field sensing
(NISE). Specifically, the power-concentrated region of the wavenumber-domain channels is …
