Source Localization with Intelligent Surfaces
ICC 2022 - IEEE International Conference on Communications, 2022Source localization is essential for a wide range of applications. The efficiency of source localization in complex wireless environments can be improved via the use of reconfigurable intelligent surfaces (RISs). In this paper, we investigate the information inequality of RIS-aided localization systems.

Source localization and beamforming
IEEE Signal Processing Magazine, 2002Distributed sensor networks have been proposed for a wide range of applications. The main purpose of a sensor network is to monitor an area, including detecting, identifying, localizing, and tracking one or more objects of interest. These networks may be used by the military in surveillance, reconnaissance, and combat scenarios or around the perimeter ...

Auditory localization of nearby sources. II. Localization of a broadband source
The Journal of the Acoustical Society of America, 1999Although many researchers have examined auditory localization for relatively distant sound sources, little is known about the spatial perception of nearby sources. In the region within 1 m of a listener’s head, defined as the “proximal region,” the interaural level difference increases dramatically as the source approaches the head, while the ...

Chemical Plume Source Localization
IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2006This paper addresses the problem of estimating a likelihood map for the location of the source of a chemical plume using an autonomous vehicle as a sensor probe in a fluid flow. The fluid flow is assumed to have a high Reynolds number. Therefore, the dispersion of the chemical is dominated by turbulence, resulting in an intermittent chemical signal ...

Since the discovery of electroencephalography (EEG), when it was hoped that EEG would offer "a window into the brain," researchers and clinicians have attempted to localize the neuronal activity in the brain that generates the scalp potentials measured noninvasively with EEG.

Source Localization with Feedback Beamforming
IEEE Transactions on Signal Processing, 2021State-of-the-art array processing methods, ranging from high-order statistics to adaptive configuration, require costly computing efforts in pursuit for spatial performance improvement. A feedback based approach is introduced in the context of localization, featuring low complexity and high spatial performance in the excess of integrating a transmitter

Electric source localization of the auditory P300 agrees with magnetic source localization
Electroencephalography and Clinical Neurophysiology/Evoked Potentials Section, 1995The event-related cortical potential elicited in the context of auditory target detection tasks includes the N1, P2 and P3 components. The aim of the present study was to identify the sources of these scalp-recorded components using an electrical multiple dipole model. Nine healthy adults volunteered for the study. An auditory oddball paradigm was used.

A deconvolution approach to source localization
IEEE Transactions on Signal Processing, 1993Because of its low resolution the conventional beamformer (CBF) has generally been neglected in the recent literature on array processing and considerable attention has been devoted to high-resolution (HR) techniques. A deconvolution approach was applied to the output of the CBF in order to obtain a source localization procedure whose performance is ...

Source Localization With Isotropic Arrays
IEEE Signal Processing Letters, 2004We consider the effect of unknown signal propagation velocity on direction-of-arrival (DOA) estimation performance using an array of sensors. For general arrays, the DOA estimation variance, as measured by the Crame/spl acute/r-Rao bound (CRB), degrades when the propagation velocity is unknown.

On multiple-parameter source localization
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002Localization of multiple-parameter sources is considered in this paper. Specifically, the problem of localizing EEG polarized sources is addressed. Expressions are presented for the variance of the source parameter estimates for the MUSIC estimator. The expressions are presented for both finite sample effects and the model perturbations effects.
