The Steered Response Power – Phase Transform
(SRP-PHAT) algorithm has been shown to be one of the most robust
sound source localization approaches operating in noisy and
reverberant environments. However, its practical ...

[EN] Meeting the increasing demand for capacity in wireless networks requires the harnessing of higher regions in the radiofrequency spectrum, reducing cell size, as well as more compact, agile and power-efficient base ...
Betters, Christopher H.; Bland-Hawthorn, Joss; Sukkarieh, Salah; Gris-Sánchez, Itandehui; Leon-Saval, Sergio G.(Institute of Electrical and Electronics Engineers, 2020-04-01)
[EN] We report on the development of a compact (volume approximate to 100 cm(3)), multimode diffraction-limited Raman spectrograph and probe designed to be compact as possible. The spectrograph uses 'off the shelf' optics, ...
[EN] This work introduces a multisensor road surface identification system that considers features from four different kind of sensors: microphones, accelerometers, speed signals, and handwheel signals. Features are extracted ...
Melgarejo, Juan Carlos; Cogollos, Santiago; Guglielmi, Marco; Boria Esbert, Vicente Enrique(Institute of Electrical and Electronics Engineers, 2020-07)
[EN] In this article, we describe a new family of multiband waveguide filters based on a folded topology. The folded topology allows to use the filters of different orders and the introduction of transmission zeros. The ...
[EN] This paper presents a new method for fraud detection in credit cards based on exploiting the dynamics of the card transactions. We hypothesize different behavior models in the use of the card between legitimate clients ...

[EN] Multipactor (MP) is a high-power effect severely limiting the performance of satellite communication links. A reference sample is normally used in the experimental setups for MP testing in order to verify its correct ...
[EN] The essential step of surrogating algorithms is phase randomizing the Fourier transform while preserving the original spectrum amplitude before computing the inverse Fourier transform. In this paper, we propose a new ...
García-Navas, José Luis; Botella-Campos, Marta; Rego, Albert; Sendra, Sandra; Lloret, Jaime(Institute of Advanced Engineering and Science, 2021-12)
[EN] In this paper, a novel solution to avoid new infections is presented. Instead of tracing users¿ locations, the presence of individuals is detected by analysing the voices, and people¿s faces are detected by the camera. ...
[EN] A T-shaped slot-array antenna fed through a Groove
Gap Waveguide (GGW) is presented in this paper. The array
antenna operates at 30 GHz. The way the slots are excited,
along with the T-shape on its lid allows a compact ...

A novel wideband low-profile planar antenna design
based on the use of a high-impedance surface (HIS) is presented
for digital television (DTV) reception in the UHF band. The proposed
design is based on a wideband ...
[EN] In this paper, embedded coaxial substrate integrated waveguide (CSIW) filters with innovative magnetic couplings are presented and studied. By creating the loading capacitance of a combline topology using inner layers ...
