This article presents a novel application of the t-distributed Stochastic Neighbor Embedding
(t-SNE) clustering algorithm to the telecommunication field. t-SNE is a dimensionality …

Millimeter-wave (mm-wave) and subterahertz (sub-THz) technologies have attracted
considerable research interest because of their potential to fulfill the dramatically increased …

This paper presents a general technique for the joint Direction-of-Arrival (DoA) and Time-of-
Arrival (ToA) estimation in multipath environments. The proposed ultra-wideband technique …

In this paper, we present an analytical framework for the joint characterization of the 3D
direction of arrival (DoA), ie, azimuth and elevation components, and time of arrival (ToA) in …

This paper presents the dimensionality reduction of a propagation channel dataset created
through a measurement campaign. The scenario knowledge is essential for the signal …

In this paper, we present a phase-mode method for the estimation of time-of-arrival (ToA)
and direction-of-arrival (DoA) in smart wireless channels via concentric elliptical arrays with …

Distributed MIMO (D-MIMO) systems are expected to play a key role in deployments for
future mobile communications. Together with massive MIMO technology, D-MIMO aims to …

This paper presents the applicability of using the time-gating technique to propagation
measurements in order to recreate new scenarios. This technique, which has been studied …

This work presents the design of a broadband frequencyselective surface absorber (FSSA)
using laser-induced graphene (LIG). This type of resistive material composed of porous …

This paper describes the process followed to implement a system to characterize the
complex permittivity of materials in the 10-330 GHz frequency band. Firstly, the method used …
