5G for construction: use cases and solutions
(MDPI, 2021)The world is currently undergoing a new industrial revolution characterized by the digitization and automation of industry through the use of Information and Communication Technologies (ICT). The construction sector is ... -
A Tractable Product Channel Model for Line-of-Sight Scenarios.
Fernández-Plazaola, Unai
; Moreno-Pozas, Laureano; López-Martínez, Francisco Javier; París-Ángel, José Francisco; Martos-Naya, Eduardo; Romero-Jerez, Juan Manuel[et al.] (IEEE, 2020-01-06)
We present a general and tractable fading model for line-of-sight (LOS) scenarios, which is based on the product of two independent and non-identically distributed κ-μ shadowed power envelopes. Simple closed-form expressions ... -
Analytical design of compact multiband bandpass filters with multiconductor transmission lines and shunt open stubs
Pérez-Escribano, Mario; Márquez-Segura, Enrique; Sánchez-Martínez, Juan José (MDPI, 2023-04-24)
A compact topology for implementing compact multiband bandpass filters is presented in this paper. To achieve the desired frequency response, two identical short-circuited multiconductor transmission lines (MTLs) and ... -
Analytical Framework to Model Reconfigurable Metasurfaces including Lumped Elements.
Pérez-Escribano, Mario; Moreno-Rodríguez, Salvador; Molero, Carlos; Valenzuela-Valdés, Juan Francisco; Padilla, Pablo; Alex-Amor, Antonio; Pérez-Escribano, Mario[et al.] (IEEE Transactions on Circuits and Systems II: Express Briefs, 2023-11-06)
This manuscript introduces an analytical framework for the design of reconfigurable metasurfaces rooted in 2D periodic structures. Incorporating lumped elements into the model streamlines the design process for such devices, ... -
Data mining for fuzzy diagnosis systems in LTE networks.
Jatib Khatib, Emil; Barco-Moreno, Raquel; Gómez-Andrades, Ana; Muñoz, Pablo; Serrano, Inmaculada (Elsevier, 2015-06-01)
The recent developments in cellular networks, along with the increase in services, users and the demand of high quality have raised the Operational Expenditure (OPEX). Self-Organizing Networks (SON) are the solution to ... -
Low-Complexity Distance-Based Scheduling for Multi-User XL-MIMO Systems.
(IEEE, 2021-08-02)We introduce Distance-Based Scheduling (DBS), a new technique for user selection in downlink multi-user communications with extra-large (XL) antenna arrays. DBS categorizes users according to their equivalent distance ... -
Multinode component carrier management: multiconnectivity in 5G
De la Bandera Cascales, Isabel; Palacios, David; Barco-Moreno, Raquel (IEEE, 2021)
From its conception, 5G has been designed to support a wide variety of service types, ranging from enhanced mobile broadband (eMBB) to ultra-reliable low-latency communications (URLLC). To overcome the disparity of their ... -
Optimization of 5G Networks for Smart Logistics.
Jatib Khatib, Emil; Barco-Moreno, Raquel (MDPI, 2021-03-22)
Industry 4.0 is generalizing the use of wireless connectivity in manufacturing and logistics. Specifically, in Smart Logistics, novel Industry 4.0 technologies are used to enable agile supply chains, with reduced management, ... -
Performance Evaluation of Broadband Characterization of Coupled Transmission Lines Even- and Odd-Mode Propagation Constants Using Differential and Common Mode S-Parameters
Pérez-Escribano, Mario; Márquez-Segura, Enrique (IEEE Journal of Microwaves, 2023)
This work encompasses some relevant issues that arise when using a broadband method to characterize the even and odd mode propagation constants of symmetric microstrip coupled lines using four-port pure-mode differential ... -
Reconfigurability mechanisms with scanning rate control for omega-bianisotropic Huygens’ metasurface leaky-wave antennas
Abdo-Sánchez, María Elena; Epstein, Ariel; Eleftheriades, George V. (IEEE, 2019)
In this paper, different reconfigurability mechanisms are proposed to scan the pointing direction at a fixed frequency of recently-proposed leaky-wave antennas based on omega-bianisotropic Huygens' metasurfaces. The ... -
Self-Healing Framework for Next-Generation Networks through Dimensionality Reduction.
Palacios, David; Fortes-Rodríguez, Sergio; De la Bandera Cascales, Isabel; Barco-Moreno, Raquel (IEEE, 2018-07-25)
Next generation self-organizing networks (NGSONs) are the key that will lead to the full automation of the network management in the forthcoming generations of cellular communications. New challenges, like the deployment of ... -
