Photonic millimeter-wave bridge for multi-Gbps passive optical networks
(Elsevier B.V., 2018-06-01)
Survivability is a critical requirement of optical communication networks that is typically addressed implementing path diversity. However, due to the elevated cost of fiber installation, this approach may prove prohibitively ...
Shadowing Correlation: Empirical Results for mm-Wave Wireless Links in Urban Street Canyons
(2018)
To the best of our knowledge, this letter reports the first measurement campaign aimed at modeling the empirical large-scale/shadowing decorrelation distance in urban street canyons at 60 GHz. The observed path-loss exponents ...
Impact of the mobile terminal scheme on millimeter-wave radio over fiber systems based on photonic heterodyning techniques
(2017-06-01)
The use of communication networks relying on millimeter-wave (mm-wave) wireless links promises a great capacity enhancement as well as improved security. However, given the high-directivity of mm-wave links, coverage ...
5G MIMO and LIDAR data for machine learning: mmWave beam-selection using deep learningDados 5G MIMO e LIDAR para aprendizado de máquina: seleção de feixe mmWave usando aprendizagem profunda
(Universidade Federal do ParáBrasilInstituto de TecnologiaUFPAPrograma de Pós-Graduação em Engenharia Elétrica, 2019)
Application of evolutionary computation techniques in emerging optimization problems in 5G and beyond wireless systems
(2021)
Os sistemas comunicação sem fio 5G e além (B5G, do inglês Beyong 5G) permitirão a plena implantação de aplicações existentes, como carros autônomos, redes de sensores massivas e casas inteligentes. Para tornar essas ...
Optimizing Spectral Efficiency with Massive MIMO Systems for 5G NR Mobile Networks
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-12)
The fifth-generation (5G) of mobile communications defines two main operating bands: The frequency band below 6 GHz (sub-6 GHz), where the pilot contamination phenomenon limits the spectral efficiency, and the millimeter-wave ...
Hidden Holocene Slip Along the Coastal El Yolki Fault in Central Chile and Its Possible Link With Megathrust Earthquakes
(2019)
Megathrust earthquakes are commonly accompanied by increased upper-plate seismicity and occasionally triggered fault slip. In Chile, crustal faults slipped during and after the 2010 Maule (M8.8) earthquake. We studied the ...
Cathodic stripping square-wave voltammetry for assessing As(III) removal with synthetic mixed oxides
(Springer, 2017-11)
The possibility of counting with a reliable and economic system for filtering large volumes of water contaminated with arsenic is highly desired since different species of this element conform a major health risk through ...
