    ESA’s Soil Moisture and Ocean Salinity (SMOS) mission was launched 2 Nov 2009 and, to date, is still in good health, providing valuable L-band observations of the Earth surface [1]. A number of products are obtained from ...
  • Motional behavior estimation using simple spectral estimation: application to the off-shore wind lidar 

    Salcedo Bosch, Andreu; Rocadenbosch Burillo, Francisco; Gutiérrez Antuñano, Miguel Ángel; Tiana Alsina, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    This paper proposes two methods to estimate the so-called “characteristic motional period” of a floating wind-lidar buoy. These techniques aim to characterise the buoy's pitch and roll tilting as simple harmonic motions ...
  • Floating Doppler Wind Lidar measurement of wind turbulence: a cluster analysis 

    Salcedo Bosch, Andreu; Gutiérrez Antuñano, Miguel Ángel; Tiana Alsina, Jordi; Rocadenbosch Burillo, Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    The standard deviation of the Horizontal Wind Speed as a proxy of wind turbulence is used to compare the apparent wind turbulence measured by an off-shore floating Doppler lidar to the one measured by a fixed lidar on a ...
  • Offshore Doppler Wind LiDAR assessment of atmospheric stability 

    Silva, Marcos Paulo Araujo da; Salcedo Bosch, Andreu; Gutiérrez Antuñano, Miguel Ángel; Rocadenbosch Burillo, Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    This paper tackles atmospheric stability typing using a Zephyr™ 300 offshore Doppler Wind Lidar in the context of its progressive acceptance in the offshore wind-energy industry. The lidar-retrieved wind-shear exponent, ...
  • Modelling multi-vendor transponders performance and optimizing launch power 

    Mahajan, Ankush; Christodoulopoulos, Konstantinos; Martínez Rivera, Ricardo Victor; Spadaro, Salvatore; Muñoz González, Raül (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    We propose physical layer model extensions that capture the performance variations of multivendor transponders and use those with appropriate algorithms to optimize connections’ launch powers. We estimated potential SNR ...
  • Filter features extraction from optical spectra 

    Locatelli, Fabiano; Christodoulopoulos, Kostantinos; Fàbrega Sánchez, Josep Maria; Svaluto Moreolo, Michela; Nadal Reixats, Laia; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    We propose a method to estimate the central frequency and the bandwidth of optical filters, that relies on optical spectra captured with optical channel monitors at ROADM’s ingress port. We demonstrate for both features ...
  • Analysis of service blocking reduction strategies in capacity-limited disaggregated datacenters 

    Pagès Cruz, Albert; Agraz Bujan, Fernando; Spadaro, Salvatore (2020)
    Conference report
    Restricted access - publisher's policy
    Disaggregated DCs offer multiple benefits. However, transmission capacity limitations at blade level can severely degrade their performance. We analyze several strategies to enhance their service acceptance.
  • Design and digital predistortion linearization of a wideband outphasing amplifier supporting 200 MHz bandwidth 

    Gilabert Pinal, Pere Lluís; Vegas, David; Ren, Zhixiong; Montoro López, Gabriel; Pérez-Cisneros, José Ramón; Ruiz, Nieves; Si, Xiaoshu; García García, José Ángel (2020)
    Conference report
    Open Access
    This paper presents a holistic approach to design and linearize a wideband outphasing power amplifier (PA) to efficiently amplify a 200 MHz bandwidth (BW) signal compliant with the Data Over Cable Service Interface ...
  • Continuous multi-objective zero-touch network slicing via twin delayed DDPG and OpenAI gym 

    Rezazadeh, Farhad; Chergui, Hatim; Alonso Zárate, Luis Gonzaga; Verikoukis, Christos (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference lecture
    Restricted access - publisher's policy
    Artificial intelligence (AI)-driven zero-touch network slicing (NS) is a new paradigm enabling the automation of resource management and orchestration (MANO) in multi-tenant beyond 5G (B5G) networks. In this paper, we ...
  • Antenna packaging for in-body applications 

    Romeu Robert, Jordi; González López, Giselle; Blanch Boris, Sebastián; Jofre Roca, Lluís (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    A cylindrical mode expansion of the fields produced by an embedded antenna is used to determine the dimensions of the antenna packaging in order to minimize antenna impedance changes when the antenna is immersed in a varying ...
  • Using spatial division multiplexing to avoid fragmentation in flex-grid optical networks 

    Comellas Colomé, Jaume; Perelló Muntan, Jordi; Solé Pareta, Josep; Junyent Giralt, Gabriel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    Spectrum fragmentation is one of the main drawbacks of Flex-Grid Optical Networks, and it becomes especially harmful under dynamic traffic conditions. When evolving from single fibre networks to spatial division multiplexed ...
