    Article
    Open Access
    This paper presents a novel planar filtering antenna (filtenna) with simple layout based on tightly-coupled different-length monopoles. Its design methodology is based on an even-mode/odd-mode decomposition of the monopole ...
  • Asymptotic analysis of near-field coupling in massive MISO and massive SIMO systems 

    Martí Espelt, Aniol; Riba Sagarra, Jaume; Lamarca Orozco, M. Meritxell; Gràcia Sabaté, Francesc Xavier (2024-06-17)
    Article
    Open Access
    This paper studies the receiver to transmitter antenna coupling in near-field communications with massive arrays. Although most works in the literature consider that it is negligible and approximate it by zero, there is ...

    Vila Insa, Marc; Martí Espelt, Aniol; Riba Sagarra, Jaume; Lamarca Orozco, M. Meritxell (Institute of Electrical and Electronics Engineers (IEEE), 2024-06-14)
    Article
    Open Access
    With the goal of enabling ultrareliable and low-latency wireless communications for industrial internet of things (IIoT), this paper studies the use of energy-based modulations in noncoherent massive single-input multiple-output ...
  • Using convolutional neural networks for blocking prediction in elastic optical networks 

    Nourmohammadi, Farzaneh; Parmar, Chetan; Wings, Elmar; Comellas Colomé, Jaume (Multidisciplinary Digital Publishing Institute, 2024-02-28)
    Article
    Open Access
    This paper presents a study on connection-blocking prediction in Elastic Optical Networks (EONs) using Convolutional Neural Networks (CNNs). In EONs, connections are established and torn down dynamically to fulfill the ...
  • Remote sensing and its applications using GNSS reflected signals: advances and prospects 

    Jin, Shuanggen; Camps Carmona, Adriano José; Jia, Yan; Wang, Feng; Martín Neira, Manuel; Huang, Feixiong; Yan, Qingyun; Zhang, Shuangcheng; Li, Zhongyu; Edokossi, Komi; Yang, Dongkai; Xiao, Zhiyu; Ma, Zhongmin; Bai, Weihua (2024-05-27)
    Article
    Open Access
    The Global Navigation Satellite Systems (GNSS), including the US’s GPS, China’s BDS, the European Union’s Galileo, and Russia’s GLONASS, offer real-time, all-weather, any-time, anywhere and high precision observations by ...
  • Scattering mechanism analysis of large vertical cylindrical structure in polarimetric SAR images 

    Chen, Yifan; Zhang, Lamei; Mallorquí Franquet, Jordi Joan; Zou, Bin (Institute of Electrical and Electronics Engineers (IEEE), 2024-01-19)
    Article
    Open Access
    Large vertical cylindrical structure is an important type of structure in polarimetric synthetic aperture radar (PolSAR) images. Objects with this structure, such as oil tanks, granaries and rotor sails, attract much ...
