  • FDD Channel Estimation Via Covariance Estimation in Wideband Massive MIMO Systems 

    González-Coma, José P.; Suárez-Casal, Pedro; Castro, Paula M.; Castedo, Luis (M D P I AG, 2019-02-10)
    [Abstract] A method for channel estimation in wideband massive Multiple-Input Multiple-Output systems using hybrid digital analog architectures is developed. The proposed method is useful for Frequency-Division Duplex at ...
  • Power Efficient Scheduling and Hybrid Precoding for Time Modulated Arrays 

    González-Coma, José P.; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2020-01-22)
    [Abstract] We consider power efficient scheduling and precoding solutions for multiantenna hybrid digital-analog transmission systems that use Time-Modulated Arrays (TMAs) in the analog domain. TMAs perform beamforming ...
  • Towards Post-Quantum Blockchain: A Review on Blockchain Cryptography Resistant to Quantum Computing Attacks 

    Fernández-Caramés, Tiago M.; Fraga-Lamas, Paula (Institute of Electrical and Electronics Engineers, 2020-01-23)
    [Abstract] Blockchain and other Distributed Ledger Technologies (DLTs) have evolved significantly in the last years and their use has been suggested for numerous applications due to their ability to provide transparency, ...

  • New Computation of Resolving Connected Dominating Sets in Weighted Networks 

    Dapena, Adriana; Iglesia, Daniele; Vazquez-Araujo, Francisco J.; Castro, Paula M. (M D P I AG, 2019-11-29)
    [Abstract] In this paper we focus on the issue related to finding the resolving connected dominating sets (RCDSs) of a graph, denoted by G. The connected dominating set (CDS) is a connected subset of vertices of G selected ...
