    • Channel Covariance Identification in FDD Massive MIMO Systems 

      González-Coma, José P.; Suárez-Casal, Pedro; Castro-Castro, Paula-María; Castedo, Luis; Joham, Michael (IEEE, 2018-11)
      [Abstract]: Many channel estimation methods in Massive MIMO FDD systems usually rely on the knowledge of the channel covariance matrix to operate. However, in real scenarios, this covariance is not known beforehand, and ...

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

      González-Coma, José P.; Suárez-Casal, Pedro; Castro-Castro, Paula-María; Castedo, Luis (M D P I AG, 2020-02-10)
      [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 ...

    • Virtual Sensor for Fault Detection, Isolation and Data Recovery for Bicomponent Mixing Machine Monitoring 

      Jove, Esteban; Casteleiro-Roca, José-Luis; Quintián, Héctor; Méndez Pérez, Juan Albino; Calvo-Rolle, José Luis (Vilnius University, 2019)
      [Abstract] The present research shows the implementation of a virtual sensor for fault detection with the feature of recovering data. The proposal was implemented over a bicomponent mixing machine used for the wind generator ...
