    • A Deep Learning-Based Strategy to Predict Self-Interference in SFN DTT 

      Pereira-Ruisánchez, Dariel; Pérez-Adán, Darian; Castedo, Luis (MDPI, 2021)
      [Abstract] A deep learning-based strategy for the analysis of the self-interference in single frequency networks (SFNs) for digital terrestrial television (DTT) broadcasting is considered. Several laboratory measurements ...

    • Alternatives for Locating People Using Cameras and Embedded AI Accelerators: A Practical Approach 

      Carro Lagoa, Ángel; Barral Vales, Valentín; González-López, Miguel; Escudero, Carlos J.; Castedo, Luis (MDPI, 2021)
      [Abstract] Indoor positioning systems usually rely on RF-based devices that should be carried by the targets, which is non-viable in certain use cases. Recent advances in AI have increased the reliability of person detection ...

    • Analog Video Encoding and Quality Evaluation 

      Balsa, José; Fresnedo, Óscar; García-Naya, José A.; Domínguez-Bolaño, Tomás; Castedo, Luis (M D P I AG, 2019-07-23)
      [Abstract] The most widespread analog video encoding systems in the literature are based on the use of the 2D and 3D DCT. These systems use both transformations indistinctly without assessing their suitability. In this ...

    • Analysis, Design and Empirical Validation of a Smart Campus Based on LoRaWAN 

      Fraga-Lamas, Paula; Celaya-Echarri, Mikel; López Iturri, Peio; Fernández-Caramés, Tiago M.; Azpilicueta, Leyre; Aguirre, Erik; Suárez-Albela, Manuel; Falcone, Francisco; Castedo, Luis (MDPI, 2019)
      [Abstract] Internet of Things (IoT) applications for smart environments demand challenging requirements for wireless networks in terms of security, coverage, availability, power consumption, and scalability. The technologies ...

    • 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 ...

    • Evolving military broadband wireless communication systems: WiMAX, LTE and WLAN 

      Fraga-Lamas, Paula; Castedo, Luis; Morales-Méndez, Antonio; Camas-Albar, J. M. (Institute of Electrical and Electronics Engineers, 2016)
      [Abstract]: Emerging technologies for mobile broadband wireless are being considered as a Commercial Off-The-Shelf solution to cover the operational requirements of the future warfare. The capabilities of these technologies ...

    • Image Transmission: Analog or Digital? 

      Balsa González, José Francisco; Domínguez-Bolaño, Tomás; Fresnedo, Óscar; García-Naya, José A.; Castedo, Luis (M D P I AG, 2018-09-18)
      [Abstract] Evaluation and comparison of analog and digital wireless transmission systems.

    • Numerical Model of a 28-GHz Frequency Diverse Array Antenna 

      Angoue Avele, Marc Bernice; Brégains, Julio; Maneiro-Catoira, Roberto; García-Naya, José A.; Castedo, Luis (MDPI AG, 2020-08-22)
      [Abstract] In this work we make use of the frequency diverse array (FDA) concept, whose design is based upon a frequency increment across the antenna elements to generate a beam steering that is a function of angle, time ...

    • Real-time validation of a SDR implementation of TDD WiMAX standard 

      Carro Lagoa, Ángel; Suárez-Casal, Pedro; Fraga-Lamas, Paula; García-Naya, José A.; Castedo, Luis; Morales-Méndez, Antonio (The Wireless Innovation Forum, 2013)
      [Abstract]: This paper focuses on the validation of an innovative software- defined radio architecture for a WiMAX system based on commercially available field-programmable gate array and digital signal processor modules. ...

    • Unleashing the Potential of LTE for Next Generation Railway Communications 

      Fraga-Lamas, Paula; Rodríguez Piñeiro, José; García-Naya, José A.; Castedo, Luis (Springer, 2015)
      [Abstract]: In an increasingly demanding marketplace that will put great strain on railway services, research on broadband wireless communication must continue to strive for improvement. Based on the mature narrowband GSM ...
