    • 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 ...

    • Advanced Coding and Signal Processing Methods for Multiuser MIMO Systems 

      Pérez-Adán, Darian (2022)
      [Resumo] Os sistemas de comunicacións sen fíos están a experimentar un crecemento constante nos últimos anos e agárdase que crezan aínda máis nos próximos anos axudados polo uso de novas técnicas de codificación e procesamento ...

    • Alternating Minimization for Wideband Multiuser IRS-Aided MIMO Systems Under Imperfect CSI 

      Pérez-Adán, Darian; Joham, Michael; Fresnedo, Óscar; González-Coma, José P.; Castedo, Luis; Utschick, Wolfgang (Institute of Electrical and Electronics Engineers, 2023-11-28)
      [Abstract]: This work focuses on wideband intelligent reflecting surface (IRS)-aided multiuser MIMO systems. One of the major challenges of this scenario is the joint design of the frequency-dependent base station (BS) ...

    • Deep Contextual Bandit and Reinforcement Learning for IRS-Assisted MU-MIMO Systems 

      Pereira-Ruisánchez, Dariel; Fresnedo, Óscar; Pérez-Adán, Darian; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2023-07)
      [Abstract]: The combination of multiple-input multiple-output (MIMO) systems and intelligent reflecting surfaces (IRSs) is foreseen as a critical enabler of beyond 5G (B5G) and 6G. In this work, two different approaches ...

    • Eavesdropping and Jamming via Pilot Attacks in 5G Massive MIMO 

      Angoue Avele, Marc Bernice; Pérez-Adán, Darian; Pereira-Ruisánchez, Dariel (Universidade da Coruña, Servizo de Publicacións, 2023)
      [Abstract] In thiswork, we investigate pilot attacks for 5G single-cell multi-user massive multipleinput multiple-output (MaMIMO) systems with a single-antenna active eavesdropper and a single-antenna jammer operating ...

    • Intelligent Reflective Surfaces for Wireless Networks: An Overview of Applications, Approached Issues, and Open Problems 

      Pérez-Adán, Darian; Fresnedo, Óscar; González-Coma, José P.; Castedo, Luis (MDPI, 2021)
      [Abstract] An intelligent reflective surface (IRS) is a novel and revolutionizing communication technology destined to enable the control of the radio environment. An IRS is a real-time controllable reflectarray with a ...

    • Lattice-Based Analog Mappings for Low-Latency Wireless Sensor Networks 

      Suárez-Casal, Pedro; Fresnedo, Óscar; Pérez-Adán, Darian; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2023-10-01)
      [Abstract]: We consider the transmission of spatially correlated analog information in a wireless sensor network (WSN) through fading single-input and multiple-output (SIMO) multiple access channels (MACs) with low-latency ...

    • User Grouping for the Uplink of Multiuser Hybrid mmWave MIMO 

      Pérez-Adán, Darian; Fresnedo, Óscar; González-Coma, José P.; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2020-03-16)
      [Abstract] Hybrid analog/digital schemes for precoding/combining have proved to be a low-complexity and/or low-power strategy to obtain reasonable beamforming gains in multiuser millimeter-wave (mmWave) multiple-input ...

    • Wideband User Grouping for Uplink Multiuser mmWave MIMO Systems With Hybrid Combining 

      Pérez-Adán, Darian; Fresnedo, Óscar; González-Coma, José P.; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2021-03-10)
      [Abstract] Analog-digital hybrid precoding and combining schemes constitute an interesting approach to millimeter-wave (mmWave) multiple-input multiple-output (MIMO) systems due to the low hardware complexity and/or low ...
