    • Rank Constrained Precoding for the Downlink of mmWave Massive MIMO Hybrid Systems 

      González-Coma, José P.; Fresnedo, Óscar; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2021-02-11)
      [Abstract] The hybrid design of precoding schemes for millimeter-wave communications allows exploiting the gains by using large antenna array with an affordable hardware cost and power consumption. In this work, we present ...

    • 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 ...
