• openAccess   A pipeline structure for the block QR update in digital signal processing 

      Dolz, Manuel F.; Alventosa, Fran J.; Alonso-Jordá, Pedro Springer (2019-03)
      There exist problems in the field of digital signal processing, such as filtering of acoustic signals that require processing a large amount of data in real time. The beamforming algorithm, for instance, is a process that ...
    • closedAccess   Fast block QR update in digital signal processing 

      Alventosa, Fran J.; Alonso-Jordá, Pedro; Vidal, Antonio M.; Piñero, Gema; Quintana-Orti, Enrique S. Springer (2019-03)
      The processing of digital sound signals often requires the computation of the QR factorization of a rectangular system matrix. However, sometimes, only a given (and probably small) part of the system matrix varies from the ...
