Welcome

The Advanced Signal Processing Group (GTAS, in Spanish) is part of the Communications Engineering Department of the University of Cantabria. It is located at the E.T.S.I. Industriales y Telecomunicaciones, Avda Los Castros s/n. Santander 39005, SPAIN.

The GTAS conducts research in the development of digital signal processing algorithms for communications, as well as in machine-learning techniques, optimization, and nonlinear modeling. Currently, the research activity of the GTAS is focused on the following topics:

  • Signal processing techniques for wireless networks.
    • Advanced interference management techniques for multi-user MIMO systems (NOMA, rate-splitting, interference alignment, improper Gaussian signaling schemes, etc)
    • Detection and estimation in multi-sensor arrays.
    • Development of hardware MIMO testbeds and performance evaluation.
  • Machine-learning techniques and their applications.
    • Kernel methods, learning algorithms, and adaptive information processing systems.
    • Multivariate statistical techniques: PCA, CCA, and ICA.
    • Nonlinear modeling.
