    • Analogue joint source-channel coding for multiple input multiple output–orthogonal frequency division multiplexing systems 

      Fresnedo, Óscar; Vázquez-Araújo, Francisco J.; Castedo, Luis; Garcia-Frias, Javier (Wiley, 2016)
      [Abstract]: Analogue joint source-channel coding (JSCC) has been shown to approach the optimal distortion-cost trade-off when transmitting over additive white Gaussian noise channels. In this work, we consider analogue ...

    • Channel Estimation and Hybrid Precoding for Frequency Selective Multiuser mmWave MIMO Systems 

      González-Coma, José P.; Rodríguez-Fernández, Javier; Gonzalez-Prelcic, Nuria; Castedo, Luis; Heath, Robert W. (IEEE, 2018-05)
      [Abstract]: Configuring the hybrid precoders and combiners in a millimeter wave multiuser multiple-input multiple-output system is challenging in frequency selective channels. In this paper, we develop a system that uses ...

    • Emulating extreme velocities of mobile LTE receivers in the downlink 

      Rodríguez Piñeiro, José; Lerch, Martin; García-Naya, José A.; Caban, Sebastian; Rupp, Markus; Castedo, Luis (SpringerOpen & European Association for Signal Processing, 2015)
      [Abstract]: Long-Term Evolution (LTE) is expected to substitute the Global System for Mobile (GSM) Communications as the radio access technology for railway communications. Recently, considerable attention has been devoted ...

    • Experimental Evaluation of Flexible Duplexing in Multi-Tier MIMO Networks 

      Fanjul, Jacobo; Fernández, Renzo D.; Ibáñez, Jesús; García-Naya, José A.; Santamaría, Ignacio (SpringerOpen, 2020-09-24)
      [Abstract] In this paper, we present an experimental evaluation of the performance benefits provided by flexible duplexing, an access technique that allows uplink and downlink cells to coexist within the same time-frequency ...

    • Experimental evaluation of interference alignment for broadband WLAN systems 

      Lameiro, Christian; González Fernández, Óscar; García-Naya, José A.; Santamaría, Ignacio; Castedo, Luis (SpringerOpen & European Association for Signal Processing, 2015)
      [Abstract]: In this paper, we present an experimental study on the performance of spatial interference alignment (IA) in indoor wireless local area network scenarios that use orthogonal frequency division multiplexing ...
