    • Measuring the physical layer performance of wireless communication systems: Part 33 in a series of tutorials on instrumentation and measurement 

      Caban, Sebastian; García-Naya, José A.; Rupp, Markus (Institute of Electrical and Electronics Engineers & Instrumentation and Measurement Society, 2011-10)
      [Abstract]: Measuring the physical layer performance of wireless radio communication systems is one important step in clearly understanding their behavior in real-world, that is, non-simulation, environments. Unfortunately, ...

    • Equalizers in mobile communications: Tutorial 38 

      Rupp, Markus; García-Naya, José A. (Institute of Electrical and Electronics Engineers & Instrumentation and Measurement Society, 2012-06)
      [Abstract]: Modern cellular wireless systems would not be possible without high-performance equalizers. Signal impairments introduced by the wireless channel can only be compensated for by using such equalizers. This ...

    • Broadband Access in Complex Environments: LTE on Railway 

      Briso-Rodríguez, Cesar; López, Carlos F.; Fernández, Jean Raphaël Olivier; Pérez Jiménez, Sergio; Draskovic, Drasko; Calle-Sánchez, Jaime; Alonso Montes, José Ignacio; Rodríguez, Carlos; Hernández, Carlos; Molina-García, Mariano; moreno garcia-loygorri, Juan; Rodríguez Piñeiro, José; García-Naya, José A.; Castedo, Luis; Fernandez-Durán, Alfonso (Institute of Electronics, Information and Communication Engineers, 2014)
      [Abstract]: This paper assesses the main challenges associated with the propagation and channel modeling of broadband radio systems in a complex environment of high speed and metropolitan railways. These challenges comprise ...

    • Experimental evaluation of the WiMAX downlink physical layer in high-mobility scenarios 

      Suárez-Casal, Pedro; Rodríguez Piñeiro, José; García-Naya, José A.; Castedo, Luis (SpringerOpen & European Association for Signal Processing, 2015)
      [Abstract]: The experimental evaluation of the WiMAX downlink physical layer in high-mobility scenarios is extremely difficult to carry out because it requires the realization of measurement campaigns with expensive ...

    • 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 ...
