      Para poder implementar un sistema de comunicaciones inalámbrico, los operadores necesitan evaluar cómo se caracteriza la propagación a través del canal radio. Esto permite conocer el impacto de las pérdidas sobre el servicio ...
    • Medidas de propagación sobre el mar a 900 MHz 

      Ferrando Bataller, Miquel (1998)
      Conference report
      Open Access
      In this article, propagation measurements over the sea in 900 MHz band are presented. Objective of these measurements is to have a set of real data for the study of radiowave propagation over the sea in this band.
    • Numerical simulation of long-path spherical wave propagation in three-dimensional random media 

      Rubio Sancho d'Ávila, Juan Antonio; Belmonte Molina, Aniceto; Comerón Tejero, Adolfo (SPIE-INT SOCIETY OPTICAL ENGINEERING, 1999-09-30)
      Article
      Open Access
      A new method to overcome some limitations in the simulation of the propagation of waves originating from a point source through a very long path in a turbulent medium is presented. Existing propagation simulation algorithms ...
    • Performance of 16 & 64 QAM digital radio systems with multipath propagation and distortion induced phase jitter 

      Olmos Bonafé, Juan José; Casadevall Palacio, Fernando José (Institute of Electrical and Electronics Engineers (IEEE), 1989)
      Conference report
      Restricted access - publisher's policy
      This paper presents a new method for assessing the bit error probability in a QAM system taking into account thermal noise, multipath distortion and phase Jitter. System signature is calculated for a system without any ...

    • Reconfigurable pixel-layer isolator for frequency-tunable on-frequency repeaters 

      Rodrigo López, Daniel; Díaz Tapia, Edgar; Jofre Roca, Lluís (2014)
      Article
      Restricted access - publisher's policy
      The maximum gain in on-frequency repeaters is limited by the isolation level between their two antennas due to close-loop stability conditions. In this letter, a novel pixel-layer isolator for tunable on-frequency repeaters ...
