    • Bandwidth assignment criteria against rayleigh backscattering effect in TDM-PON single-fibre wavelength-reuse networks 

      López Pastor, Eduardo Tommy; Lázaro Villa, José Antonio; Polo Querol, Víctor; Prat Gomà, Josep Joan (IEEE, 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      In this paper, theoretical and numerical analysis for Rayleigh Backscattering (RB) in TDM-PON full-duplex single-fiber bidirectional transmission with burst mode upstream and reflective ONU are presented. The results show ...

    • Modified duobinary polarization-shift keying transmission scheme 

      Gené Bernaus, Joan M.; Soler Rocasalbas, Marçal; Contreras Leyva, Miguel A.; Comellas Colomé, Jaume; Prat Gomà, Josep Joan (2003)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      A new version of duobinary polarization-shift keying scheme is proposed. The relocation of the duobinary filter at the receiver side and the optimization of both transmitter and receiver electrical filters offer a receiver ...

    • Optimal MISO pre-equalization for filter bank multicarrier systems 

      Caus López, Marius; Pérez Neira, Ana Isabel (2009)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      One of the phenomena that degrades the performance of multicarrier modulation (MCM) systems is the spectral nulls that multipath channel may have. As a result, the affected subcarrier signals may be severely degraded ...

    • Techno-economics of resilient extended FTTH PONs 

      Prat Gomà, Josep Joan; Lázaro Villa, José Antonio; Chatzi, Sotiria; Tomkos, Ioannis (IEEE, 2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This work analyses different architectures of protected FTTH passive optical networks in terms of device and infrastructure requirements and costs, considering different home density scenarios and volume projections. The ...
