    • A proposal for an adaptive S-ALOHA access system for a mobile CDMA environment 

      Sallent Roig, Oriol; Agustí Comes, Ramon (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-08)
      Article
      Accés obert
      This paper presents a novel adaptive direct-sequence code-division multiple-access (DS-CDMA) slotted-ALOHA (S-ALOHA) packet random-access scheme with transmitter-based spreading codes for mobiles. It is aimed at improving ...

      Igual Bueno, Jordi (Universitat Politècnica de Catalunya, 2017-07-12)
      Treball Final de Grau
      Accés restringit per acord de confidencialitat
      Realitzat a/amb:   SINOTEC Engineering

    • Evaluación de la transmisión audiovisual en redes IP con aplicación de técnicas FEC 

      Dávila Linarez, Lluís (Universitat Politècnica de Catalunya, 2021-05-27)
      Treball Final de Grau
      Accés obert
      IP networks introduce errors in the multimedia content sent through them, therefore, to correct this error, said audiovisual content in MPEG4 format is protected by using error correction techniques such as Pro-MPEG, which ...

    • Experimental demonstration of multi-vendor and multi-domain elastic optical network with data and control interoperability over a pan-european test-bed 

      González de Dios, Oscar; Casellas Regi, Ramón; Paolucci, Francesco; Napoli, Antonio; Gifre Renom, Lluís; Dupas, Arnaud; Hugues Salas, Emilio; Morro, Roberto; Belotti, Sergio; Meloni, Gianluca; Rahman, Talha; López Álvarez, Victor; Martínez Rivera, Ricardo Victor; Fresi, Francesco; Bohn, Marc; Yan, Shuangyi; Velasco Esteban, Luis Domingo; Layec, Patricia; Fernández Palacios, Juan Pedro (2016-04-01)
      Article
      Accés obert
      The operation of multidomain and multivendor EONs can be achieved by interoperable sliceable bandwidth variable transponders (S-BVTs), a GMPLS/BGP-LS-based control plane, and a planning tool. The control plane is extended ...

    • Forward error correction in optical ethernet communications 

      Oliveras Boada, Jordi (Universitat Politècnica de Catalunya, 2014-07-21)
      Treball Final de Grau
      Accés obert
      [ANGLÈS] A way of incrementing the amount of information sent through an optical fibre is ud-WDM (ultra dense – Wavelength Division Multiplexing). The problem is that the sensitivity of the receiver requires certain SNR ...

    • Hybrid turbo FEC/ARQ systems and distributed space-time coding for cooperative transmission 

      Agustín de Dios, Adrián; Vidal Manzano, José; Muñoz Medina, Olga (2005-08-24)
      Article
      Accés obert
      Cooperative transmission can be seen as a "virtual" MIMO system, where the multiple transmit antennas are in fact implemented distributed by the antennas both at the source and the relay terminal. Depending on the system ...

    • IPTV via WIFI per la Televisió Local de Vallirana 

      Sellart Ortega, Xavier (Universitat Politècnica de Catalunya, 2008-06-27)
      Projecte/Treball Final de Carrera
      Accés obert
      Realitzat a/amb:   Televisió de Vallirana
      La raó per la qual va sorgir aquest projecte es degut a que amb l’arribada del TDT, les televisions locals hauran de compartir canal. Per això, es van buscar alternatives per continuar tenint un canal independent, i així ...

    • Software de gestió de dades per a nanosatèl·lits 

      Masip Vela, Albert (Universitat Politècnica de Catalunya, 2019-01-28)
      Treball Final de Grau
      Accés obert
      Tractament de les dades generades a bord d'un nanosatèl·lit perquè aquestes siguin enviades de manera robusta a terra.

    • Throughput efficiency in body sensor networks: a clean-slate approach 

      Domingo Aladrén, Mari Carmen (2012-08)
      Article
      Accés restringit per política de l'editorial
      In this paper, a flexible role-based architecture for Body Sensor Networks (BSNs) is introduced. The proposed non-layered context-aware architecture is application-oriented and able to incorporate future applications. ...
