    Article
    Open Access
    3GPP standards organization is performing an impressive effort trying to reach sub-millisecond latencies for 5G. However, such efforts may become fruitless if exogenously generated delays at transport layer are not considered. ...

  • Superregeneration revisited: from principles to current applications 

    Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Águila López, Francisco del; Moncunill Geniz, Francesc Xavier; Giralt Mas, Ma. Rosa (2020-02-01)
    Article
    Open Access
    Wireless communications play a central role in our modern connected lives; at the same time, they constitute a very broad and deep area of research. The elements that make wireless communications possible are a transmitter, ...

    This paper presents the optimal batch scheduling of a multi-product dairy process using an approach that combines optimization and constraint programming techniques. A suitable model describing the subprocesses and production ...

  • A discrete-time technique for the steady-state analysis of nonlinear class-E amplifiers 

    Águila López, Francisco del; Palà Schönwälder, Pere; Molina Gaudó, Pilar; Mediano Heredia, Arturo (Institute of Electrical and Electronics Engineers (IEEE), 2007-06-11)
    Article
    Open Access
    Switched circuits are widely used, particularly for power electronic applications in which efficiency is important. Of these applications, the class-E amplifier has been given particular attention, since it is theoretically ...

  • Joint symbol and chip synchronization for a burst-mode-communication superregenerative MSK receiver 

    López Riera, Alexis; Águila López, Francisco del; Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Giralt Mas, Ma. Rosa; Moncunill Geniz, Francesc Xavier (2017-01-05)
    Article
    Open Access
    In this paper we describe a superregenerative (SR) MSK receiver able to operate in a burst-mode framework where synchronization is required for each packet. The receiver is based on an SR oscillator which provides samples ...

  • A discrete-time approach to the steady-state and stability analysis of distributed nonlinear autonomous circuits 

    Bonet Dalmau, Jordi; Palà Schönwälder, Pere (2000-02)
    Article
    Open Access
    We present a direct method for the steady-state and stability analysis of autonomous circuits with transmission lines and generic non- linear elements. With the discretization of the equations that describe the circuit ...

  • Stability analysis of periodic solutions in non-linear autonomous circuits: a discrete time approach 

    Miró Sans, Joan Maria; Palà Schönwälder, Pere; Mas Casals, Orestes Miquel (1996-07)
    Article
    Restricted access - publisher's policy
    Steady-state methods have been devised to compute periodic wave-forms without having to integrate the autonomous circuit equations until the transients die out. Stability analysis of the computed solutions is the next ...

  • The Mendeleev-Meyer force project 

    Santos Hernández, Sergio; Lai, Chia-Yun; Amadei, Carlo Alberto; Gadelrab, Karim Raafat; Tang, Tzu-Chieh; Verdaguer Prats, Albert; Barcons Xixons, Víctor; Font Teixidó, Josep; Colchero, Jaimer; Chiesa, Matteo (2016-10-28)
