      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, ...

    • A superregenerative QPSK receiver 

      Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2014-01)
      Article
      Accés obert
      In this paper we present a description and experimental verification of a superregenerative receiver (SR) for QPSK signals. Exploiting the fact that a conventional SR generates pulses which preserve the input phase ...

    • Superregenerative reception of narrowband FSK modulations 

      Palà Schönwälder, Pere; Bonet Dalmau, Jordi; López Riera, Alexis; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (2015-03-01)
      Article
      Accés obert
      In this paper we investigate the possibilities of narrowband FSK detection using a superregenerative (SR) receiver. Previous SR FM demodulation techniques rely on detecting the amplitude variations caused by the different ...

    • The nonlinear class-E amplifier: a case study of harmonic balance applied to switched circuits 

      Bonet Dalmau, Jordi; Águila López, Francisco del; Moncunill Geniz, Francesc Xavier; Palà Schönwälder, Pere (IEEE Press. Institute of Electrical and Electronics Engineers, 2009-05)
      Text en actes de congrés
      Accés obert
      Nonlinear switched circuits are usually analyzed in the time domain. The use of frequency-domain methods to analyze the steady-state of switched circuits is usually restricted to linear circuits and, although Volterra ...

    • Ultra wideband impulse radio superregenerative reception 

      Moncunill Geniz, Francesc Xavier; Palà Schönwälder, Pere; Bonet Dalmau, Jordi; Águila López, Francisco del; Giralt Mas, Ma. Rosa (Intech, 2011-07-31)
