      The waveforms being employed by fourthgeneration (4G) and candidate fifth-generation (5G) radio access and wireless backhaul technologies are based on modulation techniques that allow significantly increased spectral ...

    • Slow-envelope shaping function FPGA implementation for 5G NR envelope tracking PA 

      Li, Wantao; Bartzoudis, Nikolaos; Rubio Fernández, José; López Bueno, David; Montoro López, Gabriel; Gilabert Pinal, Pere Lluís (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      This paper focuses on the FPGA implementation of a slew-rate reduction (SR) shaping function for envelope tracking (ET) power amplifiers (PAs). The SR envelope has been proved effective to trade-off power efficiency and ...
