    • Closed form expressions for maximum delay and jitter in multibeam opportunistic beamforming 

      Zorba, Nizar; Pérez Neira, Ana Isabel (2007)
      Text en actes de congrés
      Accés obert
      Scheduling in a broadcast (BC) channel based on partial channel state information at the transmitter (CSIT) is carried out through a multibeam opportunistic beamforming technique. Within a more practical perspective, this ...

    • Design and performance comparison of a superregenerative MPSK transceiver 

      Bonet Dalmau, Jordi; López Riera, Alexis; Palà Schönwälder, Pere; Moncunill Geniz, Francesc Xavier; Babí Oller, Albert (2015)
      Comunicació de congrés
      Accés obert
      In this paper we present a superregenerative transceiver able to switch among BPSK, QPSK and 8PSK modulations. An HF-band proof-of-concept transceiver is implemented on an FPGA with a minimum of analog circuitry. The ...

    • Development of a network tap architecture for logging multi-gigabit technologies in automotive market 

      Prats Domènech, Guillem (Universitat Politècnica de Catalunya, 2022-09-14)
      Projecte Final de Màster Oficial
      Accés restringit per acord de confidencialitat
      Given the recent strong growth in automotive technology requirements and the increase in bandwidth needed for applications such as ADAS and autonomous driving, it is necessary to create solutions to manage the transport ...

    • Dynamic bit allocation and differential quantization in feedback link for robust power allocation in multiuser opportunistic beamforming 

      Zorba, Nizar; Pascual Iserte, Antonio; Pérez Neira, Ana Isabel (2008)
      Text en actes de congrés
      Accés obert
      Multi-antenna systems provide advantages in terms of link quality and multiuser access capabilities, which can be achieved by using schemes as multibeam opportunistic beamforming. This scheme only requires partial channel ...

    • Resource modeling of mmwave transceivers for wireless communications at the chip scale 

      Kastanioti, Ioanna (Universitat Politècnica de Catalunya, 2022-02-03)
      Projecte Final de Màster Oficial
      Accés restringit per acord de confidencialitat
      Wireless Network-on-Chip (WNoC), where communications takes place at the chip scale between integrated antennas and transceivers and using the chip package as propagation medium, shows promise in addressing the challenges ...

    • The RCap: an architecture for robust beamforming and high resolution DOA tracking 

      Pérez Neira, Ana Isabel; Villarino Villarino, Ramón; Lagunas Hernandez, Miguel A. (2000)
      Text en actes de congrés
      Accés obert
      Motivated by the objective of finding a reduced complexity implementation of the EM (Estimate and Maximize) algorithm, the authors move the concept of altemating projection (AP),re ported in 1988 by I. Ziskind and ...

    • Top-Down Mixed-Signal Verification for a Wireless Transceiver 

      Günther, Sven Kirsten (Universitat Politècnica de Catalunya, 2008)
      Projecte Final de Màster Oficial
      Accés restringit per decisió de l'autor
      In this Master Thesis the verification procedure of the top-down design process was implemented for the receiver sub-system of an IEEE 802.15.4 transceiver. The implemented flexible verification setup in Cadence enables ...
