  • Capacity of MIMO Channels: asymptotic evaluation under correlated fading 

    Mestre Pons, Francesc X.; Rodríguez Fonollosa, Javier; Pagès Zamora, Alba Maria (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2003-06-30)
    Article
    Open Access
    This paper investigates the asymptotic uniform power allocation capacity of frequency nonselective multiple-input multiple-output channels with fading correlation at either the transmitter or the receiver. We consider ...
  • Characterization of the distortion of OFDM/OQAM modulations under frequency selective channels 

    Mestre Pons, Francesc X.; Sánchez Fernández, Matilde; Pascual Iserte, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Conference lecture

    Filterbank based multicarrier modulations are well known to perform poorly in frequency selective channels when single tap carrier-by-carrier equalization is used. This degradation is cased by the inherent distortion ...
  • ML approaches to channel estimation for pilot-aided multi-rate DS/CDMA systems 

    Mestre Pons, Francesc X.; Rodríguez Fonollosa, Javier (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2002-03-31)
    Article
    Open Access
    This paper analyzes the asymptotic performance of maximum likelihood (ML) channel estimation algorithms in wideband code division multiple access (WCDMA) scenarios. We concentrate on systems with periodic spreading sequences ...
  • Single input multiple output techniques for Hiperlan/ 2 

    Pérez Neira, Ana Isabel; Bartolomé Calvo, Diego; Mestre Pons, Francesc X. (2001)
    Conference report
    Open Access
    In this paper, the use of adaptive antennas for Orthogonal Frequency Division Multiplexing (OFDM) is studied. More in concrete the paper is devoted to possible standard-jiendly techniques for Hiperlan/2 (HL/2). First, the ...
  • Smart antennas in software radio base stations 

    Pérez Neira, Ana Isabel; Mestre Pons, Francesc X.; Rodríguez Fonollosa, Javier (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2001-02-28)
    Article
    Open Access
    The application of adaptive antenna techniques to fixed-architecture base stations has been shown to offer wide-ranging benefits, including interference rejection capabilities or increased coverage and spectral ...
  • Spatial filtering for pilot-aided WCDMA systems: a semi-blind subspace approach 

    Mestre Pons, Francesc X.; Rodríguez Fonollosa, Javier (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2003-10-31)
    Article
    Open Access
    This paper proposes a spatial filtering technique for the reception of pilot-aided multirate multicode direct-sequence code division multiple access (DS/CDMA) systems such as wideband CDMA (WCDMA). These systems introduce ...
  • The IST METRA Project 

    Rodríguez Fonollosa, Javier; Heikkilä, Markku; Kermoal, Jean Philippe; Mestre Pons, Francesc X.; Pagès Zamora, Alba Maria; Pollard, Adam; Schumacher, Laurent; Ylitalo, Juha; Gaspa Maynou, Roger (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2002-07-31)
    Article
    Open Access
    This article summarizes the main achievements of the Multi-Element Transmit and Receive Antennas (METRA) Project, an IST research and technological development project carried out between January 2000 and June 2001 by ...
