  • Asymptotically optimal linear shrinkage of sample LMMSE and MVDR filters 

    Serra, Jordi; Nájar Martón, Montserrat (2014-07-15)
    Article
    Restricted access - publisher's policy
    Conventional implementations of the linearminimum mean-square (LMMSE) and minimum variance distortionless response (MVDR) estimators rely on the sample matrix inversion (SMI) technique, i.e., on the sample covariance matrix ...
  • Cramer-rao bound for time-delay estimation in the frequency domain 

    Serra, Jordi; Blanco, Luis; Nájar Martón, Montserrat (European Association for Signal Processing (EURASIP), 2009)
    Conference report
    Restricted access - publisher's policy
    In this paper a measure of performance of time delay estimators arising from a frequency model of the received signal is presented. The aim is to derive theoretical analysis of the Cramer-Rao bound (CRB) for time delay ...
  • Double shrinkage correction in sample LMMSE estimation 

    Serra, Jordi; Nájar Martón, Montserrat (European Association for Signal Processing (EURASIP), 2013)
    Conference report
    Restricted access - publisher's policy
    The sample linear minimum mean square error (LMMSE) es- timator undergoes high performance degradation in the small sample size regime. Herein a double shrinkage correction is proposed to alleviate this problem. First, ...
  • Optimal linear correction in LMMSE estimation using moments of the complex inverse Wishart distribution 

    Serra, Jordi; Nájar Martón, Montserrat (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Conference report
    Restricted access - publisher's policy
    The conventional linear minimum mean square error esti- mator (LMMSE) suffers a severe performance degradation whenever the sample size is comparable to the observation dimension. In order to tackle this problem, we ...
  • The CTTC 5G end-to-end experimental platform: integrating heterogeneous wireless/optical networks, distributed cloud, and IoT devices 

    Muñoz González, Raul; Mangues Bafalluy, Josep; Vilalta, Ricard; Verikoukis, Christos; Alonso Zárate, Jesús; Georgiadis, Apostolos; Payaró Llisterri, Miquel; Pérez Neira, Ana Isabel; Casellas Regi, Ramón; Martínez Rivera, Ricardo Victor; Núñez Martínez, José; Requena Esteso, Manuel; Pubill, David; Font Bach, Oriol; Henarejos Hernández, Pol; Serra, Jordi; Vázquez Gallego, Francisco (2016-01-29)
