    • 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, ...
    • Experiencias de concesión del mantenimiento y la construcción de las carreteras de las Diputaciones provinciales en España

      Article
      Open Access
      En el presente artículo se revisan las recientes concesiones de la explotación de redes viales de bajo volumen de tráfico por parte de Diputaciones provinciales españolas. Se introducen, primeramente, los riesgos e ...
    • 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 ...
