    • ARMA model maximum entropy power spectral estimation 

      Lagunas Hernandez, Miguel A.; Santamaría Pérez, María Eugenia; Figueiras Vidal, Aníbal R. (1984-10)
      Article
      Open Access
    • Cross spectrum ML estimate 

      Lagunas Hernandez, Miguel A.; Santamaría Pérez, María Eugenia; Gasull Llampallas, Antoni; Moreno Bilbao, M. Asunción (Institute of Electrical and Electronics Engineers (IEEE), 1985)
      Conference report
      Open Access
      This work reports how to include general concepts of the one-dimensional MLM procedure in a two-channel problem of cross-spectrum estimation. It is shown in the sequel that there is no any problem in extrapolating the ...
    • Extracción en lazo abierto de la fase de portadora en sistemas de demodulación coherente 

      Cabrera-Bean, Margarita; Santamaría Pérez, María Eugenia; Lagunas Hernandez, Miguel A. (1989)
      Conference report
      Open Access
      The Burst transmision of digital data, using Time Division Multiple Access, has became one of the more usual techniques in the satellite communications systems. In this paper, a method for carrier phase extraction in a ...
    • Multibeam adaptive array 

      Cabrera-Bean, Margarita; Lagunas Hernandez, Miguel A.; Santamaría Pérez, María Eugenia (1988)
      Conference report
      Open Access
      To achieve adaptive multibeamforming to allow reconfiguration in SSW-TDMA satellite communications, a system for narrow band adaptive multibeamforming is described in this work. The signal processor allows an unconstrained ...
    • Neural nets filters: integrated coding and signaling in communication systems 

      Santamaría Pérez, María Eugenia; Lagunas Hernandez, Miguel A.; Cabrera-Bean, Margarita (1989)
      Conference report
      Open Access
      The authors describe the potential of neural net filters in communication systems. They consider applications of neural networks in those fields associated with communications where time-varying linear systems need to be ...
    • Predicción lineal de norma mínima en la detección de fuentes en ruido 

      Lagunas Hernandez, Miguel A.; Santamaría Pérez, María Eugenia (Unión Científica Internacional de Radio (URSI), 1983)
      Conference report
      Open Access
      This work deals with the problem of detecting deterministic sinusoids in white noise. The procedure, due to kumaresan and Tufts (T-K), is briefly described as a minimum norm exact-linear-prediction design. This method has ...
