      Benner, Peter; Novaković, Vedran; Plaza, Antonio; Quintana-Orti, Enrique S. Institute of Electrical and Electronics Engineers (IEEE) (2015-02)
      In this letter, we introduce an efficient algorithm to estimate the noise correlation matrix in the initial stage of the hyperspectral signal identification by minimum error (HySime) method, commonly used for signal subspace ...
