Cepstrum constraints in ME spectral estimation Lagunas Hernandez, Miguel A. Àrees temàtiques de la UPC::Enginyeria de la telecomunicació Equations Spectrum analysis Autocorrelation Cepstrum Constraint optimization Equations Equacions Anàlisi espectral Current trends in spectral estimation techniques follow basicaly two guidelines; by introducing modifications in the objctive function to be minimized or, keeping the objetive, by modifying the set of constraints in the minimization procedure. This work can be encompassed in the second sense, showing the potential of cepstrum constraints in spectral estimation methods. The special features associated with this constraints allow to use raw approximations in order to linearize or simplify the computations involved in the procedure maintaning within margins of adequate quality the resulting estimate.
