2000 (English)In: IEEE Transactions on Signal Processing, ISSN 1053-587X, E-ISSN 1941-0476, Vol. 48, no 11, 3189-3205 p.Article in journal (Refereed) Published
Traditional maximum entropy spectral estimation determines a power spectrum from covariance estimates. Here, we present a new approach to spectral estimation, which is based on the use of filter banks as a means of obtaining spectral interpolation data, Such data replaces standard covariance estimates, A computational procedure for obtaining suitable pole-zero (ARMA) models from such data is presented. The choice of the zeros (MA-part) of the model is completely arbitrary. By suitably choices of filterbank poles and spectral zeros, the estimator can be tuned to exhibit high resolution in targeted regions of the spectrum.
