This presentation treats three aspects of high resolution spectral estimation - firstly the side-lobe structure of MEM spectra is studied, next a link between MEM and ML spectrum estimates is derived, which allows a clear explanation for the smoothing in ML spectra, and finally an approach is proposed for designing an iterative scheme to estimate the spectrum of an ARMA process.
