SPECTRAL SUBTRACTION AND SPECTRAL ESTIMATION
"... The problem of spectral subtraction, to estimate the parameters of a single source in colored noise, is used to show the relationships between the likelihood formulation and spectral density estimation. Reported previously as a filter bank processing for spectral estimation, it is shown that the nor ..."

QUALITY METRICS FOR SPECTRAL ESTIMATION
, 2010
"... Abstract. The quantitative assessment of the spectral estimation quality in multispectral imaging systems is an active field of research. The design and optimization of multispectral imaging systems are very dependent on how the cost function is selected. Several spectral estimation metrics have bee ..."

Spin Needlets Spectral Estimation
, 2009
"... We consider the statistical analysis of random sections of a spin fibre bundle over the sphere. These may be thought of as random fields that at each point p ∈ S 2 take as a value a curve (e.g. an ellipse) living in the tangent plane at that point TpS 2, rather than a number as in ordinary situation ..."

situations. The analysis of such fields is strongly motivated by applications, for instance polarization experiments in Cosmology. To investigate such fields, spin needlets were recently introduced by [21] and [20]. We consider the use of spin needlets for spin angular power spectrum estimation
Multirate Spectral Estimation

, 2001
"... This article introduces a mathematical theory for estimating the power spectral density (PSD) of a random signal based on lowsamplingrate measurements. We formulate the problem using a mathematical model where an observer sees a discretetime WSS random signal x(n) through a bank of measurement de ..."

Generalized Spectral Estimation
, 1996
"... This paper provides a framework for estimating parameters in a wide class of dynamic rational expectations models. The framework recognizes that dynamic RE models are often meant to match the data only in limited ways. In particular, interest may focus on a subset of frequencies. Thus, this paper de ..."

SPECTRAL ESTIMATES ON THE SPHERE
, 2013
"... Abstract. In this article we establish optimal estimates for the first eigenvalue of Schrödinger operators on the ddimensional unit sphere. These estimates depend on Lp norms of the potential, or of its inverse, and are equivalent to interpolation inequalities on the sphere. We also characterize a ..."

Spectral estimates on 2tori
, 2000
"... We prove upper and lower bounds for the eigenvalues of the Dirac operator and the Laplace operator on 2dimensional tori. In particluar we give a lower bound for the first eigenvalue of the Dirac operator for nontrivial spin structures. It is the only explicit estimate for eigenvalues of the Dirac ..."

SPECTRAL ESTIMATES FOR DIFFERENTIAL FORMS
, 2005
"... In this expository paper we review two recent estimates on the first eigenvalue of the Laplacian acting on differential forms. We start by recalling the classical facts on harmonic forms on closed manifolds; then we introduce the absolute and relative boundary conditions and report on recent sharp e ..."
