Parameter estimation: known vector signals in unknown Gaussian noise
Abstract This paper develops recursive, convergent estimators for the parameters of finite Gaussian mixtures with a common covariance matrix. The mean vectors (signals) of the component densities are assumed to be known. The motivation for the study stems from digital communication. The basic approach is first illustrated for the case of an independent identically distributed sequence of sample...
متن کاملAsymptotic Equivalence of Density Estimation and Gaussian White Noise
Signal recovery in Gaussian white noise with variance tending to zero has served for some time as a representative model for nonparametric curve estimation, having all the essential traits in a pure form. The equivalence has mostly been stated informally, but an approximation in the sense of Le Cam’s deficiency distance 1 would make it precise. The models are then asymptotically equivalent for ...
متن کاملConstructive Asymptotic Equivalence of Density Estimation and Gaussian White Noise
A recipe is provided for producing, from a sequence of procedures in the Gaus-sian regression model, an asymptotically equivalent sequence in the density estimation model with i. i. d. observations. The recipe is, to put it roughly, to calculate normalised frequencies over certain intervals, add a small random distortion, calculate square roots, and pretend these to be observations from a Gauss...
متن کاملAsymptotic Equivalence of Spectral Density Estimation and Gaussian White Noise
We consider the statistical experiment given by a sample y(1), . . . , y(n) of a stationary Gaussian process with an unknown smooth spectral density f . Asymptotic equivalence, in the sense of Le Cam’s deficiency ∆-distance, to two Gaussian experiments with simpler structure is established. The first one is given by independent zero mean Gaussians with variance approximately f(ωi) where ωi is a...
متن کاملGeneralized free Gaussian white noise
Based on an adequate new Gel’fand triple, we construct the infinite dimensional free Gaussian white noise measure μ using the Bochner-Minlos theorem. Next, we give the chaos decomposition of an L2 space with respect to the measure μ .
