Compressed matched filter for non-Gaussian noise

, 2013
We consider estimation of a deterministic unknown parameter vector in a linear model with non-Gaussian noise. In the Gaussian case, dimensionality reduction via a linear matched filter provides a simple low dimensional sufficient statistic which can be ...

Variational Bayesian Inference-Based Maximum Correntropy Kalman Filtering for Visual Tracking With Unknown Process and Measurement Noise

IEEE Access
The paper proposes a new Kalman filtering (KF) algorithm called VBI-MCKF that combines the variational Bayesian inference (VBI)-based KF algorithm and the maximum correntropy KF (MCKF) for visual tracking problem.

Dynamical suppression of telegraph and 1/f noise due to quantum bistable fluctuator

, 2004
We study dynamical decoupling of a qubit from non gaussian quantum noise due to discrete sources, as bistable fluctuators and 1/f noise. We obtain analytic and numerical results for generic operating point.

Spatial Matérn Fields Driven by Non‐Gaussian Noise [PDF]

Scandinavian Journal of Statistics, 2013
AbstractThe article studies non‐Gaussian extensions of a recently discovered link between certain Gaussian random fields, expressed as solutions to stochastic partial differential equations (SPDEs), and Gaussian Markov random fields. The focus is on non‐Gaussian random fields with Matérn covariance functions, and in particular, we show how the SPDE ...

Distributions of Conductance and Shot Noise and Associated Phase Transitions

, 2008
For a chaotic cavity with two indentical leads each supporting N channels, we compute analytically, for large N, the full distribution of the conductance and the shot noise power and show that in both cases there is a central Gaussian region flanked on ...

Non-stationary self-similar Gaussian processes as scaling limits of power law shot noise processes and generalizations of fractional Brownian motion [PDF]

, 2019
We study shot noise processes with Poisson arrivals and non-stationary noises. The noises are conditionally independent given the arrival times, but the distribution of each noise does depend on its arrival time. We establish scaling limits for such shot
