Compressed matched filter for non-Gaussian noise [PDF]

open access: yes2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014
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 easily communicated and/or stored for future inference.

Underwater surveillance in non-Gaussian noisy environment

open access: yesMeasurement + Control, 2020
The aim of this paper is to evaluate the performance of different filtering algorithms in the presence of non-Gaussian noise environment for tracking underwater targets, using Doppler frequency and bearing measurements.

Phase tracking for sub-shot-noise-limited receivers

open access: yesPhysical Review Research, 2020
Nonconventional receivers for phase-coherent states based on non-Gaussian measurements such as photon counting surpass the sensitivity limits of shot-noise-limited coherent receivers, the quantum noise limit (QNL). These non-Gaussian receivers can have a

Detection in Non-Gaussian Noises [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1970
Stimulus-oriented theories of signal detection are based upon an analysis of the detailed statistical character of the stimulus. When the background for detection is band-limited white Gaussian noise, predictions of human performance by these models are generally good. Since the synchronous random telegraph wave and tones, frequency modulated by noise,

Patch similarity under non Gaussian noise [PDF]

open access: yes2011 18th IEEE International Conference on Image Processing, 2011
Many tasks in computer vision require to match image parts. While higher-level methods consider image features such as edges or robust descriptors, low-level approaches compare groups of pixels (patches) and provide dense matching. Patch similarity is a key ingredient to many techniques for image registration, stereo-vision, change detection or ...

An Improved Gaussian Sum Extended Kalman Filter With Colored Noise for GNSS/SINS Tightly Coupled Positioning and Attitude Determination Systems

open access: yesIEEE Access
The Gaussian sum extended Kalman filter (GSEKF), as a nonlinear non-Gaussian filter, disregards the impact of colored noise components in non-Gaussian noise engendered by external interference, which may compromise the estimation accuracy in global ...

Improved Robust High-Degree Cubature Kalman Filter Based on Novel Cubature Formula and Maximum Correntropy Criterion with Application to Surface Target Tracking

open access: yesJournal of Marine Science and Engineering, 2022
Robust nonlinear filtering is an important method for tracking maneuvering targets in non-Gaussian noise environments. Although there are many robust filters for nonlinear systems, few of them have ideal performance for mixed Gaussian noise and non ...

Stochastic Resonance in a special type of Asymmetric Nonlinear System Driven by Correlated Noise

open access: yes四川大学学报. 自然科学版, 2020
We have analyzed the phenomenon of stochastic resonance in an asymmetric bistable system driven by multiplicative non-Gaussian noise and additive Gaussian noise.

Non-Gaussian noise induced stochastic resonance in FitzHugh–Nagumo neural system with time delay

open access: yesAIP Advances, 2020
In this paper, non-Gaussian noise induced stochastic resonance for the FitzHugh–Nagumo neural system with a time delay is investigated. Through the path integral method, the non-Gaussian noise is approximated as a colored noise, and according to the ...

On the Role of Non-Gaussian Noises on Noise-Induced Phenomena [PDF]

open access: yes, 2004
Most of the studies of noise-induced phenomena assume that the noise source is Gaussian (either white or colored). Here we present recent results of some of those noise-induced phenomena when driven by a noise source taken as colored and non-Gaussian, generated by a nonextensive g-distribution.
