Adaptive detection in nonhomogeneous environments using the generalized eigenrelation [PDF]

open access: yes, 2007
This letter considers adaptive detection of a signal in a nonhomogeneous environment, more precisely under a covariance mismatch between the test vector and the training samples, due to an interference that is not accounted for by the training samples ...

One-Bit Quantization and Distributed Detection with an Unknown Scale Parameter

open access: yesAlgorithms, 2015
We examine a distributed detection problem in a wireless sensor network, where sensor nodes collaborate to detect a Gaussian signal with an unknown change of power, i.e., a scale parameter.

New Findings on GLRT Radar Detection of Non-Fluctuating Targets via Phased Arrays

open access: yesIEEE Access, 2021
This paper addresses the standard generalized likelihood ratio test (GLRT) detection problem of weak signals in background noise. In so doing, we consider a non-fluctuating target embedded in complex white Gaussian noise (CWGN), in which the amplitude of

The multifamily likelihood ratio test for multiple signal model detection

open access: yes, 2005
The generalized likelihood ratio test (GLRT) is a standard tool for designing signal detectors. It produces detectors that perform well when the signal model is known, except for a fixed set of signal parameters.

Robust Spectrum-Based Comparison of Multivariate Complex Random Signals

open access: yesIEEE Access, 2019
We consider the problem of comparing two complex multivariate random signal realizations, possibly contaminated with additive outliers, to ascertain whether they have identical power spectral densities.

Adaptive subspace detection based on two-step dimension reduction in the underwater waveguide

open access: yesDefence Technology, 2021
In the underwater waveguide, the conventional adaptive subspace detector (ASD), derived by using the generalized likelihood ratio test (GLRT) theory, suffers from a significant degradation in detection performance when the samplings of training data are ...

A Comparative Review of Specification Tests for Diffusion Models

open access: yesInternational Statistical Review, Volume 94, Issue 2, Page 347-381, August 2026.
Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.

Polarimetrie Scattering based Support GLRT for Detection of Permanent Scatterers [PDF]

open access: yes, 2021
This paper deals with the characterization of permanent scatterers in polarimetrie synthetic aperture radar (SAR) images of urban environment. Along this line, a scattering property based generalized likelihood ratio (GLRT) test for detection of ...
