Off-Grid Direction-of-Arrival Estimation Using Second-Order Taylor Approximation
Huiping Huang, Hing Cheung So, Abdelhak M. Zoubir
The problem of off-grid direction-of-arrival (DOA) estimation is investigated. We develop a grid-based method to jointly estimate the closest spatial frequency (the sine of DOA) gr…
Minimax Robust Landmine Detection Using Forward-Looking Ground-Penetrating Radar
Afief Dias Pambudi, Michael Fauß, Fauzia Ahmad +1
We propose a robust likelihood-ratio test (LRT) to detect landmines and unexploded ordnance using a forward-looking ground-penetrating radar. Instead of modeling the distributions…
Multiple Hypothesis Testing Framework for Spatial Signals
Martin Gölz, Abdelhak M. Zoubir, Visa Koivunen
The problem of identifying regions of spatially interesting, different or adversarial behavior is inherent to many practical applications involving distributed multisensor systems.…
Robust Regularized Locality Preserving Indexing for Fiedler Vector Estimation
Aylin Tastan, Michael Muma, Abdelhak M. Zoubir
The Fiedler vector of a connected graph is the eigenvector associated with the algebraic connectivity of the graph Laplacian and it provides substantial information to learn the la…
Minimax Robust Detection: Classic Results and Recent Advances
Michael Fauß, Abdelhak M. Zoubir, H. Vincent Poor
This paper provides an overview of results and concepts in minimax robust hypothesis testing for two and multiple hypotheses. It starts with an introduction to the subject, highlig…
Asymptotically Optimal Procedures for Sequential Joint Detection and Estimation
Dominik Reinhard, Michael Fauß, Abdelhak M. Zoubir
We investigate the problem of jointly testing multiple hypotheses and estimating a random parameter of the underlying distribution in a sequential setup. The aim is to jointly infe…
