Robust and Sparse M-Estimation of DOA
Christoph F. Mecklenbräuker, Peter Gerstoft, Esa Ollila +1
A robust and sparse Direction of Arrival (DOA) estimator is derived for array data that follows a Complex Elliptically Symmetric (CES) distribution with zero-mean and finite second…
Multi Snapshot Sparse Bayesian Learning for DOA Estimation
Peter Gerstoft, Christoph F. Mecklenbräuker, Angeliki Xenaki
The directions of arrival (DOA) of plane waves are estimated from multi-snapshot sensor array data using Sparse Bayesian Learning (SBL). The prior source amplitudes is assumed inde…
Multiple and single snapshot compressive beamforming
Peter Gerstoft, Angeliki Xenaki, Christoph F. Mecklenbräuker
For a sound field observed on a sensor array, compressive sensing (CS) reconstructs the direction-of-arrival (DOA) of multiple sources using a sparsity constraint. The DOA estimati…
Using the LASSO's Dual for Regularization in Sparse Signal Reconstruction from Array Data
Christoph F. Mecklenbräuker, Peter Gerstoft, Erich Zöchmann
Waves from a sparse set of source hidden in additive noise are observed by a sensor array. We treat the estimation of the sparse set of sources as a generalized complex-valued LASS…
