[HTML][HTML] Polynomial eigenvalue decomposition for eigenvalues with unmajorised ground truth–Reconstructing analytic dinosaurs

SJ Schlecht, S Weiss - Science Talks, 2025 - Elsevier
When estimated space-time covariance matrices from finite data, any intersections of ground
truth eigenvalues will be obscured, and the exact eigenvalues become spectrally majorised …

Polynomial Matrix SVD via Generalized Sequential Matrix Diagonalisation

FA Khattak, S Redif, M Bakhit - Authorea Preprints, 2024 - techrxiv.org
The singular value decomposition (SVD) of polynomial matrices plays a pivotal role in the
analysis and optimisation of broadband multi-input multi-output (MIMO) systems. In this …
