Displacement structure: theory and applications
Thomas Kailath,Ali H. Sayed +1 more
TL;DR: This survey paper describes how strands of work that are important in two different fields, matrix theory and complex function theory, have come together in some work on fast computational algorithms for matrices with what the authors call displacement structure, and develops a fast triangularization procedure.

Subspace-based signal analysis using singular value decomposition
TL;DR: A unified approach is presented to the related problems of recovering signal parameters from noisy observations and identifying linear system model parameters from observed input/output signals, both using singular value decomposition (SVD) techniques.
