Signal Processing and Control

Collaborators in aeronautical engineering were interested in the numerical solution of a constrained Sylvester equation, with applications in control theory, and we developed an efficient algorithm [C05] [C06] [C08] [J34] [J35].

An efficient variant of the ESPRIT algorithm for determining direction of arrival of signals reaching an array of sensors was developed [C10] [J40].
