The main goal of this project is to apply linear algebra techniques to signal processing, circuits and systems, taking into account noise and parametric uncertainties. The similarity of the techniques handling signals and systems strongly links these areas, usually addressed separately. The use of the same transforms (Laplace, Fourier and Z) and methods (matrix inequalities, symbolic computation, optimization algorithms) is a clear indication that signals and systems can be treated through a common theory, producing similar solution to related problems. The topics to be covered are: stability and control design of dynamical systems, uniform orthogonalization of signals, estimation of direction of arrival using array of sensors, objective assessment of speech and audio quality. The expected results are: to disseminate the research results through conferences and technical journals, to develop human resources and to produce a textbook (for both graduate and undergraduate electrical engineering students) about signals and systems. Development of human resources: The themes treated in the project are centered on control and telecommunications, which have a high potential to attract new researchers, including undergraduate students. The main researchers have experience in the topics of the project and have been involved in developing human resources along the last ten years (PhD and MSc degrees). Methodology: The methods and techniques to be used in the project are up-to-date, as can be verified through recent publications in technical journals and conferences. The use of computational models and simulations has been an effective methodology to solve control and telecommunication problems in electrical engineering, thus assuring the viability of the project. Resources: The resources requested are concentrated on computational infrastructure, with associate demands for attending conferences and scholarships (post-doctoral, doctoral, master and scientific initiation programs). The amount of resources demanded has been defined in accordance with the size of the research team of the project [...] (AU)
