This webinar is the next in a series by the IEEE Synthetic Aperture Technical Working Group (SA-TWG)
Abstract
This seminar presents reduced-rank techniques for array signal processing some applications and discusses future perspectives. The underlying theory of reduced-rank signal processing is introduced using a simple linear algebra approach. The main reduced-rank methods proposed to date are reviewed and are compared in terms of their advantages and disadvantages. A general framework for reduced-rank processing based on the minimum mean squared error (MMSE) and minimum variance (MV) design criteria is presented and used for motivating the design of the transformation that performs dimensionality reduction. Following this general framework, we discuss several existing reduced-rank methods and illustrate their performance for array signal processing applications such as beamforming, direction finding and radar systems.
Biography
Rodrigo C. de Lamare was born in Rio de Janeiro, Brazil, in 1975. He received his Diploma in electronic engineering from the Federal University of Rio de Janeiro in 1998 and the MSc and PhD degrees in electrical engineering from the Pontifical Catholic University of Rio de Janeiro (PUC-Rio) in 2001 and 2004, respectively. Since January 2006, he has been with the Communications Group, School of Physics, Engineering and Technology, University of York, United Kingdom, where he is a Professor. Since April 2013, he has also been a Professor at PUC-RIO. Dr de Lamare is a senior member of the IEEE and an elected member of the IEEE Signal Processing for Communications and Networking Committee and the IEEE Sensor Array and Multichannel Signal Processing. He served as editor for IEEE Wireless Communications Letters and IEEE Transactions on Communications, and is currently an associate editor of IEEE Transactions on Signal Processing. His research interests lie in communications and signal processing, areas in which he has published over 500 papers in international journals and conferences.
