Talk Title: Compressive Sensing RF Signals with Photonic Systems
Abstract: We and other researchers worldwide have now developed several photonics approaches for measuring the properties of sparse RF signals using compressive sensing. In this talk I will review the most promising of these approaches, compare them and talk about several special issues that arise in photonic compressive sensing. These issues include mixing matrix calibration, recovery of off-the-grid sinusoids, and reducing system complexity.
Biography: George C. Valley has an AB from Dartmouth College and a PhD from The University of Chicago, both in physics. He has worked at Cornell Aeronautical Laboratories, Hughes Aircraft Company, and is now Senior Scientist at The Aerospace Corporation. Past research work has focused on nonlinear optics, optical solitons, photorefractive materials, free-space laser communication and wave propagation in random media. Current research interests include photonic analog-to-digital converters, optical signal processing and compressive sensing.
