Title: Wave packet systems and connections to spectral analysis of limiting operators
Abstract: We discuss the design of “wave packet systems” that admit strong concentration properties in phase space. We make a connection between this problem and topics in signal processing related to the spectral behavior of spatial and frequency-limiting operators. The results have engineering applications in medical imaging, geophysics, and astronomy.
