Wave packet systems and connections to spectral analysis of limiting operators
Published 11 Jan 2026 in math.CA, math-ph, math.FA, and math.SP | (2601.06945v1)
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.
