Uncertainty principles for the short‐time Fourier transform on the lattice
Mathematische Nachrichten, 2023 AbstractIn this paper, we study a few versions of the uncertainty principle for the short‐time Fourier transform on the lattice . In particular, we establish the uncertainty principle for orthonormal sequences, Donoho–Stark's uncertainty principle, Benedicks‐type uncertainty principle, Heisenberg‐type uncertainty principle, and local uncertainty ...

Blind Phaseless Short-Time Fourier Transform Recovery [PDF]
IEEE Transactions on Information Theory, 2020 The problem of recovering a pair of signals from their blind phaseless short-time Fourier transform measurements arises in several important phase retrieval applications, including ptychography and ultra-short pulse characterization. In this paper, we prove that in order to determine a pair of generic signals uniquely, up to trivial ambiguities, the ...

Interference Suppression Algorithm Based on Short Time Fractional Fourier Transform
SensorsNarrowband interference and wideband interference are both common jamming signals against synthetic aperture radar, which can degrade the signal severely.

Communications Materials, 2023 Overlapping short- and long-lived luminescence signals are often encountered and are not trivial to disentangle in a single measurement. Here, we demonstrate for a broad range of emitters that time gated Fourier transform spectroscopy can be used as a ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Rotor-System Log-Decrement Identification Using Short-Time Fourier-Transform Filter
International Journal of Rotating Machinery, 2015 With the increase of the centrifugal compressor capability, such as large scale LNG and CO2 reinjection, the stability margin evaluation is crucial to assure the compressor work in the designed operating conditions in field.
