Many signals are modeled as a superposition of exponential functions in spectroscopy of
chemistry, biology, and medical imaging. This paper studies the problem of recovering …

The method of super-resolution phase retrieval (PR) for Fourier phaseless measurement
extends the signal model of PR from the discrete domain to a more realistic continuous …

Neuromorphic sampling is a bioinspired and opportunistic analog-to-digital conversion
technique, where the measurements are recorded only when there is a significant change in …

A fundamental challenge in non-destructive evaluation using ultrasound is to accurately
estimate the thicknesses of different layers or cracks present in the object under …

Abstract The existing Finite Rate of Innovation (FRI) sampling theory can realize the efficient
measurement of Gaussian pulse streams with fixed modal functions. However, it is hard to …

The finite-rate-of-innovation (FRI) sampling frame has drawn a great deal of attention in
many applications. In this paper, a novel sub-Nyquist FRI-based sampling and …

Aiming for the robustness improvement in a noisy environment, we propose a new
representation method based on Lorentzian pulse fitting for the analytical expression …

Abstract Finite Rate of Innovation (FRI) sampling theory offers an efficient approach for the
sub-Nyquist measurement of the short pulse stream signal, but it can only address …

Accurate measurement of multi-dimensional pulse streams signal is of great significance in
the field of instrumentation and measurement, radar, communication and signal processing …

Mismatches between samples and their respective channel or target commonly arise in
several real-world applications. For instance, whole-brain calcium imaging of freely moving …
