Asynchronous Multi-Channel USF: Modified CRT for Modulo Unfolding
Ruiming Guo, Ayush Bhandari
The Unlimited Sampling Framework (USF) overcomes the traditional trade-off between dynamic range and digital resolution, achieving performance unattainable with standard ADCs. Its…
Unlocking Off-the-Grid Sparse Recovery with Unlimited Sensing: Simultaneous Super-Resolution in Time and Amplitude
Ruiming Guo, Ayush Bhandari
The recovery of Dirac impulses, or spikes, from filtered measurements is a classical problem in signal processing. As the spikes lie in the continuous domain while measurements are…
USF Spectral Estimation: Prevalence of Gaussian Cramér-Rao Bounds Despite Modulo Folding
Ruiming Guo, Ayush Bhandari
Spectral Estimation (SpecEst) is a core area of signal processing with a history spanning two centuries and applications across various fields. With the advent of digital acquisiti…
Blind Time-of-Flight Imaging: Sparse Deconvolution on the Continuum with Unknown Kernels
Ruiming Guo, Ayush Bhandari
In recent years, computational Time-of-Flight (ToF) imaging has emerged as an exciting and a novel imaging modality that offers new and powerful interpretations of natural scenes,…
