Sparse Sampling in Fractional Fourier Domain: Recovery Guarantees and Cramér-Rao Bounds
Václav Pavlíček, Ayush Bhandari
Sampling theory in fractional Fourier Transform (FrFT) domain has been studied extensively in the last decades. This interest stems from the ability of the FrFT to generalize the t…
Time Encoding via Unlimited Sampling: Theory, Algorithms and Hardware Validation
Dorian Florescu, Ayush Bhandari
An alternative to conventional uniform sampling is that of time encoding, which converts continuous-time signals into streams of trigger times. This gives rise to Event-Driven Samp…
Back in the US-SR: Unlimited Sampling and Sparse Super-Resolution with its Hardware Validation
Ayush Bhandari
The Unlimited Sensing Framework (USF) is a digital acquisition protocol that allows for sampling and reconstruction of high dynamic range signals. By acquiring modulo samples, the…
Super-Resolution in Phase Space
Ayush Bhandari, Yonina Eldar, Ramesh Raskar
This work considers the problem of super-resolution. The goal is to resolve a Dirac distribution from knowledge of its discrete, low-pass, Fourier measurements. Classically, such p…
