Phaseless super-resolution is the problem of recovering an unknown signal from measurements of the “magnitudes” of the “low frequency” Fourier transform of the signal. This problem arises in applications where measuring the phase, and making high-frequency measurements, are either too costly or alto…
Phaseless super-resolution is the problem of reconstructing a signal from its low-frequency Fourier magnitude measurements. It is the combination of two classic signal processing problems: phase retrieval and super-resolution. Due to the absence of phase and high-frequency measurements, additional i…
The problem of recovering signals from the Short-Time Fourier Transform (STFT) magnitude is of paramount importance in many areas of engineering and physics. This problem has received a lot of attention over the last few decades, but not much is known about conditions under which the STFT magnitude…
