Phase Retrieval for $L^2([-\pi ,\pi ])$ via the Provably Accurate and Noise Robust Numerical Inversion of Spectrogram Measurements

Mark Iwen, Michael Perlmutter, Nada Sissouno +1

In this paper, we focus on the approximation of smooth functions $f:[-\pi ,\pi ]\to \mathbb{C}$, up to an unresolvable global phase ambiguity, from a finite set of Short Time…
