Inverting Spectrogram Measurements via Aliased Wigner Distribution Deconvolution and Angular Synchronization
Michael Perlmutter, Sami Merhi, Aditya Viswanathan +1
We propose a two-step approach for reconstructing a signal from subsampled short-time Fourier transform magnitude (spectogram) measurements: First, we use…

Large Deviations from the Hydrodynamic Limit for a System with Nearest Neighbor Interactions
Sayan Banerjee, Amarjit Budhiraja, Michael Perlmutter
We give a new proof of the large deviation principle from the hydrodynamic limit for the Ginzberg-Landau model studied in Donsker and Varadhan (1989) using techniques from the theo…
