Phase retrieval from sampled Gabor transform magnitudes: Counterexamples
Rima Alaifari, Matthias Wellershoff
We consider the recovery of square-integrable signals from discrete, equidistant samples of their Gabor transform magnitude and show that, in general, signals can not be recovered…
Phase retrieval of bandlimited functions for the wavelet transform
Rima Alaifari, Francesca Bartolucci, Matthias Wellershoff
We study the recovery of square-integrable signals from the absolute values of their wavelet transforms, also called wavelet phase retrieval. We present a new uniqueness result for…
Uniqueness of STFT phase retrieval for bandlimited functions
Rima Alaifari, Matthias Wellershoff
We consider the problem of phase retrieval from magnitudes of short-time Fourier transform (STFT) measurements. It is well-known that signals are uniquely determined (up to global…
