Injectivity conditions for STFT phase retrieval on $\mathbb{Z}$, ${\mathbb{Z}}_d$ and ${\mathbb{R}}^d$

David Bartusel

We study the phase retrieval problem for the short-time Fourier transform on the groups $\mathbb{Z}$, ${\mathbb{Z}}_d$ and ${\mathbb{R}}^d$. As is well-known, phase retrieval is possib…
