On the effect of zero-flipping on the stability of the phase retrieval problem in the Paley-Wiener class

Philippe Jaming, Karim Kellay, Rolando Perez

In the classical phase retrieval problem in the Paley-Wiener class $P W_{L}$ for $L > 0$ , i.e. to recover $f \in P W_{L}$ from $∣ f ∣$ , Akutowicz, Walther, and Hofstetter independently showed…

Phase retrieval for wide-band signals

Philippe Jaming, Karim Kellay, Rolando Perez

This study investigates the phase retrieval problem for wide-band signals. We solve the following problem: given f $\in$ L 2 (R) with Fourier transform in L 2 (R, e^{2c|x|} dx), we…
