We study the problem of phase retrieval in which one aims to recover a function $f$ from the magnitude of its wavelet transform $|\mathcal{W}_\psi f|$. We consider bandlimited functions and derive new uniqueness results for phase retrieval, where the wavelet itself can be complex-valued. In particular, we prove the first uniqueness result for the case that the wavelet $\psi$ has a finite number of vanishing moments. In addition, we establish the first result on unique reconstruction from…

Reconstruction of Bandlimited Functions from Unsigned Samples
It is shown that the recovery of real-valued bandlimited functions from the absolute values of their samples, possibly spaced nonuniformly, is always possible if the function is sampled at more than twice its Nyquist rate, and it is proved that it converges exponentially rapidly in the number of samples used.
