PhaseLiftOff: an Accurate and Stable Phase Retrieval Method Based on Difference of Trace and Frobenius Norms

Penghang Yin, Jack Xin

Phase retrieval aims to recover a signal $x\in {\mathbb{C}}^n$ from its amplitude measurements $|<x,a_i>{|}^2$, $i=1,2,...,m$, where $a_i$'s are over-complete basis vectors, with…
