Spectral Method for Phase Retrieval: an Expectation Propagation Perspective

Junjie Ma, Rishabh Dudeja, Ji Xu +2

Phase retrieval refers to the problem of recovering a signal ${\mathbf{x}}_{\star }\in {\mathbb{C}}^n$ from its phaseless measurements $y_i=|{\mathbf{a}}_i^{\mathrm{H}}{\mathbf{x}}_{\star }|$…
