Affine phase retrieval for sparse signals via minimization
Meng Huang, Shixiang Sun, Zhiqiang Xu
Affine phase retrieval is the problem of recovering signals from the magnitude-only measurements with a priori information. In this paper, we use the minimization to explo…

No existence of linear algorithm for Fourier phase retrieval
Meng Huang, Zhiqiang Xu
Fourier phase retrieval, which seeks to reconstruct a signal from its Fourier magnitude, is of fundamental importance in fields of engineering and science. In this paper, we give a…

Strong convexity of affine phase retrieval
Meng Huang, Zhiqiang Xu
The recovery of a signal from the intensity measurements with some entries being known in advance is termed as {\em affine phase retrieval}. In this paper, we prove that a natural…
