Compressive Phase Retrieval via Reweighted Amplitude Flow
Liang Zhang, Gang Wang, Georgios B. Giannakis +1
The problem of reconstructing a sparse signal vector from magnitude-only measurements (a.k.a., compressive phase retrieval), emerges naturally in diverse applications, but it is NP…
Sparse Phase Retrieval via Truncated Amplitude Flow
Gang Wang, Liang Zhang, Georgios B. Giannakis +2
This paper develops a novel algorithm, termed \emph{SPARse Truncated Amplitude flow} (SPARTA), to reconstruct a sparse signal from a small number of magnitude-only measurements. It…
Solving Large-scale Systems of Random Quadratic Equations via Stochastic Truncated Amplitude Flow
Gang Wang, Georgios B. Giannakis, Jie Chen
A novel approach termed \emph{stochastic truncated amplitude flow} (STAF) is developed to reconstruct an unknown -dimensional real-/complex-valued signal from `phas…
