Information Theoretic Limits for Phase Retrieval with Subsampled Haar Sensing Matrices
Rishabh Dudeja, Junjie Ma, Arian Maleki
We study information theoretic limits of recovering an unknown dimensional, complex signal vector with unit norm from magnitude-only measurements of the…
Analysis of Spectral Methods for Phase Retrieval with Random Orthogonal Matrices
Rishabh Dudeja, Milad Bakhshizadeh, Junjie Ma +1
Phase retrieval refers to algorithmic methods for recovering a signal from its phaseless measurements. Local search algorithms that work directly on the non-convex formulation of t…
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 from its phaseless measurements …
Capacity Optimality of AMP in Coded Systems
Lei Liu, Chulong Liang, Junjie Ma +1
This paper studies a large random matrix system (LRMS) model involving an arbitrary signal distribution and forward error control (FEC) coding. We establish an area property based…
