Phase Retrieval for Signals in Union of Subspaces
M. Salman Asif, Chinmay Hegde
We consider the phase retrieval problem for signals that belong to a union of subspaces. We assume that amplitude measurements of the signal of length are observed after passin…
Sparse Recovery of Streaming Signals Using L1-Homotopy
M. Salman Asif, Justin Romberg
Most of the existing methods for sparse signal recovery assume a static system: the unknown signal is a finite-length vector for which a fixed set of linear measurements and a spar…
Channel Protection: Random Coding Meets Sparse Channels
M. Salman Asif, William Mantzel, Justin Romberg
Multipath interference is an ubiquitous phenomenon in modern communication systems. The conventional way to compensate for this effect is to equalize the channel by estimating its…
Dynamic Updating for L1 Minimization
Muhammad Salman Asif, Justin Romberg
The theory of compressive sensing (CS) suggests that under certain conditions, a sparse signal can be recovered from a small number of linear incoherent measurements. An effective…
