# Sparse Recovery of Streaming Signals Using $\ell_1$-Homotopy

• Published 2014 in IEEE Transactions on Signal Processing

#### Abstract

Most of the existing sparse-recovery methods assume a static system: the signal is a finite-length vector for which a fixed set of measurements and sparse representation are available and an l1 problem is solved for the reconstruction. However, the same representation and reconstruction framework is not readily applicable in a streaming system: the signal… (More)
