Coherence-based sufficient condition for support recovery using block generalized orthogonal matching pursuit

Aravindan Madhavan,
Yamuna Govindarajan

Abstract: Challenge is to find the support vectors of the unknown block sparse vector with compressed measurements in an underdetermined system where the number of unknowns is more than that of measurements. To recover unknown block sparse vector, restricted isometry property (RIP) is a sufficient condition need to be satisfied. Finding the restricted isometric constant is a non-polynomial hard problem for large values of n. In this paper coherence-based recovery guarantee has been proposed to recover the support vector… Show more
