abstract = {<p style="text-align: justify;">In this paper, we investigate truncated $ℓ_2/ℓ_{1−2}$ minimization and its associated alternating direction method of multipliers (ADMM) algorithm for recovering the block sparse
signals. Based on the block restricted isometry property (Block-RIP), a theoretical analysis is presented to guarantee the validity of proposed method. Our theoretical results
not only show a less error upper bound, but also promote the former recovery condition
of truncated ℓ<sub>1−2</sub> method for sparse signal recovery. Besides, the algorithm has been
compared with some state-of-the-art algorithms and numerical experiments have shown
excellent performances on recovering the block sparse signals.</p>},
