WebJun 18, 2024 · The reconstruction of sparse signals from undersampled data, which belongs to the core content of compressed sensing, is discussed and several pivotal remarks are provided which indicate the recovery guarantee is much less restricted than the existing one. PDF View 3 excerpts WebIn this paper, a novel block-sparse signal recovery method is proposed based on sparse recovery of MMV. After reconfiguration, a block-sparse signal is transformed into an MMV model signal. Therefore, the block-sparse signal recovery problem is converted into a sparse recovery problem for MMV, which can be solved much more effectively. WebApr 26, 2012 · Block-Sparse Recovery via Convex Optimization Abstract: Given a dictionary that consists of multiple blocks and a signal that lives in the range space of only a few blocks, we study the problem of finding a block-sparse representation of the signal, i.e., a representation that uses the minimum number of blocks. cheney polling numbers
