摘要
Compressed sensing can exactly reconstruct sparse or compressible signals. In practice, many sparse signals have block sparse structures. To recover block sparse signals, a block backtracking-based matching pursuit algorithm is proposed, which chooses possible correct atoms by using a block processing and deletes unreliable atoms by a backtracking mechanism. The proposed algorithm doesn't require the prior knowledge about the sparse structure of signal. Experiments demonstrate that the proposed algorithm outperforms some other greedy recovery methods.
