Recovery of Block-Sparse Representations from Noisy Observations via Orthogonal Matching Pursuit
Jun Fang, Hongbin Li
We study the problem of recovering the sparsity pattern of block-sparse signals from noise-corrupted measurements. A simple, efficient recovery method, namely, a block-version of t…

Optimal Precoding Design and Power Allocation for Decentralized Detection of Deterministic Signals
Jun Fang, Hongbin Li, Zhi Chen +1
We consider a decentralized detection problem in a power-constrained wireless sensor networks (WSNs), in which a number of sensor nodes collaborate to detect the presence of a dete…
