Joint Sparse Recovery Using Signal Space Matching Pursuit
Junhan Kim, Jian Wang, Luong Trung Nguyen +1
In this paper, we put forth a new joint sparse recovery algorithm called signal space matching pursuit (SSMP). The key idea of the proposed SSMP algorithm is to sequentially invest…
On the Fundamental Recovery Limit of Orthogonal Least Squares
Junhan Kim, Jian Wang, Byonghyo Shim
Orthogonal least squares (OLS) is a classic algorithm for sparse recovery, function approximation, and subset selection. In this paper, we analyze the performance guarantee of the…
A Sharp Condition for Exact Support Recovery of Sparse Signals With Orthogonal Matching Pursuit
JInming Wen, Zhengchun Zhou, Jian Wang +2
Support recovery of sparse signals from noisy measurements with orthogonal matching pursuit (OMP) has been extensively studied in the literature. In this paper, we show that for an…
Optimal Power Control for Transmitting Correlated Sources with Energy Harvesting Constraints
Yunquan Dong, Zhi Chen, Jian Wang +1
We investigate the weighted-sum distortion minimization problem in transmitting two correlated Gaussian sources over Gaussian channels using two energy harvesting nodes. To this en…
A Simple Proof of the Mutual Incoherence Condition for Orthogonal Matching Pursuit
Jian Wang, Byonghyo Shim
This paper provides a simple proof of the mutual incoherence condition under which K-sparse signal can be accurately reconstructed from a small number of linear…
