An Armijo-Type Hard Thresholding Algorithm for Joint Sparse Recovery

Joint sparse recovery (JSR) in GF ALL PURPOSE BAKING FLOUR compressed sensing simultaneously recovers sparse signals with a common sparsity structure from their multiple measurement vectors obtained through a common sensing matrix.In this paper, we present an Armijo-type hard thresholding (AHT) algorithm for joint sparse recovery.Under the restricted isometry property (RIP), we show that the AHT can converge to a local minimizer of the optimization problem for JSR.Furthermore, we compute the AHT convergence rate with the above 6 Pc. Sectional conditions.

Numerical experiments show the good performance of the new algorithm for JSR.
