A Greedy Multistage Convex Relaxation Algorithm Applied to Structured Group Sparse Reconstruction Problems Based on Iterative Support Detection

Algorithm 3

The GM-ADM algorithm.

Given observation and the measurement matrix .

(1) Set the iteration number and initialize the set of

detected entries .

(2) while the stopping condition is not met Do

(a) if ; otherwise, .

(b) solving weighted model (3) for .

(c) support detection using as the reference.

(d) .
