Sparse Signal Recovery by Stepwise Subspace Pursuit in Compressed Sensing
In this paper, an algorithm named stepwise subspace pursuit (SSP) is proposed for sparse signal recovery. Unlike existing algorithms that select support set from candidate sets directly, our approach eliminates useless information from the candidate through threshold processing at first and then rec...
