As an extension of MP, the proposed algorithm incorporates a new backward technique to maintain or replace the previous selected atoms in the case of coherent dictionaries. Computer simulations using Fourier dictionaries are conducted to show the effectiveness of the proposed method compared to some other sparse approximation methods.Read More
