The block orthogonal matching pursuit (BOMP) algorithm aims to recover block sparse signals whose non‐zero components have a block structure. Sensing and measurement dictionaries are alternatively optimised to have small inter‐ and sub‐block mutual coherences. The computational complexity of the proposed algorithm is low. With the designed dictionaries, the performance of the BOMP algorithm improves.
