The orthogonal matching pursuit algorithm has a great improvement in the convergence time compared with the matching pursuit algorithm, but the matching pursuit algorithm is still used in many current scenarios where greedy algorithm is applied. In order to understand the signal reconstruction effect of greedy algorithms and to analyze and compare the advantages and disadvantages of different algorithms, this paper briefly analyzes and compares these two typical greedy algorithms from the principle to simulation, and obtains the simulation results of matching pursuit algorithm and orthogonal matching pursuit algorithm and compares the advantages and disadvantages.Read More
