Sparse representation of signals has many important applications in signal processing. However, this issue is well known as a complex and NP problem, which is a key factor to depress the application and progress of sparse decomposition. In this work, seeker optimization algorithm(SOA)- based method is used to search for the best matching atoms in sparse decomposition. For comparision, the conventional matching pursuit (MP) method and two versions of PSO algorithms are also consid- ered in the simulation studies. The simulation results show that the proposed approach is an effective and reliable technique for time-frequency atom decomposition. |
