Abstract

In this letter, we propose a frequency-domain improved proportionate normalized least mean square based sparse direct adaptive equalization (FD-IPNLMS-SDAE) algorithm for underwater acoustic communication. Compared with the existing methods, the proposed algorithm is implemented in the frequency domain, which not only significantly reduces the complexity, but also has the convergence performance advantage of the sparse algorithm. Simulation results verify the advantages of the proposed algorithm over the existing approaches.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
