Abstract

The communication channel estimation between unmanned systems has always been a concern of researchers, especially the channel estimation of broadband wireless communication and underwater acoustic communication. Due to its sparsity, more and more researchers use adaptive filtering algorithms combined with sparse constraints for sparse channel estimation. In this paper, a sparse adaptive filtering algorithm based on correntropy induced metric (CIM) penalty is proposed, and the maximum multi-kernel correntropy criterion (MMKCC) is used to replace the minimum mean square error criterion and the maximum correntropy criteria for robust channel estimation. Specifically, the MMKCC is used to suppress complex impulse noise, and the CIM is used to effectively utilize channel sparsity. The effectiveness of the proposed method is confirmed by computer simulation.
