Sparse Channel Estimation for Time-Varying MIMO Underwater Acoustic Channels at Very-High Frequencies

Published: 12 November 2014 Publication History

Abstract

In this paper, the authors present a time-varying underwater channel estimation method based on the channel sparsity characteristic. The proposed algorithm is applied to provide both an accurate and fast channel estimate to a multiple-input multiple-output (MIMO) channel and to isolate each of the channel's echoes. The technique is demonstrated in a fully controlled environment using experimental data.
