This paper describes source depth estimation in shallow water environments using a Horizontal Line Array of hydrophones on the sea bottom. A method based on modal propagation, usi...
In this paper, we propose an algorithm to improve the performance of the mu-law PNLMS algorithm (MPNLMS) for nonsparse impulse responses. Although the existing MPNLMS algorithm wa...
