Abstract Aiming at the influence of underwater acoustic channel (UAC) profile difference on the performance of underwater acoustic communication. a variable observation window length blind equalization detector (VOWL-BED) is proposed in this paper. Compared with the existing methods. the observation window length (OWL) of the proposed VOWL-BED can be dynamically regulated on the basis... https://macorners.shop/product-category/wooden-family-puzzle/
