Submitted full papers are to be supposed to be of at least 4 pages length. The authors should submit their papers electronically, written in English, due to the given deadline, through a web upload procedure available, see http://ifsa-eusflat2021.eu/.
This document contains the instructions for preparing a camera-ready manuscript for the proceedings of ACL-2015. The document itself conforms to its own specifications, and is therefore an example of what your manuscript should look like. These instructions should be used for both papers submitted for review and for final versions of accepted papers. Authors are asked to conform to all the directions reported in this document.
This meta-paper describes the style to be used in articles and short papers for SBC conferences. For papers in English, you should add just an abstract and for the papers in Portuguese, we also ask for an abstract in Portuguese ("resumo''). In both cases, abstracts should not have more than 10 lines and must be in the first page of the paper.
This paper presents a new entropy minimization criterion and corresponding algorithms that are used for both symbol timing and carrier frequency recovery for underwater acoustic receivers. It relies on the entropy estimation of the eye diagram and the constellation diagram of the received signal. During the parameter search, when perfect synchronization is achieved, the entropy will reach a global minimum, indicating the least intersymbol interference or a restored constellation diagram. Unlike other synchronization methods, this unified criterion can be used to build an all-in-one synchronizer with high accuracy. The feasibility of this method is proven using a theoretical analysis and supported by sea trial measurement data.
