Abstract

Transmitting data with water as the medium is called underwater communication. Electromagnetic signals are better attenuated in water than sound. Hence it is the most reliable and versatile means of communication underwater. The acoustic signals will be affected by ocean driven noise during transmission. Ambient noise is the background noise which has to be subtracted from the acoustic signal for smooth transmission. Hence the recognition and reduction of ambient noise is the essential part of underwater signal transmission. Studies and research are being carried out extensively in this area. There are many works reported and the research is still in progress. This literature survey presents the work done on the research front of ambient noise affecting acoustic signals.

水声信号环境噪声分析的文献综述

以水为介质传输数据称为水下通信。电磁信号在水中比在声音中衰减得好。因此，它是水下最可靠、最通用的通信手段。声信号在传输过程中会受到海洋噪声的影响。环境噪声是为了使声信号顺利传输而必须从声信号中去除的背景噪声。因此，环境噪声的识别与降噪是水下信号传输的关键环节。在这方面正在进行广泛的研究和研究。目前已有许多研究报道，研究仍在进行中。本文综述了环境噪声对声信号影响的研究进展。

期刊介绍： Computational science and engineering is an emerging and promising discipline in shaping future research and development activities in both academia and industry, in fields ranging from engineering, science, finance, and economics, to arts and humanities. New challenges arise in the modelling of complex systems, sophisticated algorithms, advanced scientific and engineering computing and associated (multidisciplinary) problem-solving environments. Because the solution of large and complex problems must cope with tight timing schedules, powerful algorithms and computational techniques, are inevitable. IJCSE addresses the state of the art of all aspects of computational science and engineering with emphasis on computational methods and techniques for science and engineering applications.
