Underwater acoustic communication systems: An overview.

There are many benefits and special insights to be found in the chilly ocean and marine locations of our planet. The inquiry can't be conducted without the help of professional techniques. The most important components of the collaborative network and communication frameworks are the underwater unmanned vehicles and sensor systems. Oceans and seas that are cold due to water temperature or ice cover are discussed here in terms of the acoustic correlation and journey below the surface. We summarize, evaluate, and contrast the benefits and drawbacks of several methods, including Frequency-shift keying, Phase-shift keying, Orthogonal frequency-division multiplexing, and Code-division multiple access, for use in underwater acoustic communication. The works are also analyzed in terms of their varied character and methods of implementation, and potential areas for future research are highlighted for further study. [ABSTRACT FROM AUTHOR]
