Abstract

Underwater wireless communication (UWC) is essential to military and civilian communication systems. This article aims to review relevant literature and provide insights on available methodologies and approaches in underwater wireless communication toward developing an improved hybrid underwater communication system. This work analyzes multiple modulation schemes and fading channels suitable for underwater wireless communications that can switch between optical and acoustic modes. This review aims to provide information on effective ways to achieve a better result compared to the existing approaches from related works such that an advanced approach can be developed for submarine communication Engineering. It also seeks to assist underwater communication service providers to be aware of how to bring about the actualization of improved transmission for underwater communication.
