BER Analysis of Underwater Acoustic Communication using OFDM

Abstract

Seventy-one percent of the Earth's surface is covered by water, with oceans and seas making up an astounding 96.5 percent. This indisputable fact emphasizes the importance of investigating these unexplored underwater areas for vital purposes, including researching marine life, controlling pollution, keeping an eye on natural disasters, and exploring oil and gas. Electromagnetic, optical, and acoustic waves can communicate underwater successfully; acoustic communication is the most popular option. Improved security, cost-effectiveness, and environmental sustainability are just a few of its many benefits. Even though it faces difficulties, including slow data speeds and constrained capacity, these problems are being methodically fixed. Techniques like MultiCarrier Modulation (MCM), particularly Orthogonal Frequency Division Multiplexing (OFDM), offer workable answers to these problems. This study fully covers Bit Error Rate (BER) analysis in underwater acoustic communication using OFDM and compares BER results between different modulation schemes used in OFDM.
