Objectives: To use diversity technique to improve the Bit Error Rate (BER) performance of Underwater Acoustic Communication (UWAC). Methods/Analysis: Orthogonal Frequency Division Multiplexing (OFDM) is used in UWAC to effectively deal with the multipath propagation delay and also it produces high bitrate underwater communication. The three major factors that are considered in UWA propagation are attenuation, time varying multipath and low speed of sound. The noise that is considered in UWAC is ambient noise. Findings: To overcome the effect of multipath fading, diversity technique is used in UWC. Spatial diversity along with Maximal Ratio Combining (MRC) is found to be a better approach to improve the error performance. Novelty/Improvement: OFDM along with spatial diversity and MRC will mitigate the system against channel fading
