Significant progress in the field of underwater communication has led to the convincing need for a lowpower and low-cost modem. In this work a high speed wireless underwater opto-acoustic communication has been demonstrated through the proposed hybrid opto-acoustic modem using Orthogonal Frequency Division Multiplexing (OFDM). The proposed hybrid modem has been simulated for transmission and reception of both optical and acoustic signals. The output signals are compared and verified with respect to the input signal both in air and water medium. The received signal strength in underwater transmission of ultrasound and light signals is compared with that of the same signals being transmitted in air. The comparison results proves the accuracy of the reception of signals by the proposed hybrid opto-acoustic modem.
