In this paper, a mathematical model for signal propagation through a SWA channel based on Ray tracing model is developed. Then image transmission over UWA channel is done using OFDM. The receiver performs the LS equalization to overcome the multipath problem in UWA channel. And finally, we compare the BER performance of different modulation schemes in OFDM system through the modeled under water channel.
