Özet

Underwater Communication is one of the most difficult challenges facing researchers. OFDM technique has been used widely in 4G communication systems, and recently it was approved to be successfully implemented in 5G. Many researchers have improved the Underwater wireless communication system including Acoustic communication using the OFDM technique. We applied the Cyclic Prefix in this study to improve the underwater communication system. We started by studying the effects of Rician fading based on the OFDM system on the wireless channel. Then we analyzed the Bit Error Rate (BER) of the system in several scenarios, by applying the AWGN, Rician fading, and absorption factor to simulate the underwater channel.
