For Beyond 5G/6G, research on non-terrestrial wireless communications (e.g., in space, underwater, etc.) is being conducted vigorously. Among them, underwater acoustic communication has a shortage of capacity due to the frequency limitation. Moreover, the arrival time of delayed waves in water is very long, ranging from a few ms to several hundred ms, which is quite different from that of terrestrial radio communications. Therefore, suppression of the delayed wave is necessary for stable communication in wideband transmission. In OFDM transmission, delayed waves are usually suppressed by inserting a guard interval (GI), but long GIs are required to support long delayed waves which causes overhead. This paper proposes a highly efficient underwater acoustic OFDM transmission scheme using blind adaptive array interference suppression. Its effectiveness is demonstrated by simulations using evaluation metrics such as bit error rate (BER) and throughput. Experiment results using large-scale water tank are also presented |
