This paper proposes a doubly-selective channel simulator for underwater acoustic communications (UWACs), where doubly-selective environment corresponds to time and frequency selective channel environment. The proposed channel simulator can simulate severe doubly-selective environment and large signal frequency band-width to center carrier frequency ratio inevitable in UWACs environment owing to carrier frequency band sampling. First, this paper proposes a principle of the doubly-selective channel simulator for UWACs and its applications in discrete-time channel models. Next, this paper indicates performance bench-mark channel model in order to evaluate several wireless transmission technologies. Finally, computer simulation results confirm that the proposed doubly-selective channel simulator using the bench-mark channel model can simulate actual experimental environment of UWACs.
