Cooperative Transmission for Underwater Acoustic Communications
—Underwater acoustic channel usually has low data rate, long propagation delay, severe multipath effect, and time varying fading. Cooperative transmission is a new wireless communication technique in which diversity gain is achieved by utilizing relay nodes as virtual antennas. In this paper, we investigate cooperative transmission techniques for underwater acoustic communications. First, we study the performance of several cooperative transmission schemes, originally designed for radio communications, in the underwater scenario. Second, taking advantage of the low propagation speed of sound, we design a new wave cooperative transmission scheme. In this scheme, the relay nodes amplify the signal received from the source node, and then forward the signal immediately to the destination. The goal is to influence the multipath effect at the receiver. Third, we derive a performance upper bound for the proposed wave cooperative transmission scheme. The simulation results show that the pro...
