Study on MC-CDMA for Underwater Acoustic Networks

In this paper, multiple access technique for the physical layer of underwater acoustic (UWA) networks is discussed. Considering the characteristics of acoustical channel and UWA networks, multi-carrier code division multiple access(MC-CDMA) method is chosen as the multiple access strategy in the design of an UWA network. On this basis, a MC-CDMA multiple access scheme is proposed. The preliminary results of simulation and lab pool testing indicate that MC-CDMA technique is a feasible multiple access method for the physical layer of UWA network.
