Research Abstract

Underwater acoustic (UWA) communication in shallow water is still challenging owing to the effects of multipaths and Doppler shift. To conduct reliable communication in shallow water, performance of UWA communication using orthogonal signal division multiplexing (OSDM) with Doppler shift correction method is considered. From both simulation and test-tank experiment, UWA communication using OSDM is found to work effectively in the UWA channel in which the effects of multipaths and Doppler shift are large.
