Underwater Acoustic Propagation and Communications: A Coupled Research Program

Abstract

This work, which combined the efforts of 10 Pis at 6 different institutions, focused on combining work in small-scale physical oceanography, underwater acoustics, adaptive signal processing, and communications to bridge the gap between the capabilities of current underwater acoustic communications systems and the projected requirements for such systems in U.S. Navy CONOPS for the future. Specifically, the team focused on three main areas. These included: 1) the development of new data modulation and coding, channel estimation, adaptive equalization and decoding, and numerical optimization methods to improve the ability of underwater acoustic communications systems to transmit data reliably through complex ocean environments, 2) characterizing the acoustic propagation properties of those environments and 3) predicting the performance of acoustic communications systems in realistic ocean environments.
