摘 要：The long-term goal is to significantly advance underwater acoustic communication technologies for autonomous distributed underwater networks, through innovative signal processing, coding, and navigation algorithms. Providing highly reliable and high data rate communication links will be critical towards the development of a new era of underwater distributed networks.We have three objectives in this project: (1) Advanced communication techniques of sparse channel sensing and nonbinary LDPC coding; (2) High-resolution ranging and navigation; (3) Testbed development and medium access control. We plan to develop a network testbed to illustrate the cooperative networking scenario.
