Smart Acoustic Network Using Combined Fsk-Psk, Adaptive Beamforming and Equalization

Abstract

Our long-term objective is a smart acoustic network for multiple underwater vehicle operation, with integrated communication and positioning capability. To do so, a new generation of Coherent Path Beamformer would act as a network decoder and arbitrator for data communication and long (short) base line. Also, wireless communication to shore would be available for control and real-time data transfer. Finally, the underwater vehicles will be carrying an improved version of the compact low-cost Acoustic Modem. This concept requires the network to be synchronous. The concept is to make the most efficient use of time and frequency band.
