On the Design of a High Data Rate Underwater Acoustic Receiver

In this paper, we propose a novel design for a high-speed underwater acoustic (UWA) receiver chain. Towards this objective, we introduce a novel closed-loop, adaptive, single-rate Doppler scale estimation and compensation algorithm and a novel dual-domain channel estimation and equalization technique. We validate our results and evaluate the proposed schemes using extensive simulations based on channel models generated from the analysis of the Kauai Acomms MURI 2011 (KAM11) UWA communications experiment's recording. The extensive simulations show that the proposed algorithms exhibit superior performance compared to the state-of-the-art.
