Testing OFDM Transmission Schemes for Shallow Water Acoustic Communications

Abstract

Large variability of communication properties of underwater acoustic channels, and especially strongly varying instantaneous conditions in shallow waters, is a tough challenge for the designers of underwater acoustics communication (UAC system. There is a need for developing adaptive signaling schemes that would dynamically optimize signal parameters in both physical and link layers of communication protocols. The orthogonal frequency division multiplexing (OFDM) being a multi-carrier modulation technique applied successfully in the latest standards of wireless communications, seems to be the most promising. The paper reviews general features of UAC channels, describes their statistics-based transmission model applied in wireless system design, and presents communication test performed by the authors with the use of a laboratory model of an OFDM data transmission system in both static and moving configurations of a receiver in a shallow lake. The effectiveness of matching the OFDM signaling schemes, channel coding, and transmission frame structure to current channel conditions was tested.
