Underwater Communications: An OFDM-system for Underwater Communications

Abstract

In the fall 2006 NTNU (The Norwegian University and Science and Technology) initiated a strategic project in cooperations with SINTEF where the aim is to gain more knowledge about underwater acoustic communications. This study is a part of this project and focuses on a system for underwater communication. A orthogonal frequency division multiplexing (OFDM) system using differential quadrature phase shift keying (DQPSK) has been defined and implemented in MATLAB. The system has been characterized through thorough simulations and testing. Initial measurements has also been carried out in order to test the developed system on a real underwater acoustic channel and the results have been analysed.
