Tutorial 2

Title

Signal Waveform Design for Underwater Acoustic Communications

Presenters

Dr. Charalampos C. Tsimenidis 

Prof. Bayan S. Sharif

Abstract

 

The tutorial will cover the design of signalling waveforms that are suitable for utilisation in underwater acoustic (UA) modems. These will include PN sequences with low auto and crosscorrelation properties, chirp design, in conjunction with pulse shaping and modulation schemes such as orthogonal frequency division multiple access (OFDM), direct sequence and multicarrier code division multiple access (DS- and MC-CDMA). The tutorial will also address underwater channel modelling and simulation methodologies that are useful in evaluating "dry" performance of UA systems. Furthermore, the design of receiver algorithms will be considered that utilise adaptive receive arrays, carrier-phase and symbol timing recovery, Doppler compensation and multi-user detection methodologies. The tutorial is suitable for modem engineers with limited or no experience in this area to assist them in the design of UA based communication systems.
