Abstract

The GESMA is developing a high data rate acoustic link whose robustness must allow communication between a mobile and a surface vessel. The selected multi-channel blind equalizer is designed to follow strong variations of underwater acoustic channel (UWA). This patented equalizer developed by ENST-Bretagne is the heart of a digital processing whose integration on a DSP (digital signal processor) platform is currently carried out acquisition, timing, carrier and phase recovery, equalization, and decision are jointly optimized. Its validation must make it possible the GESMA to transmit real-time information to data rate higher than 25 kbps in a horizontal configuration
