Abstract

Achieving reliable high speed digital communications over an underwater channel is a challenge that many scientists are trying to take up. For various applications such as remote control and data exchange, for example between an autonomous underwater vehicle and a surface vessel, the need is getting more and more important in designing reliable communications systems by means of acoustic waves. The authors focus on a coherent receiver where synchronization (timing recovery and carrier recovery) and equalization are jointly optimized
