Use of Inertial‐Type Variable‐Reluctance Transducers in Underwater Telephony

Piezoelectric Materials Used in Underwater Acoustic Transducers

Underwater Telephony : Past, Present and Future

Underwater telephones allow divers to talk to each other or to a supervisor on the surface. This paper outlines the principles of various systems used in the past, how they have improved for use at present, and what developments are likely in the future.

Chaos-Based Underwater Communication With Arbitrary Transducers and Bandwidth

In this work, an enhanced differential chaos shift keying (DCSK), based on a first order hybrid chaotic system, is being proposed for a high reliability underwater acoustic communication system. It can be integrated into systems that use standard existing transducers. We show that a coherent operation between the received signal and the time reversal of the basis function in a first order hybri...
