Underwater communications system and method
First Claim
1. An underwater communications system for transmitting electromagnetic and/or magnetic signals to a remote receiver, comprising:
- a data input;
a digital data compressor for compressing data that to be transmitted;
a modulator for modulating the compressed data onto a carrier signal; and
an electrically insulated, magnetic coupled antenna for transmitting the compressed, modulated signals.

Abstract
An underwater communications system is provided that transmits electromagnetic and/or magnetic signals to a remote receiver. The transmitter includes a data input. A digital data compressor compresses data to be transmitted. A modulator modulates compressed data onto a carrier signal. An electrically insulated, magnetic coupled antenna transmits the compressed, modulated signals. The receiver that has an electrically insulated, magnetic coupled antenna for receiving a compressed, modulated signal. A demodulator is provided for demodulating the signal to reveal compressed data. A de-compressor de-compresses the data. An appropriate human interface is provided to present transmitted data into text/audio/visible form. Similarly, the transmit system comprises appropriate audio/visual/text entry mechanisms.
