Estimating the term…
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.
An underwater communications system comprising:
The underwater communication system of claim 13, wherein speech synthesis is used to reconstruct audible speech at said remote receiver.
The underwater communications system of claim 15, wherein at least one of said plurality of intermediate transceivers is above water and is operable to relay a signal from said transmitter to said remote receiver through an air propagation path.
The underwater communications system of claim 16, wherein at least one of said plurality of intermediate transceivers is mobile.
The underwater communications system of claim 18, wherein said above water station comprises an electrically coupled antenna.
