Abstract

In order to solve the problems of short-range underwater communication while the position of two sides are uncertained

a non-contact transceiver devices for underwater which is based on magnetic coupling technology is designed.The transceiver device sent by ASK modulation mode

demodulated by envelope detector

C8051F020 is used to suppress the phenomenon of self-transmitting and self-receiving in order to achieve half-duplex co-communication.The experiment shows that the transceiver device is not only low cost

simple and portable

but also low power consumption

and it has a strongly practical application by effectively resolving the non-contact short-range underwater communications.
