Abstract: PURPOSE: A modulation method for low power communication in an underwater sensor network and a transmitting device using the same are provided to transmit a PSK signal to only a half of a symbol signal and process the other half as a silence section. CONSTITUTION: An underwater sensor network modulates a PSK signal into two of orthogonal symbols to transmit the modulated symbols.
