Phase Shift Method

On the basis of the carrier has a low frequency in underwater electric current communication, carrier phase shift network, low frequency wide band phase shift network and multiplier circuit were designed to realize the single side-band (SSB) modulation. The circuits were designed and debugged. Through testing the actual circuits, sideband suppression ratio obtains 36dB which can satisfy the underwater electric current communication system. It will be stated reference on actual application for SSB modulation with low carrier frequency using phase shift method.
