In shallow water, since the propagation path of an acoustic wave exists in multiplex, the transfer of information is usually difficult. On the other hand, phase conjugate wave has the property converged on a sound source location even in shallow water and an inhomogeneous medium. A communication simulation of the information that utilized the phase conjugate wave was then performed. Phase modulation was added to the probe wave sent from the sound source, and the signal was reradiated from the array. This not only converged the emitted acoustic wave on the sound source location, but the phase of the converging wave changed in proportion to the modulation phase.
