Abstract :
Discusses communications from a transmitter to a receiver, one or both may be mobile. The authors describe the channel simulator, which takes into account the horizontal and vertical receiver movement and the bandpass modulation to reconstruct the interference generated by multipath propagation. Those interferences represent the most difficult problem in underwater communication. The authors present some modulation schemes MPSK and MFSK with frequency hopping
