Clemente, José Paris, Pablo Otero] Acoustic or ultrasonic transmission is the preferred alternative for underwater communications. Power is not an unlimited resource in the underwater environment. Moreover the underwater acoustic channel is subject to severe slow and fast fading. High transmission power is needed so that a fair BER is achieved. A power control policy is, therefore, of paramount importance. This communication explores the benefits of using power control in underwater communications, when gamma/Ricean channels are considered. Simulation results are presented that suggest which channels are more appropriate for the power control to be applied, and estimate the amount of expected power saving.
