Abstract
For ocean buoys, the most effective information transmission link is the space-based link. Traditional buoys all float on the ocean surface, by contrast, submerged buoys have a higher security. However, since it submerges below the sea surface, the biggest problem is the high dynamic attenuation of seawater channel. This paper proposes a novel method which can overcome the highly dynamic channel characteristics. The channel state is predicted by the reflected wave received by an assisting receiver. According to the predicted channel states, the phase shift and amplitude attenuation caused by seawater are pre-compensated at the transmitter. Computer simulation results are presented to illustrate the effectiveness of the proposed method.
