AI Technical Summary

Problems solved by technology

The transmission medium of underwater communication is sea water, so it faces many inherent problems: Although long-wave radio communication can achieve one-way information transmission with a coverage range of thousands of kilometers, but the communication coding rate is low, the antenna size is large and power consumption is high, electromagnetic pollution is serious, And it is difficult to effectively transmit signals to deep-diving targets; blue-green optical communication has the advantages of high encoding rate and good mobility, but the transmission distance is short due to the attenuation of seawater absorption loss; acoustic wave communication is currently the most advantageous underwater communication However, the mechanical transducer used in long-distance acoustic wave communication has a large size and high power consumption, and the communication process is susceptible to noise interference; submarine optical cable communication has a long transmission distance, high encoding rate, and strong system stability, but it also faces the problem of energy supply. Bottleneck problems such as high pressure, high maintenance difficulty, and fixed communication location
