Research on the Key Technologies for Underwater Image Communication System

摘要：

It is tough to achieve higher transmit speed and lower bit error rate (BER) for underwater image communication because of the complexity of the underwater acoustic channel.By researching on compression technology, orthogonal frequency division multiplexing (OFDM) technique, channel coding and interweave technology, synchronous technology, real-time underwater image communication system is built.This system can reduce BER with the ability of resisting multipath interference and can increase communication rate with the characteristic of parallel multicarrier transmission.The experiments are performed in the channel pool with depth of 1 meter and the distance between transmitter and receiver is 15 meters.The experiment results show that the system carries out realtime underwater image transmission.The image is clear, the effect is good.
