Abstract

The invention discloses an intelligent underwater wireless optical communication system. A mechanism of self-adaptively detecting the channel environment by a receiver and the thought of updating a modulation coding format by a feedback sending end are introduced to overcome the defect that the traditional underwater visible optical communication system is confined to the limited rate of the limited scene, the receiver is more intelligent, the instant channel condition can be judged according to the statistic feature of the receiving signal, thereby making out a feedback opinion report to a sending device; the system is provided with the self-adaptive performance through the feedback channel, the stable work in the changed environment can be guaranteed, and the system has important significance for the actual application.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an intelligent underwater wireless optical communication system. Background technique [0002] Due to the complexity of the marine environment and the immaturity of marine exploration technology, human understanding of the ocean is still quite limited, and many sea areas are still in an unknown state. Therefore, it is of great significance to develop advanced marine detection technology, and underwater communication technology is particularly important as a key technical support for controlling underwater vehicles and sensors and realizing mutual data transmission between systems. In view of the constraints of wired communication technology (optical fiber, copper cable communication) on the mobility of underwater equipment and its cost increases with the increase of transmission distance, wireless communication is more suitable for underwater operations. In the cat...
