Description
technical field [0001] The invention relates to the technical field of underwater wireless optical communication, in particular to an underwater wireless optical communication system. Background technique [0002] Underwater wireless optical communication technology has attracted extensive attention from academia and industry. With the exponential growth of mobile devices and mobile services, wireless spectrum resources are becoming increasingly scarce. As a special electromagnetic band, light has the advantage of bandwidth resources that are incomparable to radio frequency bands, which makes high-speed communication possible and does not require spectrum applications. The high-performance transmitter and receiver are important components of the underwater wireless optical communication system. How to improve the communication performance of the system is one of the technical problems faced by those skilled in the art. Contents of the invention [0003] An embodiment of ...
