Abstract

The embodiment of the invention provides an underwater wireless optical communication system. A transmitting end comprises an audio and video signal input module, a signal conditioning circuit and a light source array. and a receiving end comprises a photoelectric detection module, a demodulation module and an audio and video signal output module, wherein the light source array is an array formedby spatial distribution of a plurality of first light emitting diodes and a plurality of second light emitting diodes; the light-emitting frequency bands of the first light-emitting diode and the second light-emitting diode are different. The photoelectric detection module comprises a photomultiplier and four avalanche photodiodes, a multiple-input-multiple-output signal transmission mode is formed, multiple diversity communication modes such as space diversity, frequency diversity and time diversity can be achieved, underwater channel fading resistance and communication performance of the system are remarkably improved, and communication performance of the system is remarkably improved.

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 ...
