Description

technical field [0001] The invention belongs to the technical field of optical communication equipment, and more specifically relates to an underwater wireless communication system with dual light sources. Background technique [0002] The ocean contains rich and valuable resources. With the continuous deepening of ocean exploration research, underwater communication technology has quickly become a research hotspot. At present, underwater electromagnetic wave communication and underwater acoustic communication are the most widely used communication technologies for underwater communication. The serious attenuation of electromagnetic waves in water leads to short transmission distances, and the multipath effect and time-varying effect of sound in water lead to slow transmission rates. Neither of them can better meet the growing demand for underwater data communication. Underwater optical communication has the advantages of high bandwidth and high speed, which makes up for th...
