Method and system for improving reliability of underwater blue-green laser communication

The invention discloses a method and a system for improving underwater blue-green laser communication reliability, which belong to the field of underwater wireless communication, and are characterized in that data preprocessing and peak value judgment are combined with adaptive threshold value judgment, data preprocessing and denoising are carried out on pulses of a laser communication system, peak value judgment is carried out on denoised data, and the reliability of underwater blue-green laser communication is improved. And meanwhile, recovering the laser information in combination with a self-adaptive threshold judgment mode, and finally recovering the laser system transmitting end information. According to the invention, the defects in the prior art are overcome, a good inhibition effect on underwater noise interference of laser communication is achieved, information loss caused by underwater laser refraction and scattering is effectively avoided, and the reliability of underwater laser communication is i
