Underwater wireless optical communication optical channel simulation method and simulation system

Abstract

The invention discloses an underwater wireless optical communication optical channel simulation method and a simulation system. The method includes the steps of: selecting the type of light source to be simulated, generating light pulses, defining the initial position of the photon and the current direction cosine; and according to different water quality The type defines different water quality parameters; randomly selects the optical path, scattering angle and azimuth angle, etc., updates the photon weight, and simulates the channel transmission of photons under the selected water quality conditions; marks and counts the detected photons at the receiver. The present invention can solve the problems that underwater light field data is difficult to collect and test, and the overall system design and verification of the underwater optical communication system is difficult, and provides system simulation tools for designers, fully considers various parameters of the underwater optical communication system, and can The project needs to change the parameters to meet the engineering design requirements.
