Abstract

The invention discloses a wireless ultraviolet light communication scattering channel simulation method in a mobile scene, which is specifically implemented according to the following steps of: 1, establishing a wireless ultraviolet light communication scattering channel transmission model, and determining a scattering position of emitted photons; 2, determining the moving direction and speed of the receiving end; 3, determining the position of a receiving light cone vertex Q in the moving scene; 4, calculating the probability that the photons scattered by the scattering point Sn can reach theQ point; and 5, drawing an impulse response and path loss graph in the moving direction. By means of the method, the relation between the relative movement speed and movement direction of the wireless ultraviolet light communication nodes and scattering channel characteristics in a moving scene is studied, an impulse response and path loss graph is drawn, and a theoretical basis is provided for reducing the path loss of a receiving end and improving the signal-to-noise ratio of the receiving end.

Description

technical field [0001] The invention belongs to the technical field of wireless ultraviolet light communication, and relates to a method for simulating a scattering channel of wireless ultraviolet light communication in a mobile scene. Background technique [0002] At present, the wireless ultraviolet communication mainly uses the Monte Carlo method and the ergodic microelement method to establish the channel transmission characteristic model. At present, the Monte Carlo method is the most important method for studying the multi-scattering transmission model of ultraviolet light. The Monte Carlo method is used to analyze the scattering transmission problem, which can simulate the whole process of photon scattering transmission well, and can calculate the system path loss and simulate the impulse response. [0003] At present, the simulation research on wireless ultraviolet light communication is fixed at the receiving end, which cannot realistically describe the channel tran...
