Analysis and simulation of order reflection pulse response characteristics in diffuse channel for indoor optical communication
In view of the problem that the visible light signal is easily blocked by obstacles in the transmission, the author proposed a solution that the direct link and the diffuse link alternately transmit the optical signal. Based on this scheme, this paper uses function calculation method and experimental simulation method to analyze the response characteristics of order reflection pulse in the diffuse channel of indoor optical communication. On this basis, the response characteristics of the order reflection pulse and the influence factors of the average receiving power are discussed, and they are simulated by experiments. The experiment results show that the position of the emitting light source, the angle of the emitting light θimg and the angle of the beam diffusion θmax are the influencing factors of the average receiving power.
