摘要：

To solve the large fluctuation problem of signal-to-noise ratio of optical signals on the received plane in the indoor visible light communication system and improve the overall performance of the visible light communication system, a light source power optimization algorithm for the visible light communication system based on the swarm optimization algorithm — fireworks algorithm is proposed. The algorithm takes the signal-to-noise ratio factor of the wireless light-receiving plane as the optimization goal, optimizes the transmit power of each LED(Light Emitting Diode)light source, obtains the optimal signal-to-noise ratio factor on the receiving plane, and effectively reduces the optical signal fluctuation of the light-receiving plane. The results show that when the number of light sources is 16 point light sources, the signal-to-noise ratio factor on the receiving plane is reduced by 45% compared with the equal power light sources, which significantly improves the fluctuation amplitude of the received optical signal, thereby ensuring that the optical communication users at different positions can obtain the same communication quality. This method is suitable for any number and position of LED light sources, and is not limited by the number and positions of light sources. The comparative analysis shows that the signal-to-noise ratio factor of the receiving plane is smaller and the uniformity of the signal-to-noise ratio distribution is better with the increase of the number of light sources. © 2024 Chinese Institute of Electronics.
