Abstract:Abstract. Infrared light communication is a kind of communication method that uses infrared ray to transmit information including voice, text, data, images and so on. In this paper, a kind of wireless communication device based on infrared light is designed, which uses the near-infrared band of 950nm to transmit voice information. The device is composed of infrared emitting device and infrared receiving device, and the relay transmitting device to make the signal be transmitted further. The infrared communicat… Show more
