Problems solved by technology

Since visible light communication uses visible light as the information transmission carrier, the carrier is easily affected by occlusion and multipath effects, especially in mobile environments, because visible light is blocked for a short time and multipath effects affect the reliability of visible light communication. The synchronization method causes the visible light communication transceiver channel to frequently switch between synchronous and out-of-synchronization states, prolonging the time for communication interruption recovery and reducing the efficiency of visible light communication

Abstract

The invention discloses a visible light communication system and a synchronous detection method thereof. The provided visible light communication system comprises a sending end and a receiving end; the sending end comprises a framing module, a sending module and a simulated sending front end; the framing module is coupled with the sending module; the sending module is coupled with the simulated sending front end; the framing module is used for framing the received transmission data to form data with fixed frame length; each frame comprises a frame synchronization code, a data frame control word, a valid data length, valid data, filling data and frame check code field. In the visible light communication system, as the received transmission data are framed by the sending end to form the data with the fixed frame length, each frame of the data can be identified correctly by the receiving end, the synchronization function for data frame sending and receiving is realized, the synchronism of the visible light communication can be accordingly kept in a better manner, and the efficiency of the visible light communication can be improved.

Description

technical field [0001] The present invention relates to the field of visible light communication, in particular to a visible light communication system and a synchronous detection method thereof. Background technique [0002] Visible light communication (VLC) is an emerging wireless optical communication technology developed on the basis of white light LED technology. It uses the high-speed response characteristics of the LED device to modulate the signal to the visible light of the LED for transmission. The communication uses visible light as the information transmission carrier, which is not affected by electromagnetic interference, is environmentally friendly, has a large transmission capacity, and can realize the combination of lighting and communication. Features. Since visible light communication uses visible light as the information transmission carrier, the carrier is easily affected by occlusion and multipath effects, especially in mobile environments, because visi...
