Channel Environment Adaptive Symbol Decision Method for Visual-MIMO Synchronization System

In the color-independent visual-MIMO communication, the synchronization method proposed previously, overcomes the speed difference between the transmitter and the receiver and synchronizes with the synchronous data frame when the transmitter sends data significantly faster than the receiving frame rate. However, this method uses only a part of the entire transmission data as information data, and most of them are used as a kind of header for synchronization. This can be regarded as a waste of data in terms of transmission data efficiency. To overcome this problem, we propose a method to improve symbol decision accuracy by using synchronous data frame.
