MIMO Visible Light Wireless Communication System Employed Camera-Based Receiver
A novel multiple-input multiple-output (MIMO) visible light communication (VLC) system is proposed, by applying multi-lights. n lights are simulated by software and different signal sequences are sent, respectively. In the receiver, camera is employed to receive the wireless signals. After that, the image processing algorithms are defined to recognize and restore the signal sequences and the n signal sequences can be recovered. The result demonstrates that the minority error codes appeared in the experiments all can be rectified accurately, and the signal sequences sent in the transmitting end all can be restored in the receiving end exactly. The presented approach evades the layout problem of lighting, the synchronization problem, and the multipath interference problem existed in the presented system based on the photodiode receiver by altering the mechanism of signal receiving. The way of transferring and receiving the signals based on multi-channels presented increases the use ratio of light source, and it possesses more practical value because of its operability.
