¿µ¹®³»¿ë¿ä¾à | OOK (On-Off Keying) is a simple modulation, which is widely used in communication systems. OOK scheme uses zeros crossing to check the on/off value of the image to decode data. MIMO-OOK scheme is a new design, which uses multiple LEDs to transmit data to increase data rate. This scheme support the challenging technical issues such as code detection based on RoI detection algorithms. Besides that, the data frame structure is proposed with LED-ID parameter and NODE ID. | ||
