The following PPT file presents the technical features of A-QL code versus 2D-OFDM code. Also, we have included the performance comparison between the codes. Please download the file for more technical details.
A-QL stands for Asynchronous Quick Link, a two-dimensional multi-band color code sequential transmission protocol from a screen to camera. The A-QL is one of mode within the IEEE 802.15.7-2018 Optical Wireless Communication standard.
After the IEEE 802.15.7-2018 A-QL color code for Optical Camera Communication, 2D-OFDM is one of the next generation for Mbps data rate transmission from a screen TX to a camera.
