Update OpenSource List

The OpticalPress Team is happy to provide Open Source Codes based on IEEE 802.15.7-2018 Optical Wireless Communication (OWC) standard, the most recent international standard that includes Optical Camera Communication (OCC) technologies. We believe that the codes are beneficial for the implementation of your novel ideas as well as practical comparison purposes. We were lucky and … Continue reading Update OpenSource List

(PPT) BER measurement of A-QL

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. For your convenience, we have measured the BER performance of A-QL code. The results showed that A-QL can support the transmission distance of 4.5m with the wide … Continue reading (PPT) BER measurement of A-QL

(PPT) – BER measurement: 2D-OFDM vs A-QL

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. … Continue reading (PPT) – BER measurement: 2D-OFDM vs A-QL
