2D-OFDM for Optical Camera Communication

OFDM is well-known for LiFi; however, it is still fresh advanced waveform for OCC. This post shares an implementation of 2D-OFDM for Screen-to-Camera communication system in which a massive number of display cells brings a great advantage for communication. A full journal version of this topic is available online at IEEE Access here. System Architecture … Continue reading 2D-OFDM for Optical Camera Communication

Software-defined Configuration method for OCC Systems

The purpose of the post is to specify the PIB attributes for configuring a particular OCC PHY mode. Any OCC PHY mode is co-existing with the others and recognizable by a specific receiver once the PIBs are specified. The configuration of PHY-PIB attributes is software-defined (App-based). Without using PHY-frame overhead, the App-based configuration is communication … Continue reading Software-defined Configuration method for OCC Systems

A comparison between OCC standardization groups within IEEE 802.15

This post briefly reviews the current status of standardization groups within IEEE 802.15 There are IEEE standards covering the optical spectrum, IEEE 802.15.7-2011 std., known as VLCIEEE 802.15.7m std., (publication in 2018, as expected), including OCC modesIEEE 802.15.13 std., (ongoing), adding LiFi (IEEE 802.15.7-2011 std. is also the base document as IEEE 802.15.7m)IEEE 802.11, introducing LiFi to 802.11IEEE 802.15 … Continue reading A comparison between OCC standardization groups within IEEE 802.15
