Pixelated VLC-Backscattering for Self-Charging Indoor IoT Devices
Pixelated VLC-Backscattering for Self-Charging Indoor IoT Devices
Visible light communication (VLC) backscatter has been proposed as a wireless access option for Internet of Things (IoT). However, the throughput of the state-of-the-art VLC backscatter is limited by simple single-carrier pulsed modulation scheme, such as on-off keying (OOK). In this paper, a novel pixelated VLC backscatter is proposed and …
