Mobile Application for Visible Light Communication Systems: An Approach for Indoor Positioning

Photonics
We explore the use of smartphones to decode data transmitted from LEDs to smartphone cameras in visible light communication (VLC) applied to indoor positioning applications. The LEDs—modified to enable rapid on-off keying—transmit identification codes or

Experimental Demonstration of 32‐PAM Optical Camera Communication Using a Low Cost and a High Cost Camera

IET Optoelectronics
This work demonstrates experimentally the feasibility of using up to 32‐PAM in rolling shutter based optical camera communication (OCC). Two different cameras have been used for OCC performance comparison, namely, a low‐cost Pi Camera V2.1 and a higher ...

TickRS: A High-Speed Gapless Signal Sampling Method for Rolling-Shutter Optical Camera Communication

Photonics
Using the rolling-shutter mechanism to enhance the signal sampling frequency of Optical Camera Communication (OCC) is a low-cost solution, but its periodic sampling interruptions may cause signal loss, and existing solutions often compromise ...
