MIMO Architecture for Optical Camera Communications

The Journal of Korean Institute of Communications and Information Sciences, 2017
Compare with other communication system based RF technology, Optical Camera Communication (OCC) has limitation on data rate due to the low frame rate of camera. The limitation on data rate can be solved with multiple-input and multiple-output (MIMO) technology; and it is the final target of all researches on OCC.
