Compressed sensing (CS)-based optical camera communications (CS-OCC) technology was previously studied to support accurate optical data detection with down-sampled measurements. This paper extends the CS-based OCC scheme to discuss the methods supporting dimming control functionality. Based on measurement matrices consisting of a random distribution of pseudo-noise (PN) code for sparse reconstruction, various solutions for a dimmable CS-OCC method are provided. The simulation results show that the CS-OCC scheme of Gaussian PN code with a varying mean signal shows the best data retrieval performance, while providing robust dimming control.
