Performance evaluation technique for screen-to-camera-based optical camera communications

Abstract

The increasing development and utilisation of optical camera communications offer an excellent opportunity for the implementation of the smartphone-to-smartphone-based visible light communications (S2SVLC) system. In this study, the authors experimentally demonstrate that the S2SVLC system can support high-quality multimedia transmissions by the investigation of the mean square error estimation, peak signal-to-noise (PSNR) degradation, bit error rate (BER), and data rate achieved. The experimental analysis has been carried out for different typical practical background illuminations (i.e., normal illumination and dark condition), distances, tilting, and rotation angles. The PSNR and BER are determined for different frame sizes in the S2SVLC system to provide an insight of system performance. Those results indicate that the data transmission at different conditions significantly impacts the system's performance.
