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.

基于屏幕到相机的光学相机通信的性能评估技术

光学相机通信的不断发展和利用为基于智能手机到智能手机的可见光通信（S2SVLC）系统的实施提供了绝佳的机会。在本研究中，作者通过对均方误差估计、峰值信噪比 (PSNR) 劣化、误码率 (BER) 和数据速率的研究，实验证明 S2SVLC 系统可以支持高质量的多媒体传输实现了。针对不同的典型实际背景照明（即正常照明和黑暗条件）、距离、倾斜和旋转角度进行了实验分析。PSNR 和 BER 是针对 S2SVLC 系统中的不同帧大小确定的，以提供对系统性能的洞察。
