In mobile optical camera communication (MOCC) system, more than one LED is used to simultaneously illuminate and communicate. In the letter, the MOCC system with multi-LEDs and a mobile receiver is experimentally investigated. To avoid the signal interference between two LEDs and alleviate the performance degradation caused by the movement of the receiver, multi-column matrices selection (MCMS) combined with k-means based decoding (KMD) scheme is proposed and experimentally demonstrated. The experimental results show that, the proposed scheme can achieve the bit error ratio (BER) of $8.74\times 10^{-6}$ at the moving speed of 20cm/s. And the data rate is 4.2 Kb/s.

结合k-Means方案的多列矩阵选择用于带多LED的移动OCC系统

在移动光学相机通信（MOCC）系统中，多个LED用于同时照明和通信。在信中，对具有多个LED和一个移动接收器的MOCC系统进行了实验研究。为了避免两个LED之间的信号干扰并减轻由于接收器的移动而导致的性能下降，提出了多列矩阵选择（MCMS）并结合了基于k均值的解码（KMD）方案，并进行了实验证明。实验结果表明，该方案可以达到 $ 8.74 \次10 ^ {-6} $ 以20cm / s的移动速度 数据速率为4.2 Kb / s。
