本文采用四个LED和四个光电探测器对基于室内多输入多输出（MIMO）的可见光通信系统进行了误码率分析。对所述MIMO系统进行了仿真，其中研究了LOS、LOS加第一反射（L-R1）和LOS加沿着第一反射和第二反射（L-R1-R2）的BER。已经考虑了两种类型的配置，在第一种配置中，光电探测器之间的间隔为10 cm，而在第二种配置中，间隔已增加到20 cm。已经发现，对于LOS和（L-R1）信道，配置2的BER比配置1的BER分别好10 dB和12 dB。但对于L-R1-R2，配置2的BER比使用配置1的BER提高了30 dB。分别通过仿真LOS、L-R1和L-R1-R2信道矩阵的条件数对结果进行了验证。
In this paper, BER analysis of indoor multiple-input multiple-output (MIMO) based visible light communication (VLC) system has been performed using four LEDs and four photodetectors. Simulation has been done for said MIMO system in which BER of LOS, LOS plus first reflection (L-R1) and LOS plus first reflection along with second reflection (L-R1-R2) have been investigated. Two types of configuration have been considered, in the first one, the separation between photodetectors is 10cm whereas in the second configuration, separation has been increased to 20cm. It has been found that BER for LOS and (L-R1) channel is better for configuration 2 as compared with BER for configuration 1 by 10dB and 12dB respectively. But for L-R1-R2, BER for configuration 2 improves by 30dB than that using configuration 1. The results have been verified through simulated condition number of LOS, L-R1 and L-R1-R2 channel matrix respectively.
