MIMO室内可见光通信系统仿真研究

摘要

In order to enhance the speed and performance of indoor visible light communication system,the paper studies the multiple⁃input multiple⁃output(MIMO)indoor visible light communication(VLC)system based on the OptiSystem software simulation. Under the conditions of different data rates,the eye⁃diagram is analyzed between the single⁃input single⁃output (SISO)indoor visible light communication system and multiple⁃input multiple⁃output(MIMO)indoor visible light communica⁃tion systems. Simulation results show that MIMO indoor visible light communication system using parallel transmission of data im⁃proves the transfer rate of the system,and enhances the performance of the system.%　　为了提高室内可见光通信系统的速率和性能，采用OptiSystem软件在不同数据速率条件下对单输入单输出(SISO)室内可见光通信系统和多输入多输出(MIMO)室内可见光通信系统进行了眼图对比分析。仿真分析结果表明：MIMO室内可见光通信系统利用数据的并行传输，提高了系统的传输速率，提高了系统的性能。
