摘要
利用LED光源的快速调制特性,可实现照明和通信一体的室内可见光通信(VLC)。针对系统容量提升和多径干扰的消除问题,提出一种采用空时编码的多输入多输出(MIMO)系统结构的VLC方案。
The integration of indoor lighting and communications can be realized by using the rapid modulation characteristic of LED lights. The current key problems to the practical use of VLC are further ascension of system capacity, network integration and setup of standards. A method of space-time coding based MIMO-VLC system structure is provided here to ascend the capacity and mitigate multipath interferences as well.
