固态照明是一个研究和应用快速发展的领域，这归因于这些器件的可靠性以及预期的高效率。通常用于一般照明的白色发光二极管（LED）光源也可用于数据传输，而可见光通信（VLC）是一个快速发展的研究领域。关键挑战之一是光源有限的调制带宽，通常只有几兆赫兹。然而，由于一个房间或覆盖空间通常会由一组LED进行照明，所以存在并行数据传输的可能性，并且使用光学多输入多输出（MIMO）技术对于实现高数据速率可能具有吸引力。在本文中，我们研究了非成像和成像MIMO方法：由于对称性，非成像光学MIMO系统在所有接收位置都不能正常工作，但基于成像的系统可以在所有可预见的情况下运行。模拟表明，此类系统可以在数百兆比特每秒的速率下运行，在许多情况下甚至可以达到千兆比特每秒。
Solid-state lighting is a rapidly growing area of research and applications, due to the reliability and predicted high efficiency of these devices. The white LED sources that are typically used for general illumination can also be used for data transmission, and Visible Light Communications (VLC) is a rapidly growing area of research. One of the key challenges is the limited modulation bandwidth of sources, typically several MHz. However, as a room or coverage space would typically be illuminated by an array of LEDs there is the potential for parallel data transmission, and using optical MIMO techniques is potentially attractive for achieving high data rates. In this paper we investigate non-imaging and imaging MIMO approaches: a non-imaging optical MIMO system does not perform properly at all receiver positions due to symmetry, but an imaging based system can operate under all foreseeable circumstances. Simulations show such systems can operate at several hundred Mbit/s, and up to Gbit/s in many circumstances.
