In this paper, we propose, design and evaluate the performance of an angle diversity transmitter (ADT) to achieve high data rate multi-user indoor visible light communication (VLC) systems. Our proposed systems are examined with three different receivers: a wide-field of view (W-FOV) receiver, an angle diversity receiver (ADR) and an imaging diversity receiver (IMDR). A novel algorithm is introduced also to eliminate the multi-user interference that is caused by line of sight (LOS) components, since these have a great impact on VLC systems performance. The effect of multi-user interference, mobility and diffuse reflections are considered in this work. We also investigate the effect of an increase in the number of the users on our proposed systems while achieving a high data rate for each user. Our proposed systems achieve 1 Gb/s for ADT with W-FOV receiver, 2 Gb/s for ADT with ADR and 4 Gb/s for ADT with IMDR with a simple modulation technique (on–off-keying, OOK).

多用户高数据速率室内 VLC 系统
在本文中,我们提出、设计和评估角度分集发射器 (ADT) 的性能,以实现高数据速率多用户室内可见光通信 (VLC) 系统。我们建议的系统使用三种不同的接收器进行检查:宽视场 (W-FOV) 接收器、角度分集接收器 (ADR) 和成像分集接收器 (IMDR)。还引入了一种新颖的算法来消除由视线 (LOS) 分量引起的多用户干扰,因为这些分量对 VLC 系统性能有很大影响。这项工作考虑了多用户干扰、移动性和漫反射的影响。我们还研究了增加用户数量对我们提议的系统的影响,同时为每个用户实现高数据速率。
