可见光通信（VLC）是一种很有前途的通信技术，为物联网铺平了道路。即将到来的工业4.0需要可靠的高速通信链路，这可以通过大量采用VLC技术轻松实现。然而，在VLC室内通信环境中，视线链路阻塞和发光二极管（LED）发射器与光电二极管（PD）接收器之间的强失准损耗是必须解决的常见问题。本文提出了一种协调多点（CoMP）传输技术来处理这两个问题，并进行了详细的评估的VLC系统性能的功能PD接收机的方向和密度的障碍物在不同的情况下。所提出的合作传输方案表明，在平均小区数据速率和中断概率性能的改善，因此，证明使用CoMP技术，以提供可靠的VLC服务在超密集的小小区的情况下室内。
Visible light communication (VLC) is a promising communication technology that paves the way to the Internet of Things. The forthcoming Industry 4.0 requires reliable high-speed communication links, which can be easily fulfilled with the massive adoption of the VLC technology. However, in VLC indoor communication environments, line-of-sight link blockages and strong misalignment losses between the light-emitting diode (LED) transmitters and the photodiode (PD) receivers are usual problems that must be tackled. This paper proposes a coordinated multi-point (CoMP) transmission technique to deal with both issues, and carries out a detailed evaluation of the VLC system performance as function of the PD receiver orientation and the density of obstacles in different scenarios. The proposed cooperative transmission scheme demonstrates an improvement in the average cell data rate and outage probability performance and, as a consequence, justifies the use of CoMP techniques to provide reliable VLC services in ultra-dense small cell scenarios indoors.
