摘要翻译：
可见光通信(VLC)是一种利用发光二极管(LED)将通信和照明结合起来的新兴技术。它被认为是一种很有前途的室内无线通信方案，可以以较低的成本部署，同时提供较高的数据速率性能。本文重点研究了一个多用户VLC系统的下行链路设计。多用户系统固有的干扰是由媒体的广播性质造成的。基于线性预编码的方案是最近提出的缓解用户间干扰的最流行的解决方案之一。本文主要研究解决最大最小信干噪比(SINR)问题的最优线性预编码方案的设计。在不同的工作条件下研究了所提出的预编码方案的性能，并与经典的迫零预编码进行了比较。仿真结果表明该方案具有较高的增益。

英文摘要：
  Visible light communication (VLC) is an emerging technique that uses light-emitting diodes (LED) to combine communication and illumination. It is considered as a promising scheme for indoor wireless communication that can be deployed at reduced costs while offering high data rate performance. In this paper, we focus on the design of the downlink of a multi-user VLC system. Inherent to multi-user systems is the interference caused by the broadcast nature of the medium. Linear precoding based schemes are among the most popular solutions that have recently been proposed to mitigate inter-user interference. This paper focuses on the design of the optimal linear precoding scheme that solves the max-min signal-to-interference-plus-noise ratio (SINR) problem. The performance of the proposed precoding scheme is studied under different working conditions and compared with the classical zero-forcing precoding. Simulations have been provided to illustrate the high gain of the proposed scheme.
