Abstract

We proposed a cascaded amplitude equalizer used for high speed visible light communications (VLC) system. With the cascaded pre-equalization circuit, the -3dB bandwidth of VLC system can be extended from 17MHz to 366MHz using a commercially available phosphorescent white LED, a blue filter and a differential outputs PIN receiver. The data rate is 1.60Gbit/s exploiting 16QAM-OFDM with 400MHz modulation bandwidth over 1m free-space transmission under pre-forward error correction (pre-FEC) limit of 3.8 × 10(-3). To our knowledge, this is the highest data rate ever achieved by using a commercially available phosphorescent white LED in VLC system.

摘要

我们提出了一种用于高速可见光通信（VLC）系统的级联幅度均衡器。通过级联预均衡电路，使用市售的磷光白色发光二极管、蓝色滤光片和差分输出PIN接收器，VLC系统的-3dB带宽可以从17MHz扩展到366MHz。在3.8×10（-3）的前向纠错（pre-FEC）限制下，通过16QAM-OFDM利用400MHz调制带宽在1m自由空间传输上实现的数据速率为1.60Gbit/s。据我们所知，这是在VLC系统中使用市售磷光白色发光二极管所实现的最高数据速率。
