可见光通信定位集成系统仿真研究

为了提升可见光通信(VLC)定位系统的频谱和功率利用率, 文章提出了一种基于非对称限幅和直流偏置的光正交频分复用(ADO-OFDM)的VLC定位集成系统。该通信定位集成系统具有比基于非对称限幅的光正交频分复用(ACO-OFDM)的VLC定位集成系统更高的频谱利用率和比基于加直流偏置的光正交频分复用(DCO-OFDM)的VLC定位集成系统更高的功率利用率。同时, 文章还提出了一种差分修正定位算法, 所提算法较于传统的三边定位算法其具有更高的定位精度。

Abstract

In order to improve the spectrum and power efficiency in Visible Light Communication (VLC) and location system, we propose an Asymmetrically Clipped and DC-biased Optical-Orthogonal Frequency Division Multiplexing (ADO-OFDM) technique, which combines the advantages of Asymmetrically Clipped Optical-OFDM (ACO-OFDM) and DC-biased Optical-OFDM (DCO-OFDM) with higher spectrum efficiency than ACO-OFDM and higher power efficiency than DCO-OFDM. We also apply a differential correction location algorithm, which has higher positioning accuracy than the traditional three-side location algorithm.
