摘要

本文评估了基于ofdm的强度调制/直接检测(IMDD)调制技术在可见光通信(VLC)系统中的应用。评估的技术是不对称剪切光OFDM (ACO-OFDM)，直流(DC)偏置光OFDM (DCO-OFDM)和不对称剪切直流偏置光OFDM (ADO-OFDM)。根据误码率(BER)对不同类型的M-QAM调制技术进行了评估和比较。结果表明，与传统的DCO-OFDM和ADO-OFDM方案相比，ACO-OFDM总体上具有更好的性能。

BER Performance of OFDM-Based Visible Light Communication Systems

In this paper, OFDM-based techniques designed for Intensity Modulation/Direct Detection (IMDD) modulation applied to Visible Light Communications (VLC) systems are evaluated. The evaluated techniques are Asymmetrically Clipped Optical OFDM (ACO-OFDM), Direct Current (DC) Biased Optical OFDM (DCO-OFDM), and Asymmetrically Clipped DC Biased Optical OFDM (ADO-OFDM). These techniques are evaluated and compared for different types of M-QAM modulation in terms of Bit Error Rate (BER). It is shown that ACO-OFDM, in general terms, presents a better performance compared to the conventional DCO-OFDM and ADO-OFDM schemes.
