摘要

提出了一种基于离散傅里叶变换(DFT)生成奈奎斯特信号的简单有效方法，并在带宽有限的VLC-SCFDE系统中进行了实验验证。与传统的奈奎斯特信号整形相比，该方法在带宽有限的VLC-SCFDE系统中可以获得较低的计算复杂度和显著的误码率性能提高。

A discrete Fourier transform-based method for Nyquist signal shaping in VLC-SCFDE system

A simple and efficient method based on discrete Fourier transform (DFT) to generate Nyquist signal is proposed and experimentally demonstrated in a bandwidth-limited VLC-SCFDE system. Compared to the conventional Nyquist signal shaping, the proposed method can obtain a low computation complexity as well as a significant BER performance improvement in the bandwidth-limited VLC-SCFDE system.
