摘要

本文提出了一种采用OFDM调制的VLC(可见光通信)系统接收机的设计。根据该ofdm系统设计规范,该接收机包括时域和频域转换、同步和均衡功能。OFDM同步的功能包括边界估计、采样时钟偏移估计和补偿。均衡部分包括信道效应估计和数据恢复的频域均衡器。

Design and implementation of the OFDM receiver for visible-light communication
This paper presents a receiver design for the VLC (Visible Light Communication) system using OFDM modulation. Based on this design specification of OFDM-based system, this receiver comprises of a time and frequency domain conversion, synchronization and equalization functions. The functions of OFDM synchronization contain boundary estimation and sampling clock offset estimation and compensation. Equalization section contains the channel effect estimation and frequency domain equalizer for data recovery.
