Abstract

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.
