Abstract
The implementation of indoor visible light communication (VLC) systems using a direct current-biased optical orthogonal frequency division multiplexing (DCO-OFDM) scheme is investigated in this paper. The main contribution of this work is to analyze the VLC system using Simulink design. Simulink design uses blocks that are much easy and deliver optimized results for hardware implementation. The system analysis comprises, first the effect of signal scaling and biasing operation on the peak to average power ratio (PAPR) which is a major drawback in OFDM based VLC system. Second the use of the channel estimation for the received signal. Simulation results show that the PAPR is significantly reduced by employing the signal scaling combined with biasing operation. Furthermore, the bit error rate (BER) can be reduced by utilizing channel estimation algorithms such as minimum mean square error (MMSE) and least squares (LS).
