Abstract
This paper discusses the impact of pulse shaping filter on the performance of orthogonal frequency division multiplexing (OFDM) based visible light communication (VLC) systems. Particularly, direct current biased optical OFDM (DCO-OFDM) with square-root-raised-cosine (SRRC) pulse shaping filters is investigated. The bit-error-rate (BER) performance of the system is evaluated for different excess bandwidth parameters (roll-off factors) and compared with the performance with rectangular pulse shaping filter through Monte Carlo simulations.
