Open publisher page 8 citations

Abstract

In recent years researchers have shown that Orthogonal frequency division multiplexing (OFDM) is also a promising technology for optical wireless communications (OWC). In this paper we evaluate the performance of direct detection Flip-OFDM with different mapping schemes in indoor OWC, visible light communication (VLC). Three OFDM techniques, namely, DC-clipped optical OFDM (DCO-OFDM), asymmetrically clipped optical OFDM (ACO-OFDM) and flip OFDM are discussed. The performance of M-QAM and M-PSK mapping schemes in Flip-OFDM are studied using simulation results.
