In this paper, the impact of clipping noise on optical
wireless communication (OWC) systems employing orthogonal
frequency division multiplexing (OFDM) is investigated. The
two existing optical OFDM (O-OFDM) transmission schemes,
asymmetrically clipped optical OFDM (ACO-OFDM) and directcurrent-
biased optical OFDM (DCO-OFDM), are studied. Time
domain signal clipping generally results from direct current
(DC) biasing and/or from physical limitations of the transmitter
front-end.
