Abstract- In this paper we investigate the channel capacity of
intensity modulated direct detection (IM/DD) wireless optical
communication systems for an AWGN channel with a limit on the
average transmitted optical power. It has recently been shown
that asymmetrically clipped optical orthogonal frequency division
multiplexing (ACO-OFDM) is more efficient in terms of optical
power than conventional optical modulation techniques such as
pulse position modulation (PPM). When ACO-OFDM is used, the
transmitted signal has a clipped Gaussian probability
