Indoor optical wireless systems provide an attractive alternative for realizing next generation Wireless Local Area Networks (WLANs). In this paper, the potential of non-directed, equalized optical wireless systems is theoretically investigated, taking into account the indoor channel impulse response and the characteristics of ambient light noise and thermal noise at the receiver. Three modulation schemes, pulse-position-modulation and on-off keying and pulse amplitude modulation, are combined with appropriate equalization methods in order to mitigate the effect of inter-symbol interference induced by the infrared channel.
