Abstract
We consider two uniploar OFDM techniques for optical wireless communications:
asymmetric clipped optical OFDM (ACO-OFDM) and Flip-OFDM. Both techniques can
be used to compensate multipath distortion effects in optical wireless
channels. However, ACO-OFDM has been widely studied in the literature, while
the performance of Flip-OFDM has never been investigated. In this paper, we
conduct the performance analysis of Flip-OFDM and propose additional
modification to the original scheme in order to compare the performance of both
techniques. Finally, it is shown by simulation that both techniques have the
same performance but different hardware complexities. In particular, for slow
fading channels, Flip-OFDM offers 50% saving in hardware complexity over
ACO-OFDM at the receiver.
