Performance of optical OFDM systems using new PAPR reduction approach
(EBSCO Publishing., 2012-03)
The major drawback of optical orthogonal frequency division multiple access (OFDM) system is their inherent intensity noise and peak average power ratio (PAPR). We introduce a new direct detection receiver based on PAPR ...
