In this paper the two Optical Wireless orthogonal frequency division multiplexing (OFDM) techniques in intensity modulated/direct detection (IM/DD) optical systems are compared. These are asymmetrically clipped optical OFDM (ACO-OFDM) and DC biased optical OFDM (DCO-OFDM). The comparison is done by...
We propose a layered asymmetrically clipped optical fast orthogonal frequency division multiplexing(ACO-FOFDM)scheme for intensitymodulated and directdetected(IM/DD)systems. Layered ACO-FOFDM can compensate the weaknessof conventional ACO-FOFDM in low spectral efficiency. For FOFDM system, the ...
