A simple channel estimation （UE） scheme, which is pilotaided with just a little number oI pilots inserted in the Itrst half part of the subcarriers, is proposed and simulated for resisting the fiber dispersion in optical orthogonal fre quency division multiplexing （OFDM） systems. The simulation resu...
