资源说明:A PE-ACO-OFDM (Position-Encoded Asymmetrically Clipped Optical Orthogonal Frequency Division Multiplexing) signaling scheme for intensity modulation and direct detection is introduced in this paper, where the anti-asymmetry characteristics of ACO-OFDM are exploited to improve the rate of data transmission. This is achieved by reducing the symbol duration of the ACO-OFDM signal, where only the first half of ACO-OFDM is used to transmit the ACO-OFDM data symbol after inverting its negative samples
