	1	Position encoded asymmetrically clipped optical orthogonal frequency division multiplexing in visible light communications显示文摘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 to positive ones.In addition,encoded ACO-OFDM samples are combined with every ACO-OFDM symbol to allow the receiver to identify the position of the inverted samples.Simulation results are introduced,and it is shown that the data rates of PE-ACO-OFDM improve by 33%compared with ACO-OFDM,when a 256-quadrature amplitude modulation scheme is considered as the encoded constellation order.It is also shown that the signal to noise ratio of the proposed PE-ACO-OFDM is higher by almost 1 dB compared with the traditional ACO-OFDM.
