Liang Meng, He Jinchi, Gong Jiamin. Analysis of phase characteristics for direct-detection optical OFDM system[J]. 2011,(2):20-22. DOI: 10.13756/j.gtxyj.2011.02.015.
Theoretical analysis of signal phase characteristics in Optical Orthogonal Frequency Division Multiplexing(O-OFDM) systems is presented in this paper.A new phase equalization method is proposed on the basis of the discussion on the influence of frequency-related nonrandom noises and the other random noises on signals.The formula between system Q and OSNR is also derived.Simulation verifies this phase characteristic and the feasibility of this phase equalization method.
