Abstract Details

2010, Master of Science, Miami University, Computer Science and Systems Analysis.
One major drawback of a Coherent-Optical Orthogonal Frequency Division Multiplexing (CO-OFDM) system is its sensitivity to fiber nonlinearity. It has been shown that a Volterra series based nonlinear equalizer can compensate distortion introduced by the fiber nonlinearity. One major disadvantage of Volterra series is its complexity which can be reduced by removing its “unimportant” coefficients. The resulting Volterra system is called the sparse Volterra system. The Wiener-Hammerstein model is another popular nonlinear signal processing technique with a simpler structure. In this thesis, the nonlinear distortion of a CO-OFDM system is investigated, and equalizers based on Volterra model, sparse Volterra model and Wiener-Hammerstein model are designed. This is the first attempt to apply the Wiener-Hammerstein model to compensate nonlinear distortion in optical communication systems. A comparison between predistorters and equalizers is also presented. To the best of author’s knowledge, no such a study has ever been conducted for optical communication systems.
