摘　　要：为了降低非线性对正交频分复用(OFDM)光纤通信系统性能的影响,采用了一种适用于OFDM光纤通信系统的电非线性后置补偿方法。此方法基于OFDM光纤通信系统中的光纤模型,采用非线性薛定谔方程(NLSE)进行非线性后置补偿,用对称分步傅里叶算法对方程进行解析,并通过数值仿真证明了该方法能够很好地解决OFDM光纤通信系统的非线性问题,提高系统性能。An electrical nonlinear post-compensation method for OFDM optical fiber communication system is proposed to reduce the impact on the system of nonlinearity. Based on the optical fiber model of the OFDM communication system, this method employs nonlinear Schrodinger equation （NLSE） to conduct the nonlinear post-compensation, and uses symmetrical split-step Fourier algorithm to analyze the equation. Numberical simulations prove that this method is efficient for improving the performance of OFDM optical communication system.
