摘　　要：文章采用由分步傅里叶变换求解薛定谔方程的方法研究了一套应用于基于正交频分复用(Orthogonal Frequency-Divi-sion Multiplexing,OFDM)技术的光纤无线通信(Radio over Fiber,ROF)传输系统模型,对其光学传输性能进行了仿真模拟计算。分析了光纤信道中色散和非线性参数对信号传输质量的影响,指出只有进行脉冲压缩才能在光纤中传输OFDM-ROF信号。In this paper,a model for Orthogonal Frequency-Division Multiplexing（OFDM）-based Radio over Fiber（ROF） system is studied by solving the Schrodinger equation by step Fourlier transform and its optical transmission performance is simulated and calculated.The effects of the dispersion and nonlinear parameters in fiber channels on signal transmission are analyzed,indicating that OFDM-ROF signals can be transmitted in fibers only by pulse compression.
