摘　　要：本文阐述了计算机模拟等宽PFM和SWFM两种调制方式的光纤电视传输系统的原理,对于不同的调制指数、光纤带宽等参数,计算了系统非线性失真、谐波干扰等性能指标的模拟结果,同时讨论并用图直观地比较了这些结果,为系统调制方式、参数的选择,系统性能进一步提高提供了依据。The principle of computer simulation for optical fiber TV transmisson of equal width PFM and SWFM modulation ways was expounded. To parameters of different modulation index, optical fiber bandwidth etc., the simulated results of performance indexes: system nonlinear distortion, harmonic interfere cet. were computed. The results were discussed and compared directly with figures. The basis was provided for choose of system modulation ways, parameters, and enhance of system performance progressively.
