摘　　要：采用数值仿真的方法对几种使用在10Gb/s光通信系统中的电色散补偿(EDC)均衡器的性能进行了研究,包括判决反馈均衡器、线性均衡器、最大似然序列估计器(MLSE)。仿真结果表明MLSE的性能最好,但由于它不易实现,可以采用判决反馈均衡器替代,这对实际系统的设计具有参考价值。We study the performances of several electrical dispersion compensation （EDC） equalizers with the numerical simulation in 10Gb/s optical communication system. The EDCs that are analyzed include decision feedback equalizer （DFE）, linear equalizer （LE）, and maximum likelihood sequence estimator （MLSE）.The results of simulation indicate MLSE have the best performance, but due to the difficult of its implementation, we can use the DFE. The results are helpful to design a practical system.
