| 摘 要： | 建立了以太无源光网络接受机的行为模型,该模型包括光纤、光电探测器、跨阻放大器、限幅放大器及时钟和数据恢复电路.模型中各部分都是利用电路结构和行为特性来进行建模的,同时也对它们的噪声和抖动进行了建模,如散粒噪声、热噪声、确定性抖动和随机抖动.由于使用了行为模型,仿真速度比普通电路模型更快,同时比解析模型更准确.整个模型用C + +语言描述,在Microsoft Visual C + +6.0 中进行实现,并利用蒙特卡洛方法对系统仿真.最后建立了测试环境对模型进行验证,结果表明仿真结果与实验结果有较好的一致性.

| Abstract: | A behavior model for the receiver of the Ethernet passive optical network(EPON)is presented.The model consists of a fiber,a photodetector,a transimpedance amplifier(TIA)followed by a limiting amplifier and a clock and data recovery circuit(CDR).Each sub-model is constructed based on the architecture of a circuit.The noise and jitter in each block such as shot noise,thermal noise,deterministic and random jitter are also considered.The performance of the whole receiver can be evaluated by the simulation of th... |
