Performance Evaluation of Optical Burst-Mode Receiver Based on Peak-Detector in Adaptive Threshold Control Circuit
-
摘要: 在考虑判决阈值的衰落时间和噪声特性对光接收机性能的影响后,提出了一种分析突发模式光接收机误码性能的综合模型,并分析了与传统的交流耦合光接收机相比较时,突发模式光接收机的灵敏度损失.Abstract: This paper purposes a theoretical analysis of the BER performance of burst-mode receiver. Considering two inherent factors, decay time constant and noise characteristic of the adaptive decision threshold, a comprehensive model to analyse the performance of burst-mode receiver is proposed. The theoretical model explains the burst-mode receiver's sensitivity penalty and agrees with the experiment result. The power penalty is about 2.3 dB at a BER of 10-9 compared with convention receiver in the condition of continue mode when n=23,Kf=0.05,Kr=10. Even if the Kf=0, because of the noise of decision threshold, there is a BER penalty when work in the burst mode.
