| 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. |
