【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, K f=0.05, K r=10 . Even if the K f=0, because of the noise of decision threshold, there is a BER penalty when work in the burst mode.更多还原
