摘　　要：介绍了衡量接收特性的误码函数和Q因子,并以此为基础对突发接收模块中影响接收特性的因素,如判决电平偏离理想值、信号的消光比、信号间干扰、带宽滤波效应等进行了研究分析,对突发接收模块的设计具有重要意义。The BER function and Q-factor to evaluate the receiver are introduced. Based on this function, an in-depth analysis on the BER performance of burst-mode receiver has been carried out. The decision threshold deviated to the ideal value, extinction ratio of the signal, intersymbol interference, and the bandwidth of the filter in the receiver have been considered. All these are important to design the burst-mode receiver.
