In this paper, adaptive importance sampling (is) techniques is used to estimate the crosstalk and the BER of the WDM system model consisting of wavelength routing device and optical receiver.

本文采用自适应重要性采样(IS)方法，推导得出由波长路由器件和光接收机构成的WDM系统模型的串扰和误码率。

To overcome the signal distortion caused Crosstalk code, we must increase the equalizer in the receiver to compensate channel properties send resume correct sequence.

为了克服码间串扰所带来的信号畸变，必须在接收端增加均衡器，以补偿信道特性，正确恢复发送序列。
