摘要

在RZ-DQPSK调制格式下，采用递推最小二乘(RLS)和均方误差(MSE)自适应算法，采用多gsa /s采样率的并行决策反馈均衡(DFE)技术来缓解100 Gbps 1000 km长距离光放大光纤传输系统中的色散(CD)和非线性损伤。数字均衡器与电子前置放大器和ADC级联嵌入相干光波接收机中。RLS算法提供了近300公里的G652标准单模光纤的CD公差;而MSE算法只能容忍约240公里。本文的远程光传输系统仿真是在Matlab Simulink平台上进行的。

Digital lightwave receiver employing parallel-DSP-based equalization technique for 100 Gbps 1000-km RZ-DQPSK optical communication system

We demonstrate by simulation a parallel decision feedback equalization (DFE) technique at multi-GSa/s sampling rate employing recursive least square (RLS) and mean square error (MSE) adaptive algorithms to mitigate the chromatic dispersion (CD) and nonlinear impairments in 100 Gbps 1000 km long-haul optically amplified fiber transmission systems under RZ-DQPSK modulation formats. The digital equalizer is embedded in the coherent lightwave receiver in cascade with the electronic preamplifier and an ADC. RLS algorithm offers a CD tolerance of nearly 300 kms of G652 Standard Single Mode Fiber; while the MSE algorithms can tolerate only about 240 kms. Our simulation for the long haul optical transmission system is developed on the Matlab Simulink platform.
