Deyuan Chang,Fan Yu,Zhiyu Xiao,Nebojsa Stojanovic,Fabian N. Hauske,Yi Cai,Changsong Xie,Liangchuan Li,Xiaogeng Xu,Qianjin Xiong +9 more
TL;DR: The first layered decoding for LDPC convolutional codes designed for application in high speed optical transmission systems was successfully realized.
Journal ArticleDOI
Intrachannel Nonlinearity Compensation by Inverse Volterra Series Transfer Function
Ling Liu,Liangchuan Li,Huang Yuanda,Kai Cui,Qianjin Xiong,Fabian N. Hauske,Changsong Xie,Yi Cai +7 more
TL;DR: In this paper, a new electronic nonlinearity compensation scheme based on inverse Volterra series transfer function (VSTF) is proposed, which shows 1 dB improvement in Q-factor with a 256 Gb/s polarization-division-multiplexed 16-level quadratic amplitude modulation format.
Journal ArticleDOI
Real-Time Demonstration of Homodyne Coherent Bidirectional Transmission for Next-Generation Data Center Interconnects
TL;DR: In this paper, a homodyne coherent detection in a short-distance data center interconnect with bidirectional fiber transmission was proposed and demonstrated with a successful real-time demonstration with 600-Gb/s DP-64QAM using uncooled large-linewidth DFB lasers.
Journal ArticleDOI
Two-parameter-SOP and three-parameter-RSOP fiber channels: problem and solution for polarization demultiplexing using Stokes space.
Nan Cui,Xiaoguang Zhang,Zibo Zheng,Hengying Xu,Wenbo Zhang,Xianfeng Tang,Lixia Xi,Yuanyuan Fang,Liangchuan Li +8 more
TL;DR: A DSP tracking and equalization scheme for the fast time-varying RSOP using the extended Kalman filter (EKF) is proposed and is proved to be universal and can solve all the PolDemux problems based on the 2- or 3-parameter RSOP model.
Journal ArticleDOI
Window-split structured frequency domain Kalman equalization scheme for large PMD and ultra-fast RSOP in an optical coherent PDM-QPSK system.
Zibo Zheng,Nan Cui,Hengying Xu,Xiaoguang Zhang,Wenbo Zhang,Lixia Xi,Yuanyuan Fang,Liangchuan Li +7 more
TL;DR: Compared with the generally used constant modulus algorithm (CMA), the proposed Kalman scheme provides excellent performance and stability to cope with large range DGD from 20ps to 200ps and RSOP from 200krad/s to 2Mrad/s, with less computational complexity.
