Journal ArticleDOI
Joint equalization scheme of ultra-fast RSOP and large PMD compensation in presence of residual chromatic dispersion
Wei Yi,Zibo Zheng,Nan Cui,Xiaoguang Zhang,Liyuan Qiu,Nannan Zhang,Lixia Xi,Wenbo Zhang,Xianfeng Tang +8 more
TL;DR: A new Kalman filter structure is proposed, which can jointly compensate ultra-fast RSOP, large PMD and RCD, and compared with CMA/MMA, the proposed Kalman scheme can provide a significant performance enhancement.
Journal ArticleDOI
Joint blind equalization of CD and RSOP using a time-frequency domain Kalman filter structure in Stokes vector direct detection system
Nan Cui,Zibo Zheng,Xiaoguang Zhang,Wei Yi,Ruipu Guo,Wenbo Zhang,Xianfeng Tang,Hengying Xu,Lixia Xi +8 more
TL;DR: The proposed time-frequency domain Kalman filter can facilitate CD compensation in the frequency domain and RSOP equalization in the time domain by exploiting a sliding window structure.
Journal ArticleDOI
An adaptive Kalman filter for extreme polarization effects equalization in coherent optical communication system
Liyuan Qiu,Zibo Zheng,Xiaoguang Zhang,Lixia Xi,Wenbo Zhang,Wei Yi,Hengying Xu,Hengying Xu,Xianfeng Tang +8 more
TL;DR: The simulation and experiment results demonstrate that the proposed adaptive Kalman filter scheme has a stable and better performance of the equalization for large PMD combined with ultrafast RSOP, with a greater tolerance the to time-varying extreme polarization environments than that using the extended Kalman filters adopted in the previous work.
Journal ArticleDOI
Joint equalization of linear impairments using two-stage cascade Kalman filter structure in coherent optical communication systems
Nannan Zhang,Wei Yi,Zibo Zheng,Nan Cui,Ruipu Guo,Liyuan Qiu,Xiaoguang Zhang,Lixia Xi,Wenbo Zhang,Hengying Xu,Hengying Xu +10 more
TL;DR: Simulations based on a 28 Gbaud polarization division multiplexed quadrature-phase shift keying coherent optical communication system show that the proposed two-stage Kalman scheme comprehensively outperforms the CMA-IMP-BPS scheme in solving the problems of RSOP, PMD, rCD, CFO, and CPN.
Proceedings ArticleDOI
Joint Blind Equalization of CD and RSOP Using Kalman Filter in Stokes Vector Direct Detection System
TL;DR: A joint blind equalization for CD and RSOP in SV-DD system based on new Kalman structure, which has strong tolerance to CD (more than 2550 ps/nm) combined with ultra-fast RSOP (up to 2Mrad/s) is proposed.
