[期刊论文] 作者：WenboZhang,QingyueDi,LixiaXi,XiaoguangZhang,
来源：ChineseOpticsLetters 年份：2012
To solve the problem of calibrating the polarimeter module, we design a vector projection (VP) method which is based on the theorem of vector projection and the principle of calibration. The calibration matrix can be calculated by VP method......
High order modulation format identification based on compressed sensing in optical fiber communicati
[期刊论文] 作者：BingxiangHui,XianfengTang,NaGao,WenboZhang,andXiaoguangZhang,
来源：ChineseOpticsLetters 年份：2016
We propose a method of modulation format identification based on compressed sensing using a high-order cyclic cumulant combined with a binary tree classifier. Through computing the fourth-order cyclic cumulant of the pretreated band signal,......
Improved modulation format identification based on Stokes parameters using combination of fuzzy c-me
[期刊论文] 作者：LongxueCheng,LixiaXi,DongheZhao,XianfengTang,WenboZhang,XiaoguangZhang,
来源：ChineseOpticsLetters 年份：2015
In this Letter, we develop the Stokes space-based method for modulation format identification by combing power spectral density and a cluster analysis to identify quadrature amplitude modulation (QAM) and phase-shift keying (PSK) signals. F......

A new two-stage carrier-phase recovery scheme using a combination of an optical pilot-aided algorithm with the crossed constellation transformation algorithm for either square-framed or non-square-framed M-level-quadrature amplitude modulat......
Performance analysis of LDPC code based on Watermark scheme in high-speed optical communication syst
[期刊论文] 作者：WenxueHe,WenboZhang,ChaoLi,LixiaXi,XiaoguangZhang,YaojunQiao,
来源：ChineseOpticsLetters 年份：2015
We study the decoding performance of low-density parity-check (LDPC) code based on Watermark scheme under different percentages of water-mark bits over 100 Gb/s differential quadrature phase shift keying (DQPSK) high-speed optical communica......

来源：ChineseOpticsLetters 年份：2016
We propose a modified-Viterbi and Viterbi phase estimation (VVPE) carrier phase recovery scheme that shows an effective capability of reducing the frequent and accumulated cycle slips induced by inter-symbol interference (ISI) in a faster-t......
