摘要
阐述了双偏振正交相移键控(DP-QPSK)系统的调制编码和检测原理,详细描述关于DP-QPSK40Gb/s WDM系统结构和性能的最新研究进展,并将DP-QPSK与Duo-Binary、DPSK和DQPSK等几种调制编码方式进行了全面比较,展示了DP-QPSK作为一种新兴的调制方式,在40Gb/s系统研究领域具有很高的研究价值和广泛的应用前景。
The principle of modulation and detection of Dual-Polarization Quadrature Phase Shift Keying (DP-QPSK) is described in this paper. And then, up to date research of the structure and advantages of the DP-QPSK 40Gb/s WDM system is demonstrated in detail. We also draw a full comparison among the DP-QP-SK and other modulations employed in 40Gb/s WDM systems such as Duo-Bianry, QPSK, DQPSK. In conclusion, the DP-QPSK modulation has vast of applied foreground and research value in the research area of the 40Gb/s systems as a newly arisen modulation.
