摘要

先进的调制技术可以有效地改善光通信系统抵御色散、偏振模和非线性等损伤的能力

是超高速光通信系统中的重要技术。MSK（最小频移键控）是一种恒包络调制技术

具有色散容限较大和能量集中等优点

文章将MSK调制引入PM（偏振复用）系统

提出了一种适应于超高速光通信系统的PM-MSK调制方案。理论分析和数值仿真结果表明

该方案与RZ（归零）和QPSK（正交频移键控）方案相比

具有更好的误码率性能。

Abstract

As an important technology for ultra-high-rate optical communication systems

advanced modulation technology can effectively improve their capabilities to withstand such adverse effects as chromatic dispersion

polarization mode dispersion and nonlinear effect.Minimum Shift Keying（MSK）is a constant envelope modulation technology with many advantages such as large dispersion tolerance and power concentration.This paper proposes an improved modulation scheme for ultra-high-rate optical communication systems

namely PM-MSK modulation scheme

in which MSK modulation is introduced into the Polarization Multiplexing（PM）system.Theoretical analysis and numerical simulation results show that this scheme has better BER performance than RZ and QPSK schemes.
