| 摘 要： | 提出了一种新型的基于串行结构的最小频移键控调制技术,产生了相位连续,频谱宽度窄,每码元时间有两次π/2相移,类似于传统最小频移键控调制信号,给出了该调制方案的理论推导,并将其应用于8进制的多维多阶调制系统中。理论和仿真分析了不同的8进制调制方案在频谱特性,残留色散容限,自相位调制容限的不同,还分析了其受到系统滤波带宽的影响。最后仿真实现了通过350km的色散完全补偿的光纤120Gb/s的数据传输。

| Abstract: | An advanced serial minimum frequency-shift keying (SMSK) modulation scheme is proposed. SMSK signal has a narrow power spectrum, and continuous phase shift that changes π/2 twice during one symbol time, which is similar to traditional minimum frequency-shifts (MSK) signal. The principle of generating the optical SMSK signal and its implementation in octal multi-dimensional and multi-level modulation scheme is presented. Theoretical analysis is given to modulated spectra, residual dispersion tolerance, self-phase modulation (SPM) tolerance and effect of filter bandwidth on it. 120 Gb/s simulated transmission over 350 km fiber link with dispersion compensation is demonstrated. |
