摘要:
文章讨论了现代光通信系统中关键技术,特别是数字信号处理(DSP)技术在其中的应用,主要针对光纤通信系统中不同的干扰与损伤效应以及先进的DSP信号调制与补偿方法进行分析讨论;介绍了一种用于光纤通信系统的新型DSP调制技术——正交啁啾复用(OCDM)技术。由于OCDM具有优良的抗干扰能力并可以有效地利用简单的单抽头频域均衡器,相比于其他系统,基于OCDM的光纤通信系统表现出优良的传输性能并保持类似的系统复杂度。文章展示了该OCDM技术分别应用在基于相干光系统的长距传输与基于光强调制直接检测系统的短距传输的研究进展,以及在相应条件下与正交频分复用技术(OFDM)的实验对比。
Abstract:
It discussed the key enabling technologies in modern fiber-optic systems, especially the applications of digital signal processing (DSP) technologies for compensating the detrimental effects in the optical fiber. In particular, we showed how the advanced DSP techniques realize signal modulation and channel compensation to deal with the interference and impairments in the fiber-optic systems. Moreover, this paper introduced a recently proposed orthogonal chirp-division multiplexing (OCDM) as an advanced modulation technique for fiber-optic systems. In virtue of its robustness against the system impairments and capability of utilizing single-tap frequency-domain equalization, the OCDM systems exhibit superior performance than orthogonal frequency-division multiplexing (OFDM) with similar system complexity. We discussed recent progress on OCDM in both the coherent lightwave system for long-haul transmission and the intensity-modulation and directed-detection systems for short-reach transmission. Most recent experimental results were also provided in comparison with the orthogonal frequency-division multiplexing (OFDM).
