Abstract

Nyquist sinc-pulse shaping provides spectral efficiencies close to the theoretical limit. In this paper we discuss the analogy to optical orthogonal frequency division multiplexing and compare both techniques with respect to spectral efficiency and peak to average power ratio. We then show that using appropriate algorithms, Nyquist pulse shaped modulation formats can be encoded on a single wavelength at speeds beyond 100 Gbit/s in real-time. Finally we discuss the proper reception of Nyquist pulses.

摘要

奈奎斯特 sinc 脉冲整形可提供接近理论极限的频谱效率。在本文中，我们讨论了与光正交频分复用的类比，并在频谱效率和峰均功率比方面对这两种技术进行了比较。然后我们表明，使用适当的算法，奈奎斯特脉冲整形调制格式可以在单个波长上以超过 100 Gbit/s 的速度实时编码。最后，我们讨论了奈奎斯特脉冲的正确接收。
