奈奎斯特自脉冲整形提供了接近理论极限的频谱效率。在本文中，我们讨论了光正交频分复用的类比，并比较了两种技术的频谱效率和峰值平均功率比。然后，我们展示了使用适当的算法，奈奎斯特脉冲形状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。最后讨论奈奎斯特脉冲的正确接收。(C) 2011美国光学学会
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. (C) 2011 Optical Society of America
