摘要/Abstract

摘要： 超奈奎斯特传输技术作为一种非正交传输技术，近年来受到了广泛的关注.不同于传统的正交传输信号，超奈奎斯特信号的符号传输速率因为超过了奈奎斯特无码间串扰速率而带来了不可避免的符号间干扰，然而这一传输方式也被证明可以带来更高的信道容量.因此超奈奎斯特技术成为了一种具有高频谱利用率的新型传输方法，也为带宽受限的通信场景带来了新的解决方案，并且其在卫星信道以及第五代移动通信的回程链路中的应用成为了研究热点.本文对超奈奎斯特传输的概念与原理、容量计算、实现方式、检测方法以及性能与应用做了详细的总结并对其目前的技术难点进行了讨论.

Abstract: Faster-than-Nyquist (FTN) signaling,as a non-orthogonal signaling format,has been attracting a lot of attention recently. FTN signaling has a symbol rate that is higher than the Nyquist rate, which causes intersymbol interference inevitably. However, this signaling method has been proved to bring higher channel capacity. Therefore, FTN signaling has become a new bandwidth-efficient modulation method which offers a promising solution to the communication scenario with scarce bandwidth. Furthermore, faster-than-Nyquist signaling has also become a hot topic in the research of satellite communication and backhauling technique in 5G communication standard. This paper provides a summary of FTN signaling in terms of its concept and theory, capacity, implementation, detection, as well as performance and applications, respectively. Some discussions of current research difficulties are also given in the paper.

Key words: faster-than-Nyquist signaling, channel capacity, detection method
