摘要：
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. © 2020, Chinese Institute of Electronics. All right reserved.
