摘要

基于FTN（超Nyquist）方案是一种高频谱效率传输方案。文章总结了目前国际上最新的基于FTN传输方案:级联多模盲均衡FTN、数字FTN和SOFTN（软输出FTN）。其中

级联多模盲均衡FTN方案能有效地抑制噪声和信道间串扰

数字FTN方案能有效地简化系统结构

而SOFTN方案的频谱效率最高。对这三种方案的性能和原理进行了详细分析和比较

以期作为未来长距离、大容量光纤通信系统设计的依据。

Abstract

The Faster-Than-Nyquist（FTN）signaling-based scheme is a high spectral efficiency transmission scheme for largecapacity optical communication systems.This paper reviews the latest FTN signaling-based transmission schemes in the world

such as cascaded multi-modulus blind equalization FTN

digital FTN and Soft Output FTN（SOFTN）.The cascaded multimodulus blind equalization FTN can effectively suppress noise and inter-channel crosstalk

the digital FTN can effectively simplify the system structure and the SOFTN has the highest spectral efficiency.It analyzes and compares in detail their performances and principles

which can be used as the basis for the design of future long-range large-capacity fiber-optic communication systems.
