信号调制样式的自动识别是非协作通信中的主要问题,也是近年来信号处理领域研究的热点问题,近几十年来,人们在这方面作了大量有益的探索,提出了很多新思路和新方法。本文对目前调制识别的研究内容、现有方法作了一个综述,并对以后的发展提出一些看法。
Automatic recognition of signal modulation pattern is the main problem in non-cooperative communication. It is also a hot issue in the field of signal processing in recent years. In recent decades, people have made a lot of useful explorations in this field and proposed many new ideas and methods. In this paper, the current research on modulation recognition, the existing methods are reviewed, and some suggestions for the future development.
