An Overview of Communication Signal Modulation Recognition

With the increasing shortage of spectrum information resources, signal modulation processing methods are increas.ingly diversified. Modulation recognition of communication signals is widely used in civil and military fields. Therefore, theresearch on modulation identification technology has extremely important research significance and tactical value. Firstly,based on a large number of literatures, the methods based on maximum likelihood function and feature extraction are system.atically reviewed. Secondly, the deep learning recognition method is introduced from common data sets, deep neural networkstructure and existing recognition algorithms. Finally, from the perspective of unsupervised learning, open set recognitionand engineering implementation, the future development direction of modulation recognition method is prospected.
