A Survey on Deep Learning Techniques in Wireless Signal Recognition

Abstract EN

Wireless signal recognition plays an important role in cognitive radio, which promises a broad prospect in spectrum monitoring and management with the coming applications for the 5G and Internet of Things networks.

Therefore, a great deal of research and exploration on signal recognition has been done and a series of effective schemes has been developed.

In this paper, a brief overview of signal recognition approaches is presented.

More specifically, classical methods, emerging machine learning, and deep leaning schemes are extended from modulation recognition to wireless technology recognition with the continuous evolution of wireless communication system.

In addition, the opening problems and new challenges in practice are discussed.

Finally, a conclusion of existing methods and future trends on signal recognition is given.
