Abstract

This article presents a survey of current spectrum sensing (SS) research involving the application of image processing and deep learning techniques. This document includes approaches to narrowband, wideband, and cooperative SS. A current trend, automatic classification modulation (AMC), is also included in this review. It is closely related to SS by recognizing the spectrum availability and classifying the signal type currently using the licensed band of interest. This chapter is helpful for comparison of the current tendencies in spectrum sensing in terms of signal simulation, including different analog and digital modulation types, image-based approaches such as covariance matrix or spectrogram, and wireless channel simulations. The extensive review included in this document mainly focuses on deep learning architectures and image processing techniques that can help improve CR systems' detection probability to maximize the underutilized RF spectrum in 5G.
