Feature Analysis of Time and Frequency Domain for Automatic Modulation Classification

Abstract

In this study, determination of the type of digital modulation of received signal in communication systems was aimed. For this purpose, high order cumulants, which are the most addressed ones, and frequency-based features were together examined for improving performance of classifier. Simulation studies were performed to evaluate the effect of these features on performance of classifier, both separately and together. Performed simulation studies showed that the proposed approach had higher performance
