Abstract

For several reasons, modulation recognition is extremely important in wireless communication. In this paper, a common method, based on fourth-order and sixth-order cumulants, is proposed to recognize the modulation of digital signals in the device. Automatic modulation recognition is a fundamental step to perform the classification of different modulation formats. It is very important both in military and civil applications. Different signal transmission requires different modulation. These modulation makes user convenient to work in such communication field. This device is mainly used to recognize the modulation of the digital signals automatically. The function of the device is mainly used to distinguish different digital signals.
