Reconfigurable Intelligent Surface-assisted Classification of Modulations using Deep Learning

Research output: Chapter in Book/Report/Conference proceedingConference Contribution (Conference Proceeding)


The fifth generating (5G) of wireless networks will be more adaptive and heterogeneous. Reconfigurable intelligent surface technology enables the 5G to work on multistrand waveforms. However, in such a dynamic network, the identification of specific modulation types is of paramount importance. We present a RIS-assisted digital classification method based on artificial intelligence. We train a convolutional neural network to classify digital modulations. The proposed method operates and learns features directly on the received signal without feature extraction. The features learned by the convolutional neural network are presented and analyzed. Furthermore, the robust features of the received signals at a specific SNR range are studied. The ac-curacy of the proposed classification method is found to be remarkable, particularly for low levels of SNR.
