Abdallah Techniques Engineering Department, Technical Engineering College, Northern Technical University, Ninevah, Iraq Journal Article 2024 08 03 An efficient and a remarkable automatic modulation classification (AMC) technique is essential with the advent of sixth-generation (6G) communication systems. Using the pre-trained convolutional neural network (CNN), a deep learning (DL) approaches to classify eight types of digital modulated signals. National Instrument LabVIEW NXG is used to build the modulation transceivers at 100 GHz a 6G carrier frequency. The dataset collected at a complicated environments including carrier frequency offset (CFO), phase noise (PN), and at distinct signal-to-noise ratios (SNR).Through experimental simulation, an improvement in the classification accuracies were achieved. In particular, the outstanding accuracy rates achieved are 98.68% and 96.05% using ResNet18 and ResNet101, respectively. Furthermore, these models have the ability to classify the modulated signals at lower SNRs. These innovative models are suitable and effective to utilize for 6G wireless communication networks.
