Anefficient and 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) approach 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 was collected in a complicated environment, including carrier frequency offset (CFO), phase noise (PN), and distinct signal-to-noise ratios (SNR). Through experimental simulation, an improvement in the classification accuracies was achieved. In particular, the outstanding accuracy rates achieved are 98.68% and 96.05% using ResNet18 and ResNet101, respectively. Furthermore, these models can classify the modulated signals at lower SNRs. These innovative models are suitable and effective to utilize for 6G wireless communication networks.
