Researchers have developed a new deep learning method called MAMR-IQ for recognizing modulation schemes in multi-antenna radio signal systems. This approach concatenates raw in-phase and quadrature (IQ) signals from multiple antennas and processes them through a convolutional neural network. Simulation results indicate that MAMR-IQ surpasses existing methods in both accuracy and computational efficiency, and a proposed data augmentation technique further enhances its performance, particularly in scenarios with limited training data.
