CNN-LSTM Hybrid Architecture for Over-the-Air Automatic Modulation Classification Using SDR

arXiv — cs.CVThursday, November 27, 2025 at 5:00:00 AM
  • A new study presents a hybrid architecture combining Convolutional Neural Networks (CNN) and Long Short-Term Memory (LSTM) networks for Automatic Modulation Classification (AMC) using Software Defined Radio (SDR). This system effectively identifies modulation schemes in real-time without prior knowledge, demonstrating its capability by recognizing over-the-air signals from a custom FM transmitter.
  • The development of this AMC system is significant as it enhances the efficiency and accuracy of wireless communication systems, which are crucial for applications like cognitive radio and spectrum monitoring. The integration of CNNs for spatial feature extraction and LSTMs for temporal dependencies marks a notable advancement in signal processing technology.
  • This innovation reflects a broader trend in artificial intelligence where hybrid models are increasingly utilized across various domains, from agriculture to healthcare. The successful application of deep learning frameworks in diverse fields underscores the growing importance of AI in enhancing operational efficiencies and decision-making processes.
