Deep Learning-Based Demodulation of Radio Signal

2022

M-ary quadrature amplitude modulation (M-QAM) modulated signal is commonly used in digital telecommunication systems for its arbitrarily high spectral efficiencies limited only by the noise level and linearity of the communications channel. Typical demodulation techniques …

Learning Energy-Based Generative Models via Potential Flow: A Variational Principle Approach to Probability Density Homotopy Matching

2025 · arXiv (Cornell University)

Energy-based models (EBMs) are a powerful class of probabilistic generative models due to their flexibility and interpretability. However, relationships between potential flows and explicit EBMs remain underexplored, while contrastive divergence training via implicit Markov chain …
