Researchers have developed a new framework for semantic communication in connected autonomous vehicles (CAVs) that utilizes a Variational Autoencoder (VAE) for satellite-assisted driving. This VAE-driven approach focuses on transmitting task-relevant semantic features rather than raw data, which is particularly beneficial for bandwidth-constrained satellite channels. The framework is designed to optimize both traffic sign reconstruction and classification tasks simultaneously, demonstrating significant bandwidth reductions of up to 98.17% while maintaining stable performance under various signal-to-noise conditions.
